Many fish change from one sex to another including Clown fish


Actually, I concede that Clown fish present convincing evidence of evolution. There is a well-defined line of descent from Clown bacteria to Clown plankton to Clown fish to Clown amphibians to Clown reptiles to Clown mammals to clown Hominids to Clown humans. Even this ignorant creationist can see that.

So without the Clown fish, there would be no clowns to entertain our children and there would be no evolution scientists.

It's not a record by any means, but there are few that rise to your level of obvious, consistent, repeated and easily proveable idiocy.

[quote]All male and female mammals have mammary glands, which is the organ that produces milk. When mammary glands mature fully in females during puberty, they develop into a state where a hormonal spike—most notably of prolactin—can easily induce lactation. For males, the gland generally doesn’t mature to that level.

So the difference is a matter of hormonal influence, first during puberty and then again after pregnancy. Men do have the necessary equipment, but usually they don’t naturally produce the necessary levels of hormones to use it. Provide the right hormones, though, and male lactation is absolutely possible.[/qs]

Err, actually, you should read something about chicken and crocodile reproduction...

Actually, some unicellular organisms do have to have sex with themselves to be able to reproduce. Those organisms don't have to wear clown uniforms or paint their faces red or even blush about it. So, what's your point?
