Genesis 1:28
"Researchers in our day still admit they are baffled about the origin of sexual reproduction. Why sex exists is problematic for many reasons, such as the fact that many organisms, from dividing microbes to plants that grow from cuttings, do very well without it. The problem for evolution has always been that sexual reproduction cannot occur until both the copulatory organs are well matched, and the gametes, both the eggs and sperm, are functional so that the union of the two cells produces viable offspring. Sex is a classic case of irreducible complexity.
It is hard to even imagine the evolution from asexual to sexual reproduction, and even if one could, imagination is a far cry from demonstration. Science Daily stated recently that
There are significant gaps in our knowledge on the evolution of sex, according to a research review on sex chromosomes from Lund University in Sweden. Even after more than a century of study, researchers do not know enough about the evolution of sex chromosomes to understand how males and females emerge.Another problem is many different types of sexual systems exist in nature. Even the chromosomes that determine the sex are very diverse in living organisms. Mammals use XY (XX produces a female, XY a male) but snakes and birds use the ZW system (ZW produces a female, and ZZ a male). The Platypus has 10 sex chromosomes! Platypus sperm are either XXXXX (which produces a female) or YYYYY (which produces a male). Less studied are haploid UV sex chromosomes and
Some systems, such as those used by many reptiles and some fish, use a temperature-dependent sex determination in which the specific temperature during the thermosensitive period of embryonic or larval development determines the offspring’s sex. Some lizards even have the option of either laying eggs or reproducing by live birth.
Thus, evolutionists have to figure out how each system evolved – a huge problem if all sexually reproducing animals descended from the first single asexually reproducing organism. In spite of gallons of ink spilled in attempting to solve this question, the conclusion of Professor of Biology Graham Bell, written over 35 years ago—and 35 years is a lifetime in science—is still very accurate. He said, “Sex is the queen of problems in evolutionary biology.” One evolutionist wrote under the chapter title of “The Ultimate Existential Absurdity” that evolutionary biologists are teased for their obsession with why sex exists. “Sex is a puzzle that has not yet been solved,” Mark Ridley said; “no one knows why it exists.” CEH
