And Eadweard Muybridge's primitive motion studies (from 1884-1887) included test footage with cinematic glimpses of naked men and women. Lois Weber's and Paramount's 4-reel silent film Hypocrites (1914) featured full female nudity in the guise of an unclad lady (Margaret Edwards) - 'the Naked Truth' - who occasionally appeared as a transitional plot element between scenes.


I asked Herbenick whether the NSSHB’s findings gave her any hunches about what might have changed since the 1990s. She mentioned the new popularity of sex toys, and a surge in heterosexual anal sex. Back in 1992, the big University of Chicago survey reported that 20 percent of women in their late 20s had tried anal sex; in 2012, the NSSHB found a rate twice that. She also told me about new data suggesting that, compared with previous generations, young people today are more likely to engage in sexual behaviors prevalent in porn, like the ones she warns her students against springing on a partner. All of this might be scaring some people off, she thought, and contributing to the sex decline.
Insect species make up more than two-thirds of all extant animal species. Most insect species reproduce sexually, though some species are facultatively parthenogenetic. Many insects species have sexual dimorphism, while in others the sexes look nearly identical. Typically they have two sexes with males producing spermatozoa and females ova. The ova develop into eggs that have a covering called the chorion, which forms before internal fertilization. Insects have very diverse mating and reproductive strategies most often resulting in the male depositing spermatophore within the female, which she stores until she is ready for egg fertilization. After fertilization, and the formation of a zygote, and varying degrees of development, in many species the eggs are deposited outside the female; while in others, they develop further within the female and are born live.
Iris observed that her female friends, who were mostly single, were finding more and more value in their friendships. “I’m 33, I’ve been dating forever, and, you know, women are better,” she said. “They’re just better.” She hastened to add that men weren’t bad; in fact, she hated how anti-male the conversations around her had grown. Still, she and various platonic female friends—most of whom identified as straight—were starting to play roles in one another’s lives that they might not be playing if they had fulfilling romantic or sexual relationships. For instance, they’d started trading lesbian-porn recommendations, and were getting to know one another’s preferences pretty well. Several women also had a text chain going in which they exchanged nude photos of themselves. “It’s nothing but positivity,” she said, describing the complimentary texts they’d send one another in reply to a photo (“Damn, girl, your tits!”). She wasn’t ready to swear off men entirely. But, she said, “I want good sex.” Or at least, she added, “pretty good sex.”
So why do people continue to use dating apps? Why not boycott them all? Simon said meeting someone offline seemed like less and less of an option. His parents had met in a chorus a few years after college, but he couldn’t see himself pulling off something similar. “I play volleyball,” he added. “I had somebody on the volleyball team two years ago who I thought was cute, and we’d been playing together for a while.” Simon wanted to ask her out, but ultimately concluded that this would be “incredibly awkward,” even “boorish.”
Quite often couple experiment with different positions but do not get the desired result. Why? Because you need to understand every one, to understand what it gives to the man and to the woman. Apart from visual perception you need to understand clearly what and how to stimulate in this or that pose, with what areas of vagina your penis interacts and what its part.
This shift is particularly striking when you consider that Western civilization has had a major hang-up about masturbation going back at least as far as Onan. As Robert T. Michael and his co-authors recount in Sex in America, J. H. Kellogg, the cereal maker, urged American parents of the late 19th century to take extreme measures to keep their children from indulging, including circumcision without anesthetic and application of carbolic acid to the clitoris. Thanks in part to his message, masturbation remained taboo well into the 20th century. By the 1990s, when Michael’s book came out, references to masturbation were still greeted with “nervous titters or with shock and disgust,” despite the fact that the behavior was commonplace.

Anna, who graduated from college three years ago, told me that in school, she struggled to “read” people. Dating apps have been a helpful crutch. “There’s just no ambiguity,” she explained. “This person is interested in me to some extent.” The problem is that the more Anna uses apps, the less she can imagine getting along without them. “I never really learned how to meet people in real life,” she said. She then proceeded to tell me about a guy she knew slightly from college, whom she’d recently bumped into a few times. She found him attractive and wanted to register her interest, but wasn’t sure how to do that outside the context of a college party. Then she remembered that she’d seen his profile on Tinder. “Maybe next time I sign in,” she said, musing aloud, “I’ll just swipe right so I don’t have to do this awkward thing and get rejected.”

