Human Evolution on Trial – Species – by Terry Toohill

This is a very interesting guest post at Remote Central:

All species vary through time and space. You don’t necessarily look the same as any one of your ancestors. Therefore “like begets like” but each individual can be a bit different. It is impossible for a sperm whale to evolve from a bowl of petunias, or a duck from a dandelion, as some creationist and Intelligent Design supporters accuse evolutionists of believing. But over time it is possible for a cow to evolve from something like a camel, or a human to evolve from something like an ape. Evolution doesn’t proceed in a straight line though, especially not a straight line with a human at the end.

  1. News to me that female ducks have Y chromosomes. Did a little looking online in the literature and could find no mention of a Y chromosome in mallards.

  2. Actually, for any given species, there is a straight line back through its ancestry. That doesn’t give the complete picture of evolution, however, and that’s what’s important.
