Stupid question—with a self-evident answer, right? The information used by the organism to produce these traits is stored on a complex molecule known as DNA. [RETURN TO TEXT], [17] Cartwright, John, Evolution and Human Behavior, Macmillan, London, p. 96, 2000. As the evolutionary approach is a biological one, it suggests that aspects of human behavior have been coded by our genes because they were or are adaptive. The point of the question is this. The first sexual beings to emerge perhaps 2.5 billion years ago were what biologists call isogamous — which is a little like being gay, except everyone is somewhere between male and female. Research shows that females and males – including girls and boys, as well as women and men – have many psychological differences. A single parent is all that is required. [RETURN TO TEXT], [34] Mayr, Ernst, What Evolution Is, Basic Books, New York, p. 98, 2001. Evolutionary theorists ask us to believe that random, chance occurrences brought about this marvelously interdependent process of, first, splitting the genetic information into equal halves, and, second, recombining it through sexual reproduction. According to Margulis and Sagan, bacteria “evolved” in such a fashion as to ultimately be responsible for sexual reproduction. starfish and salamanders) to replace injured or lost parts. 2. [12] Williams’ idea was that sexual reproduction introduced genetic variety in order to enable genes to survive in changing or novel environments. In his 2001 book, The Cooperative Gene, evolutionist Mark Ridley wrote (under the chapter title of “The Ultimate Existential Absurdity”): In an article in Bioscience on “How Did Sex Come About?,” Julie Schecter remarked: This “mystery” of sex deserves serious consideration in light of its “widespread” prevalence today. The evolution of sex (and its accompanying reproductive capability) is not a favorite topic of discussion in most evolutionary circles, because no matter how many theories evolutionists conjure up (and there are several), they still must surmount the enormous hurdle of explaining the origin of the first fully functional female and the first fully functional male necessary to begin the process. Evolution by sexual selection is an idea that goes back to Charles Darwin. While at Texas A&M, he served as Coordinator of the Cooperative Education Program in Biomedical Science. An evolutionary interpretation of the effect of gender and sexual orientation on human mate selection preferences, as indicated by an analysis of personal advertisements. Evolution is the change in a population's inherited characteristics, or traits, from generation to generation. [RETURN TO TEXT], [22] Cartwright, John, Ref. 48-49, 2001. The famous Stanford University geneticist, Luigi Cavalli-Sforza (who is the head of the International Human Genome Project), addressed this fact when he wrote: In addressing the complete ineffectiveness of mutations as an alleged evolutionary mechanism, Dr. Grass� observed: Grass� is not the only prominent evolutionist to take such a view in regard to mutations as an ineffectual driving force for evolution. // -->. Yet if that is the case, why, then, have the bacteria themselves remained virtually unchanged—from an evolutionary viewpoint—for billions of years of Earth history? Evolutionists suggest otherwise. [RETURN TO TEXT], [26] Ridley, Mark, Ref. J.F. Gender stratification occurs when gender differences give men greater privilege and power over women, transgender and gender-non-conforming people. As Zimmer described it: The Tangled Bank Hypothesis, however, also has fallen on hard times. C. Rasa and E. Voland, Chapman and Hall, London, p. 4, 1989. Beneficial mutations (viz., those that provide additional information for, and instructions to, the organism) are indeed “rather rare.” Furthermore, as evolutionists have been known to admit quite candidly, mutations that affect the phenotype almost always are harmful (see Crow[37]; Cartwright[38]). But how did a process as incredibly complex as meiosis ever get started in the first place? 5, p. 60. Yet, as these theories valiantly attempt to explain why sex exists now, they do not explain the origin of sex. Cracraft, Phylogenetic Patterns and the Evolutionary Process: Method and Theory in Comparative Biology, Columbia Universiy Press, New York, p.102, 1980. This difference, a new study from the University of Texas at Austin finds, may be rooted in evolution. [For an excellent, up-to-date description of the complicated, two-part process by which meiosis occurs, see Mayr[42]] Once meiosis has taken place. And, in fact, evidence is beginning to mount that perhaps the DNA Repair Hypothesis is itself in need of “repair.” As Maddox noted: We must not overlook an important fact throughout all of this: These theories valiantly attempt to explain why sex exists now, but they do not explain the origin of sex. At conception, the chromosomes inherited from the sperm are paired with the chromosomes inherited from the egg to give the new organism its full chromosomal complement. Evolution and Gender. This apparent mismatch of biological sex and gender identity can lead to severe gender dysphoria. They claim that the maintenance of sex is therefore a “nonscientific” question that “leads to intellectual mischief and confusion.”[6] This implies, however, that sex is useless, and that it has been retained through the years merely by accident. 155-157, 1979. Evolutionary biology is unable to reveal why animals would abandon asexual reproduction in favor of more costly and inefficient sexual reproduction. [RETURN TO TEXT], [10] Crow, Ref. The unwieldy tail on the male peacock, for … Cultural diversity created measures of diversity that were independent of race or gender (for example, life experiences, socio-economic background, language proficiencies, and more) and therefore could benefit all employees, which includes white males. In addressing this very issue, Maddox asked quizzically: Exactly our point! And, further, how is it that these gametes (eggs and sperm) conveniently “evolved” so that they each contain half the normal chromosome number of somatic (body) cells? Evolutionists freely admit that the origin of the sexual process remains one of the most difficult problems in biology. Asexual reproduction thus does not require one egg-producing parent and one sperm-producing parent. They propagate as your cells divide and, in animals, pass from mothers to offspring through eggs. Evolutionists believe that the driving forces behind evolution are natural selection and genetic mutations occurring over lengthy spans of geologic time (see Peter Ward[33]). The Tangled Bank Hypothesis suggests that sex evolved in order to prepare offspring for the complicated world around them. iology texts illustrate amoebas evolving into intermediate organisms, which then give rise to amphibians, reptiles, mammals, and, eventually, humans. Sporulation (the formation of spores) is one method of asexual reproduction among protozoa and certain plants. And how can evolution (via natural selection) explain it? 14, p. 97. He also is a graduate of Texas A&M University, where he earned both M.S. Why is this the case? Not only is an intricate process required to produce a sperm or egg cell in the first place via meiosis, but another equally intricate mechanism also is required to rejoin the genetic information during fertilization in order to produce the zygote, which will become the embryo, which will become the fetus, which eventually will become the newborn.

