Sexual Reproduction
Figure 16: Male and Female Birds. Even evolutionists admit that evolution seems incompatible with sexual reproduction. For example, how could organisms evolve to the point where they could reproduce before they could reproduce?
Either this series of incredible and complementary events happened by random, evolutionary processes, or sexual reproduction was designed by intelligence.
If sexual reproduction in plants, animals, and humans is a result of evolutionary sequences, an unbelievable series of chance events must have occurred at each stage.
- The amazingly complex, radically different, yet complementary reproductive systems of the male and female must have completely and independently evolved at each stage at about the same time and place. Just a slight incompleteness in only one of the two would make both reproductive systems useless, and the organism would become extinct.
- The physical, chemical, and emotional systems of the male and female would also need to be compatible (a).
- The millions of complex products of a male reproductive system (pollen or sperm) must have an affinity for and a mechanical, chemical (b) and electrical (c) compatibility with the eggs of the female reproductive system.
- The many intricate processes occurring at the molecular level inside the fertilized egg would have to work with fantastic precision—processes scientists can describe only in a general sense (d)
- The environment of this fertilized egg, from conception through adulthood and until it also reproduced with another sexually capable adult (who also “accidentally" evolved), would have to be tightly controlled.
- This remarkable string of “accidents" must have been repeated for millions of species.
a. In humans and in all mammals, a mother’s immune system, contrary to its normal function, must learn not to attack her unborn baby—half of whom is a “foreign body" from the father. If these immune systems functioned “properly," mammals—including each of us—would not exist.

d. For example, how could meiosis evolve?
Furthermore, if sexual reproduction evolved even once, the steps by which an embryo becomes either a male or female should be similar for all animals. Actually, these steps vary among animals (e).
Evolution theory predicts nature would select asexual rather than sexual reproduction (f). But if asexual reproduction (splitting an organism into two identical organisms) evolved before sexual reproduction, how did complex sexual diversity arise—or survive?
If life evolved, why would any form of life live long beyond its reproductive age, when beneficial changes cannot be passed on? All the energy expended, supposedly over millions of years, to allow organisms to live beyond reproductive age would be a waste. In other words, why haven’t all organisms evolved reproductive systems that last a lifetime?
Finally, to produce the first life form would be one miracle. But for natural processes to produce life that immediately had the capability to reproduce itself would be a miracle on top of a miracle (g).

f. “This book is written from a conviction that the prevalence of sexual reproduction in higher plants and animals is inconsistent with current evolutionary theory." George C. Williams, Sex and Evolution (Princeton, New Jersey: Princeton University Press, 1975), p. v.
“So why is there sex? We do not have a compelling answer to the question. Despite some ingenious suggestions by orthodox Darwinians (notably G. C. Williams 1975; John Maynard Smith 1978), there is no convincing Darwinian history for the emergence of sexual reproduction. However, evolutionary theorists believe that the problem will be solved without abandoning the main Darwinian insights—just as early nineteenth-century astronomers believed that the problem of the motion of Uranus could be overcome without major modification of Newton’s celestial mechanics." Philip Kitcher, Abusing Science: The Case Against Creationism (Cambridge, Massachusetts: The MIT Press, 1982), p. 54.
“The evolution of sex is one of the major unsolved problems of biology. Even those with enough hubris to publish on the topic often freely admit that they have little idea of how sex originated or is maintained. It is enough to give heart to creationists." Michael Rose, “Slap and Tickle in the Primeval Soup," New Scientist, Vol. 112, 30 October 1986, p. 55.
“Indeed, the persistence of sex is one of the fundamental mysteries in evolutionary biology today." Gina Maranto and Shannon Brownlee, “Why Sex?" Discover, February 1984, p. 24.
“Sex is something of an embarrassment to evolutionary biologists. Textbooks understandably skirt the issue, keeping it a closely guarded secret." Kathleen McAuliffe, “Why We Have Sex," Omni, December 1983, p. 18.
“From an evolutionary viewpoint the sex differentiation is impossible to understand, as well as the structural sexual differences between the systematic categories which are sometimes immense. We know that intersexes [organisms that are partly male and partly female] within a species must be sterile. How is it, then, possible to imagine bridges between two amazingly different structural types?" Nilsson, p. 1225.
“One idea those attending the sex symposium seemed to agree on is that no one knows why sex persists." [According to evolution, it should not. W.B.] Gardiner Morse, “Why Is Sex?" Science News, Vol. 126, 8 September 1984, p. 155.
g. “In the discipline of developmental biology, creationist and mechanist concur except on just one point—a work of art, a machine or a body which can reproduce itself cannot first make itself." Pitman, p. 135.