The main hero of this game is Michael. He just graduated school and now he has to decide what to do next in his life. However he end up as a guest on Allison's yacht. She's incredibly rich. She has some problems because FBI is investigating something about her company. Turns out you're involved to FBI, but you like her daughters and now you are mixing your duty and sexual desires.
The internet has made it so easy to gratify basic social and sexual needs that there’s far less incentive to go out into the “meatworld” and chase those things. This isn’t to say that the internet can give you more satisfaction than sex or relationships, because it doesn’t … [But it can] supply you with just enough satisfaction to placate those imperatives … I think it’s healthy to ask yourself: “If I didn’t have any of this, would I be going out more? Would I be having sex more?” For a lot of people my age, I think the answer is probably yes.
It’s important to recognise that we’re all different, and that the things that feel right for us are different from the things that feel right for someone else. We should be respectful of and positive about other people’s sexuality or sexual relationships, and support their right to explore their sexuality in a safe, consensual and responsible way.
Sexual disorders, according to the DSM-IV-TR, are disturbances in sexual desire and psycho-physiological changes that characterize the sexual response cycle and cause marked distress and interpersonal difficulty. The sexual dysfunctions is a result of physical or psychological disorders. The physical causes include hormonal imbalance, diabetes, heart disease and more. The psychological causes includes but are not limited to stress, anxiety, and depression.[51] The sexual dysfunction affects men and women. There are four major categories of sexual problems for women: desire disorders, arousal disorders, orgasmic disorders, and sexual pain disorders.[8][page needed] The sexual desire disorder occurs when an individual lacks the sexual desire because of hormonal changes, depression, and pregnancy.The arousal disorder is a female sexual dysfunction. Arousal disorder means lack of vaginal lubrication. In addition, blood flow problems may affect arousal disorder. Lack of orgasm, also known as, anorgasmia is another sexual dysfunction in women. The anorgasmia occurs in women with psychological disorders such as guilt and anxiety that was caused by sexual assault. The last sexual disorder is the painful intercourse. The sexual disorder can be result of pelvic mass, scar tissue, sexually transmitted disease and more.[52] There are also three common sexual disorders for men including, sexual desire, ejaculation disorder, and erectile dysfunction. The lack of sexual desire in men is because of loss of libido, low testosterone. There are also psychological factors such as anxiety, and depression.[53] The ejaculation disorder has three types: retrograde ejaculation, retarded ejaculation, premature ejaculation. The erectile dysfunction is a disability to have and maintain an erection during intercourse.[54]
And Eadweard Muybridge's primitive motion studies (from 1884-1887) included test footage with cinematic glimpses of naked men and women. Lois Weber's and Paramount's 4-reel silent film Hypocrites (1914) featured full female nudity in the guise of an unclad lady (Margaret Edwards) - 'the Naked Truth' - who occasionally appeared as a transitional plot element between scenes.
Either of two divisions, male and female, into which most sexually reproducing organisms are grouped. Sex is usually determined by anatomy, the makeup of the sex chromosomes, and the type and amount of hormones produced. When the sex of an organism is determined by the sex chromosomes, males and females are generally produced in equal numbers. In other organisms, such as bees and wasps, in which females develop from fertilized eggs and males develop from unfertilized eggs, distribution of the sexes is unequal.
The most basic sexual system is one in which all organisms are hermaphrodites, producing both male and female gametes—[citation needed] this is true of some animals (e.g. snails) and the majority of flowering plants.[34] In many cases, however, specialization of sex has evolved such that some organisms produce only male or only female gametes. The biological cause for an organism developing into one sex or the other is called sex determination.
As a dude’s sexual preferences may not always be what’ll get a  lady to the finish line, some sex experts and adult performers have chimed in with the best positions that are most likely to please women. It seems that while yoga-tastic, wildly inventive advanced sex positions may be great for a change now and then, what women really want the most is simple: missionary.
Sexual reproduction is a process specific to eukaryotes, organisms whose cells contain a nucleus and mitochondria. In addition to animals, plants, and fungi, other eukaryotes (e.g. the malaria parasite) also engage in sexual reproduction. Some bacteria use conjugation to transfer genetic material between cells; while not the same as sexual reproduction, this also results in the mixture of genetic traits.