Don’t the asexual organisms ever “need” genetic variety in order to enable genes to survive in changing or novel environments (the Lottery Principle)? That is to say, they constantly have to “run to try to improve” (and the development of sex would be one way of accomplishing that). From an evolutionary perspective, it is beneficial … Oddly, however, most sexual beings have just two sexes — the loneliest number when it comes to finding a mate. Freeman, San Francisco, CA, p. 391, 1977. Evolution is dependent on change (the English word “evolution” derives from the Latin evolvere, meaning “to unroll, to change”). 14, p. 99. 1.

One way to prevent such a spread is to avoid mixing mitochondria when you have sex. When pressed to answer questions such as, “Where did males and females actually come from?,” “What is the evolutionary origin of sex?,” evolutionists become silent.

In essence, this means examining the differing reproductive challenges faced by the sexes throughout our species’ history, and linking these with psychological and behavioural characteristics. monthName[5] = 'June' [Somatic cells reproduce via the process of mitosis, which maintains the species’ standard chromosome number; gametes are produced via the process of meiosis, which halves that number.

At some point authors must be questioned as to the rationale in their thinking? One leading theory goes back to the bizarre nature of certain machinery we all carry around in our cells — little engines known as mitochondria that help convert food to energy. Quite obviously, if everything remained the same, there would be no evolution. and Ph.D. degrees in microbiology. In his book, Evolution of Living Organisms, the eminent French zoologist, Pierre-Paul Grass�, raised this very point. It is our contention, based on the evidence, that the intricacy, complexity, and informational content associated with sexual reproduction demand the conclusion that sex is neither a “historical accident” resulting in evolutionary baggage, nor a product of organic evolution itself, but rather is the product of an intelligent Creator. 88,103,107. As they have struggled to explain the existence of sexual reproduction in nature, evolutionists have suggested four different (and sometimes contradictory) theories, known in the literature as: (1) the Lottery Principle; (2) the Tangled Bank Hypothesis; (3) the Red Queen Hypothesis; and (4) the DNA Repair Hypothesis.

That way you only get them from your mother. It suggests that sex would be favored by a variable environment, yet a close inspection of the global distribution of sex reveals that where environments are stable (such as in the tropics), sexual reproduction is most common.

