A recent experiment by a man called Patrick from the University of British Columbioa shows that natural selection does accelerate speciation. It was in the wild, too not in a lab.
‘In the first experiment of its kind conducted in nature, a University of British Columbia evolutionary biologist has come up with strong evidence for one of Charles Darwin’s cornerstone ideas – adaptation to the environment accelerates the creation of new species.
“A single adaptive trait such as color could move a population towards the process of forming a new species, but adaptation in many traits may be required to actually complete the formation of an entirely new species,” says UBC post-doctoral fellow Patrik Nosil. “The more ways a population can adapt to its unique surroundings, the more likely it will ultimately diverge into a separate species.”
The assertion that natural selection does not cause speciation is a central, wobbly plank of creationist argument. This shows it demonstrably does.
Up yours, creationists. Sideways. More of the same. please.