In exchanges like these, I was struck by what a paralyzing and vicious cycle unhappiness and abstinence can be. The data show that having sex makes people happier (up to a point, at least; for those in relationships, more than once a week doesn’t seem to bring an additional happiness bump). Yet unhappiness inhibits desire, in the process denying people who are starved of joy one of its potential sources. Are rising rates of unhappiness contributing to the sex recession? Almost certainly. But mightn’t a decline in sex and intimacy also be leading to unhappiness?
Humans, bonobos and dolphins show cooperative behaviour. In many cases, this behaviour has shown better results than what an individual can achieve alone. In these animals, the use of sex has evolved beyond reproduction and has taken additional social functions. Sex reinforces intimate social bonds between individuals. Overall, such cooperation also benefits each member of the group in that they are better able to survive.

Another midshipman, according to an annual Defense Department report on misconduct at the service academies, was charged and convicted of sexual assault in late 2017 after assaulting a female classmate. The male midshipman was dismissed from the Navy after a court-martial and sentenced to 30 months confinement. He also registered as a sex offender.
We’ve already mentioned that the best sex poses are those which suit best you and your partner. You will not learn about these ones in fashionable magazines and web-papers – you will need to find out them by yourself. Right about it we are going to talk now, and exactly about how to experiment with positions for sex with the purpose to determine the best ones for you and your partner. Let’s study 7 important rules, which will help you with that. Read more…
Anal sex is when an erect penis or other device made for sexual pleasure is inserted into the sexual partner's anus. Anal sex with a female does not lead to pregnancy by itself, however, semen can leak out of the anus and enter into the vagina, and pregnancy may rarely occur. Anal sex can still pass sexually transmitted diseases from one partner to another. It can also be very unhealthy for the body because the skin around the anus can tear, bleed and get infected with bacteria.[15] For safety and pleasure partners often use condoms, female condoms and/or lubrication.
To be honest, though, all of the talk about sexual health doesn’t seem to have influenced the day-to-day particulars of our work. Sex still is primarily seen as a set of risk factors that we counsel against. I am convinced that this perspective on sex and sexuality as “risk” legitimates the stigma associated with sexually transmitted infections and contributes to our society’s poisonous intolerance of sexual diversity. A sexual health perspective incorporates the concept of personal and epidemiologic risks of sex, but recognizes the pervasive importance of sex in our lives.
"On the Basis of Sex" is a bio-pic about the early years in Ruth Bader Ginsburg's career. As the movie opens, she is a first year student at Harvard Law. When her husband Martin, himself a second year student there, becomes gravely ill, she attends both her own and Martin's classes, and of course caring for him. A couple of years later, Martin is hired by a prominent New York law firm, and Ruth transfers to Columbia Law to finish her law degree. She graduates top of the class, yet not a single law firm in New York offers her a job... At this point we are less than 15 min. into the movie but to tell you more of the plot would spoil your viewing experience, you'll just have to see for yourself how it all plays out.
I loved Simon and Abby's story. They were each remarkable people. People I'd want for friends or coworkers. I'll admit it, I want Simon for MY boyfriend, darling little girl and all. Watching Simon play with Hayden (the five-year-old) was beyond sweet. He's the daddy every child needs, and it's no wonder Abby was already in love with him, whether she'd admit it or not. Yes, lust or at least serious attraction first, because Simon was beyond gorgeous. The entire package. The body and the heart. We knew exactly how Simon would treat Abby, and watching their love story develop and blossom was a real treat.
Speaking in Miami on July 27, 2016, Trump gave the final and weirdest press conference of his campaign. Calling the spectacle “bizarre even by Trump’s standards”—how naive I was!—I wrote, “Just when it starts to seem that Donald Trump can’t surprise the jaded American media anymore, the Republican nominee manages to go just a little bit further.” There was much to chew over (and spit out) in Trump’s comments that day, but the most enduring moment came when the Republican nominee answered a question about Kremlin interference in the election. Trump looked to the cameras and gave one of the more stunning remarks of his campaign.
The very first kiss on film was between a Victorian couple seen in the Edison kinetoscope The May Irwin Kiss (1896) (aka The Kiss, or The Irwin-Rice Kiss in a filmed scene from the stage play The Widow Jones). This titillating short 20-second film, with a close-up of a kiss, was denounced as shocking and pornographic to early moviegoers and caused the Roman Catholic Church to call for censorship.