[RETURN TO TEXT], [15] Reichenbach, Bruce and V. Elving Anderson, On Behalf of God, Eerdmans, Grand Rapids, MI, p. 18. Differences in sexual behaviour between men and women can be explained by looking at the different roles in child bearing and raising. A central claim of evolutionary psychology is that the brain (and therefore the mind) evolved to solve problems encountered by our hunter-gatherer ancestors during the upper Pleistocene period over 10,000 years ago. Jealousy seems to be an unique emotion among other negative emotions. The biological approach's explanation for why men and women are different. monthName[2] = 'March' There is the added problem related to the two different types of cell division we mentioned earlier-mitosis and meiosis. He was an invited speaker to the 2003 International Conference on Creationism. Lewis Thomas, the highly regarded medical doctor who served for many years as the president and chancellor of the prestigious Sloan-Kettering Cancer Center in Manhattan, was unable to contain either his enthusiasm or his praise for the system we know as “sexual reproduction.” In his book, The Medusa and the Snail, he wrote about the “miracle” of how one sperm cell forms with one egg cell to produce the cell we know as a zygote, which, nine months later, will become a newborn human being. ANSWER: There are two key aspects about sex that are contrary to the notion of evolution. The Red Queen Hypothesis was first suggested by Leigh Van Valen in an article titled “A New Evolutionary Law” in Evolutionary Theory. [RETURN TO TEXT], [29] Ridley, Ref. Niles Eldridge, a staunch evolutionist from the American Museum of Natural History, has declared: “Sex occurs in all major groups of life.”[7]. With all due respect, there is not an evolutionist on the planet who has been able to come up with an adequate (much less believable) explanation as to how somatic cells reproduce by mitosis (thereby maintaining the species’ standard chromosome number in each cell), while gametes are produced by meiosis—wherein that chromosome number is halved so that, at the union of the male and female gametes during reproduction, the standard number is reinstated. Key studies and research and their conclusions about gender development. What scientists find puzzling is that most of them still use a system of two sexes — in their case plus and minus rather than male and female. a kind of “accidental holdover” from the era of single-celled organisms. The origin and maintenance of sex and recombination is not easily explained by natural selection. In fact, quite the opposite would be true. Nothing, in an evolutionary sense, forces organisms to reproduce sexually”[29] [emp. Hardman supplied a set of suggested letters for teachers, and Richardson supplied her full course syllabus. How could nature evolve a female member of a species that produces eggs and is internally equipped to nourish a growing embryo, while at the same time evolving a male member that produces motile sperm cells? But how do evolutionists explain this? [RETURN TO TEXT], [12] Williams, George C., Sex and Evolution: in the Monographs in Population Biology series, Princeton University Press, Princeton, NJ, 1975. So to keep mitochondria in check many organisms kill the ones from their mates. To appreciate this, compare a sexually reproducing female with one that reproduces asexually. These new unfriendly mitochondria could start to spread through the human population at our expense. Yet doing so provides no automatic guarantee of winning the struggle known as “survival of the fittest.” “Nature,” said the eminent British poet Lord Tennyson, is “red in tooth and claw.” Currently, the Red Queen Hypothesis seems to be the favorite of evolutionists worldwide in attempting to explain the reason as to the “why” of sex. As Cartwright put it: But, as Cartwright went on to admit: “This theory is not without its problems and critics.”