Irreducible Complexity in Sperm Cells
Although some Darwinists try to deny it, sexual reproduction has long been a problem for evolution. In fact, it refutes evolution. The smallest of human cells are spermatozoa, and were once thought to be simple. At one time, cells were thought of as simple until scientists had better equipment and learned that they are amazingly complex.
Sperm cells were thought of as simple cells even after other cells were discovered to be fascinating. They lacked certain features found in other cells and functioned differently. Scientists had plausible reasons for thinking they were simple but that all changed quite recently.

Human sperm carries the 23 male chromosomes required to fertilize the egg in the woman’s fallopian tube. The male sperm (spermatozoon, plural spermatozoa) is the smallest cell in the human body and, for much of history, was believed to be one of the simplest human cells. Its task was also viewed as simple, namely to move paternal genes from the male to the female. To do this, the transport system was streamlined for speed and efficiency. The vast majority of sperm fail in their mission: of the billions of sperm released during the reproductive life of a human male, very few manage to fertilize an egg.
This launches the first of three somewhat technical articles.
- To finish the first one, see "Intricate Design Found in Sperm Cells."
- Next is "More Details on Sperm Design Published."
- Finally, see how sperm evolution is asserted, but as usual, nothing is demonstrated at "How DNA Is Packaged in Sperm Cells."