In the United States, there are two fundamentally different approaches, applied in different states, regarding the way the law is used to attempt to govern a person's sexuality. The “black letter” approach to law focuses on the study of pre-existing legal precedent, and attempts to offer a clear framework of rules within which lawyers and others can work.[127] In contrast, the socio-legal approach focuses more broadly on the relationship between the law and society, and offers a more contextualized view of the relationship between legal and social change.[127] Both approaches are used to guide changes in the legal system of states, and both have an effect.[citation needed]
Psychological theories exist regarding the development and expression of gender differences in human sexuality. A number of them, including neo-analytic theories, sociobiological theories, social learning theory, social role theory, and script theory, agree in predicting that men should be more approving of casual sex (sex happening outside a stable, committed relationship such as marriage) and should also be more promiscuous (have a higher number of sexual partners) than women. These theories are mostly consistent with observed differences in males' and females' attitudes toward casual sex before marriage in the United States; other aspects of human sexuality, such as sexual satisfaction, incidence of oral sex, and attitudes toward homosexuality and masturbation, show little to no observed difference between males and females. Observed gender differences regarding the number of sexual partners are modest, with males tending to have slightly more than females.[14]
Sperm are transported through a four-part duct system. The first part of this system is the epididymis. The testicles converge to form the seminiferous tubules, coiled tubes at the top and back of each testicle. The second part of the duct system is the vas deferens, a muscular tube that begins at the lower end of the epididymis.[8][page needed] The vas deferens passes upward along the side of the testicles to become part of the spermatic cord.[23] The expanded end is the ampulla, which stores sperm before ejaculation. The third part of the duct system is the ejaculatory ducts, which are 1-inch (2.5 cm)-long paired tubes that pass through the prostate gland, where semen is produced.[8][page needed] The prostate gland is a solid, chestnut-shaped organ that surrounds the first part of the urethra, which carries urine and semen.[8][page needed][23] Similar to the female G-spot, the prostate provides sexual stimulation and can lead to orgasm through anal sex.[27]

These messages are echoed and amplified by a Salt Lake City–based nonprofit called Fight the New Drug—the “drug” being porn—which has delivered hundreds of presentations to schools and other organizations around the country, including, this spring, the Kansas City Royals. The website NoFap, an offshoot of a popular Reddit message board founded by a now-retired Google contractor, provides community members (“fapstronauts”) a program to quit “fapping”—masturbating. Further outside the mainstream, the far-right Proud Boys group has a “no wanks” policy, which prohibits masturbating more than once a month. The group’s founder, Gavin McInnes, who also co-founded Vice Media, has said that pornography and masturbation are making Millennials “not even want to pursue relationships.”
So why do people continue to use dating apps? Why not boycott them all? Simon said meeting someone offline seemed like less and less of an option.

Like animals, plants have developed specialized male and female gametes.[31] Within seed plants, male gametes are contained within hard coats, forming pollen. The female gametes of seed plants are contained within ovules; once fertilized by pollen these form seeds which, like eggs, contain the nutrients necessary for the development of the embryonic plant.

Do you think that practicing safe sex takes the joy out of sex? It doesn't have to. Safe sex practices simply combine the greatest pleasure with the least risk of contracting HIV and other sexually transmitted infections (STIs), such as herpes or syphilis. Safe sex can actually enhance your sex life by increasing communication and trust between you and your sexual partners.

In many organisms, the haploid stage has been reduced to just gametes specialized to recombine and form a new diploid organism; in others, such as cryptogamic plants the gametes are capable of undergoing cell division to produce multicellular haploid organisms. In either case, gametes may be externally similar, particularly in size (isogamy), or may have evolved an asymmetry such that the gametes are different in size and other aspects (anisogamy).[23] By convention, the larger gamete (called an ovum, or egg cell) is considered female, while the smaller gamete (called a spermatozoon, or sperm cell) is considered male. An individual that produces exclusively large gametes is female, and one that produces exclusively small gametes is male.[24] An individual that produces both types of gametes is a hermaphrodite; in some cases hermaphrodites are able to self-fertilize and produce offspring on their own, without a second organism.[25]

Shortly after the Lumieres conducted the first public screening of a film (in December 1895), pioneering French film-maker Georges Melies directed the very short B/W 'adult' film Après Le Bal (1897, Fr.) (After the Ball, Bath) with one of the earliest nude scenes in film history. Reportedly around the same time, "blue movie" pornographer Eugene Pirou pioneered the risque film (called "smoking concert" or stag party films) when he produced the slightly erotic Le Coucher de la Marie (1896, Fr.) (aka Bedtime for the Bride) in which Louise Willy performed the first strip tease onscreen during a bathing scene -- the short pornographic film (of which only a few minutes exist) was directed by Léar (real name Albert Kirchner).