[25] One of those problems, expressed by Mark Ridley (no kin to Matt), is: “We do not know for sure that sex exists to purge bad genes.”[26] No, we certainly do not! '0':'')+lm_month; During mitosis, all of the chromosomes are copied and passed on from the parent cell to the daughter cells. Sexual selection theory helped Darwin explain many traits, especially in males, that otherwise seemed maladaptive. Evolutionists have practically been forced to concede that there must be “some advantage” to a system as physiologically and energetically complex as sex-as Mark Ridley admitted when he wrote: “...[I]t is highly likely that sex has some advantage, and that the advantage is big. Yet, we never learn exactly when or how independent male and female sexes originated. Michod and Levin, Sinauer Associates, Sunderland, MA, p. 35, 1988. Let's Continue The Evolution . Albert Einstein said it well when he stated: “God does not play dice with the universe.”[49], [1] Bell, Graham, The Masterpiece of Nature: The Evolution and Genetics of Sexuality, University of California Press, Berkeley, CA, p. 19, 1982. 31, p. 103. Somewhere along this evolutionary path, both males and females were required in order to ensure the procreation that was necessary to further the existence of a particular species. Why restrict our options? It is one thing to develop a theory or hypothesis to explain something that already exists, but it is entirely another to develop a theory or hypothesis to explain why that something (in this case, sex) does exist. lm_month=a.getMonth()+1;lm_month=((lm_month<10)? [RETURN TO TEXT], [30] Cartwright, John, Ref. Isogamous algae, on the other hand, still have sex but instead of mixing sperm and eggs they mingle sex cells of roughly the same size — generically known as gametes. Currently, Dr. Thompson is the Executive Director of Apologetics Press and editor of Reason & Revelation. 3, p. 254. When asked whether the future of gender was evolution and extinction, Barker, Nyong’o, Wallace and Bornstein all said they hoped for extinction. That’s not a big problem for us, since males simply shed most of their mitochondria when they make sperm. The “tangled bank” phraseology comes from the last paragraph of Darwin’s Origin of Species, in which he referred to a wide assortment of creatures all competing for light and food on a “tangled bank.” According to this concept, in any environment where there exists intense competition for space, food, and other resources, a premium is placed on diversification. But we would suggest that there is no naturalistic explanation at all for the origin or maintenance of sex. He currently serves as the Director of Scientific Information at Apologetics Press, and as associate editor of Reason & Revelation. Sexual reproduction requires organisms first to produce, and then maintain, gametes (reproductive cells-i.e., sperm and eggs). Five forces can cause genetic variation and evolution in a population: mutations, natural selection, genetic drift, genetic hitchhiking, and gene flow. Richardson’s course, “HS 138: Sex, Gender, and Evolution,” which she began offering in the spring, forms the core of the website. [RETURN TO TEXT], [13] Zimmer, Carl, Parasite Rex, The Free Press, New York, p. 163, 2000. Evolutionists adhere to the view that the first organisms on Earth were asexual, and thus they believe that, during billions of years of Earth history, asexual organisms experienced numerous beneficial mutations that caused them to evolve into sexual organisms. To understand life before the advent of males and females, you need a universal definition … The origin and maintenance of sex and recombination is not easily explained by natural selection. There will always be differences between men and women. [RETURN TO TEXT], [16] Zimmer, Carl, Ref. Feedback | It is little wonder that, in their more candid moments, evolutionists admit, as Ackerman eventually did, that “when it comes to sex, we inhabit a mystery.”[47].

