“MIRACULOUSLY complex.” Thus the journal Science News describes a woman’s reproductive system. But an egg from a woman’s ovaries cannot produce life on its own. For this to happen, a sperm cell from the male reproductive system must combine with the nucleus of the egg. But what does the sperm do to make the egg develop? That question still puzzles scientists.

Belief in evolution gives rise to another question: If the male and the female reproductive organs evolved, how had life been proceeding before the complete formation of both?

According to the theory of evolution, human life evolved from simple microorganisms. But, unlike humans, most microorganisms come from just one parent. They reproduce on their own. How could this form of reproduction have evolved into the more complex form requiring two parents? Evolutionists find this hard to answer, as shown in the panel on the preceding page.

This big jump is glibly described as “the invention of sexual reproduction.” But some scientists have the courage to object. Professor Jaap Kies, of the University of the Western Cape, South Africa, describes it as “outrageous speculation.”

There is only one satisfying explanation for the reproduction of life. It is a gift from the all-wise Creator, Jehovah God. As the Bible says: “Every good gift and every perfect present is from above.”​—James 1:17.