Learning sex in the context of one-off hookups isn’t helping either. Research suggests that, for most people, casual sex tends to be less physically pleasurable than sex with a regular partner. Paula England, a sociologist at NYU who has studied hookup culture extensively, attributes this partly to the importance of “partner-specific sexual skills”—that is, knowing what your partner likes. For women, especially, this varies greatly. One study found that while hooking up with a new partner, only 31 percent of men and 11 percent of women reached orgasm. (By contrast, when people were asked about their most recent sexual encounter in the context of a relationship, 84 percent of men and 67 percent of women said they’d had an orgasm.) Other studies have returned similar results. Of course, many people enjoy encounters that don’t involve orgasms—a third of hookups don’t include acts that could reasonably be expected to lead to one—but the difference between the two contexts is striking. If young people are delaying serious relationships until later in adulthood, more and more of them may be left without any knowledge of what good sex really feels like.
Slangs for oral sex is common in Western cultures, for example: "going down on", "giving a blowjob", "giving head", or "eating out". The technical term for oral sex is fellatio if performed on a male and cunnilingus if performed on a female. When a man performs fellatio on himself, it is called autofellatio, and autocunnilingus if a woman performs cunnilingus on herself. Few men and women are able to do this.

Among humans and other mammals, males typically carry an X and a Y chromosome (XY), whereas females typically carry two X chromosomes (XX), which are a part of the XY sex-determination system. Humans may also be intersex. Other animals have different sex-determination systems, such as the ZW system in birds, the X0 system in insects, and various environmental systems, for example in crustaceans. Fungi may also have more complex allelic mating systems, with sexes not accurately described as male, female, or hermaphroditic.[3]
Some STIs can also be spread in ways other than having sex. For example, herpes simplex and hepatitis B could be caught by a virgin without having sex, but can also be caught through sex. Some types of STIs can spread from contact between the genitals, mouth, anus, skin, eyes, and (rarely) infected surfaces; this depends a lot on the type of STI and how it spreads. Some common diseases like HPV can cause warts and cancer in the genitals or anus or throat.
1650s, "of or pertaining to the fact of being male or female," from Late Latin sexualis "relating to sex," from Latin sexus (see sex (n.)). Meaning "pertaining to copulation or generation" is from 1766; sexual intercourse attested by 1778; sexual orientation by 1967; sexual harassment by 1975. Sexual revolution attested by 1962. Sexual politics is from 1970. Related: Sexually.