[RETURN TO TEXT], [28] Maddox, Ref. Why, then, does sex exist? Gender roles, as an example, exist solely because society as a whole chooses to accept them, but they are perpetuated by the media. Home | As Carl Zimmer wrote under the title of “Evolution from Within” in his volume, Parasite Rex: “A line of clones might do well enough in a forest, but what if that forest changed over a few centuries to a prairie? Sex would not have evolved, and been retained, unless it had some advantage”[8] (emp. As they move into adulthood, nearly half of these children (or even … To understand life before the advent of males and females, you need a universal definition of each: Males produce a smaller sex cell (sperm or pollen) than their female counterparts. But if you’re isogamous, you’re exchanging same-sized gametes instead of sperm and eggs. According to scientists, the very first organisms to dare engage in sex were more like Adam and Steve than Adam and Eve. Additionally, it should be noted that today we still see organisms that reproduce asexually, as well as organisms that reproduce sexually—which raises the obvious question: Why do some organisms continue to reproduce asexually, while others have “evolved” the ability to reproduce sexually? [RETURN TO TEXT], [48] Thomas, Lewis, The Medusa and the Snail, Viking, New York, pp. But why is this the case? 6, p. 252. First is the waste of resources in producing males. Regeneration is another form of asexual reproduction that allows organisms (e.g. Bonnie G. Smith. It states men have evolved a greater desire to have causal sex in order to produce as many offspring as possible to pass on their genes. Is sex the product of a historical accident or the product of an intelligent Creator? The theory of evolution proposes that life and humans arose through a natural process. [RETURN TO TEXT], [36] Mayr, Ernst, Ref. Don’t they ever “need” to prepare their offspring for the complicated world around them (the Tangled Bank Hypothesis)? This claims gender role behaviours are related to ensuring the survival of ones genes. If you haven't read Roughgarden's "Evolution's Rainbow" yet, you should. A spore is a reproductive cell that produces a new organism without fertilization. Many organisms, including some fungi, algae and single-celled pond-swimmers, still practice isogamy. Some organisms do expand their sexual options by having many sexes — 100 for some pond-swimming protozoans. lm_year=a.getYear();lm_year=((lm_year<1000)? How can “old” people produce “young” babies? Mushrooms use 30,000 and can mate with any but their own. Exactly how did we arrive at two separate genders-each with its own physiology? Such pickiness is an enormous paradox, says Laurence Hurst, a biologist at the University of Bath in England. 3, pp. [RETURN TO TEXT], [20] Cartwright, John, Ref. How does the theory of evolution explain the formation of genders within most species? [RETURN TO TEXT], [38] Cartwright, John, Ref. Perhaps Cartwright summarized the issue well when he said: “There is perhaps no single explanation for the maintenance of sex in the face of severe cost.”[30] Since he is speaking of a strictly naturalistic explanation, we would agree wholeheartedly. The current article reviews some of the current theories for why sexual reproduction exists today.

Deleterious mutations “will be selected against and will be eliminated in due time.”[35] That, then, leaves beneficial mutations, which, according to evolutionists, are incorporated into the species by natural selection, eventually resulting in new and different organisms. Some young boys show an early preference for dressing and behaving as girls; some young girls are convinced they should be boys. Ernst Mayr, who undeniably ranks as the most eminent evolutionary taxonomist in the world, remarked in his book, What Evolution Is: “Any mutation that induces changes in the phenotype [the outward, physical make-up of an organism-BT/BH] will either be favored or discriminated against by natural selection....

Sexual reproduction, on the other hand, would be like purchasing a small number of tickets, but giving each of them a different number. Margulis and Sagan, for example, wrote: These two evolutionists have admitted that meiosis is critical for sexual reproduction. Meiosis (from the Greek meaning to split), on the other hand, occurs only in sex cells (i.e., eggs and sperm); during this type of replication, only half of the chromosomal material is copied and passed on.