The evolution of sexual reproduction is a major puzzle because asexual reproduction should be able to outcompete it as every young organism created can bear its own young. This implies that an asexual population has an intrinsic capacity to grow more rapidly with each generation.[4] This 50% cost is a fitness disadvantage of sexual reproduction.[5] The two-fold cost of sex includes this cost and the fact that any organism can only pass on 50% of its own genes to its offspring. One definite advantage of sexual reproduction is that it impedes the accumulation of genetic mutations.[6]
Interest in sexual activity typically increases when an individual reaches puberty.[6] Opinions differ on the origins of an individual's sexual orientation and sexual behavior. Some argue that sexuality is determined by genetics, while others believe it is molded by the environment, or that both of these factors interact to form the individual's sexual orientation.[5] This pertains to the nature versus nurture debate. In the former, one assumes that the features of a person innately correspond to their natural inheritance, exemplified by drives and instincts; the latter refers to the assumption that the features of a person continue to change throughout their development and nurturing, exemplified by ego ideals and formative identifications.
Sexual dimorphisms in animals are often associated with sexual selection—the competition between individuals of one sex to mate with the opposite sex.[42] Antlers in male deer, for example, are used in combat between males to win reproductive access to female deer. In many cases the male of a species is larger than the female. Mammal species with extreme sexual size dimorphism tend to have highly polygynous mating systems—presumably due to selection for success in competition with other males—such as the elephant seals. Other examples demonstrate that it is the preference of females that drive sexual dimorphism, such as in the case of the stalk-eyed fly.[43]
Everybody says and writes that changing positions in sex is good, that knowing their different options will make your sexual life diversified and so on. But why, how and what advantages does it give? There are a few nuances and secrets that not many people know. Unfortunately, not many people talk and write about it that is why now we will have a good at it and as they say, we will make it loud and simple. Read more…
Fertilization creates a single-celled zygote which includes genetic material from both gametes. In a process called genetic recombination, genetic material (DNA) joins up so that homologous chromosome sequences are aligned with each other, and this is followed by exchange of genetic information. Two rounds of cell division then produce four daughter cells with half the number of chromosomes from each original parent cell, and the same number of chromosomes as both parents. For instance, in human reproduction each human cell contains 46 chromosomes in 23 pairs. Meiosis in the parents' gonads produce gamete cells which only contain 23 chromosomes each. When the gametes are combined via sexual intercourse to form a fertilized egg, the resulting child will have 23 chromosomes from each parent genetically recombined into 23 chromosome pairs or 46 total.
Two animals coming together for the purposes of sexual reproduction is called mating. Most animals only mate when the female is at the point of estrus, which is the most fertile period of time in its reproductive cycle.[5][6] In certain animals, sexual intercourse is not only used for reproduction, but has taken other functions as well. These animals include bonobos,[7] dolphins,[8] and chimpanzees which also have sexual intercourse even when the female is not in estrus, and to engage in sex acts with same-sex partners.[9] In most instances, humans have sex primarily for pleasure.[10] This behavior in the above mentioned animals is also presumed to be for pleasure,[11] which in turn strengthens social bonds.
I mentioned to several of the people I interviewed for this piece that I’d met my husband in an elevator, in 2001. (We worked on different floors of the same institution, and over the months that followed struck up many more conversations—in the elevator, in the break room, on the walk to the subway.) I was fascinated by the extent to which this prompted other women to sigh and say that they’d just love to meet someone that way. And yet quite a few of them suggested that if a random guy started talking to them in an elevator, they would be weirded out. “Creeper! Get away from me,” one woman imagined thinking. “Anytime we’re in silence, we look at our phones,” explained her friend, nodding. Another woman fantasized to me about what it would be like to have a man hit on her in a bookstore. (She’d be holding a copy of her favorite book. “What’s that book?” he’d say.) But then she seemed to snap out of her reverie, and changed the subject to Sex and the City reruns and how hopelessly dated they seem. “Miranda meets Steve at a bar,” she said, in a tone suggesting that the scenario might as well be out of a Jane Austen novel, for all the relevance it had to her life.

Human sexuality is the way people experience and express themselves sexually.[1][2] This involves biological, erotic, physical, emotional, social, or spiritual feelings and behaviors.[3][4] Because it is a broad term, which has varied over time, it lacks a precise definition.[4] The biological and physical aspects of sexuality largely concern the human reproductive functions, including the human sexual response cycle.[3][4] Someone's sexual orientation can influence that person's sexual interest and attraction for another person.[5] Physical and emotional aspects of sexuality include bonds between individuals that are expressed through profound feelings or physical manifestations of love, trust, and care. Social aspects deal with the effects of human society on one's sexuality, while spirituality concerns an individual's spiritual connection with others. Sexuality also affects and is affected by cultural, political, legal, philosophical, moral, ethical, and religious aspects of life.[3][4]
Though attempts have been made to devise objective criteria of sexual attractiveness, and measure it as one of several bodily forms of capital asset (see erotic capital), a person's sexual attractiveness is to a large extent a subjective measure dependent on another person's interest, perception, and sexual orientation. For example, a gay or lesbian person would typically find a person of the same sex to be more attractive than one of the other sex. A bisexual person would find either sex to be attractive. In addition, there are asexual people, who usually do not experience sexual attraction for either sex, though they may have romantic attraction (homoromantic, biromantic or heteroromantic). Interpersonal attraction includes factors such as physical or psychological similarity, familiarity or possessing a preponderance of common or familiar features, similarity, complementarity, reciprocal liking, and reinforcement.[126]
While the evolution of sex dates to the prokaryote or early eukaryote stage,[13] the origin of chromosomal sex determination may have been fairly early in eukaryotes (see evolution of anisogamy). The ZW sex-determination system is shared by birds, some fish and some crustaceans. XY sex determination is used by most mammals,[14] but also some insects,[15] and plants (Silene latifolia).[16] The X0 sex-determination is found in most arachnids, insects such as silverfish (Apterygota), dragonflies (Paleoptera) and grasshoppers (Exopterygota), and some nematodes, crustaceans, and gastropods.[17][18]
