Genetic Drift is important

Genetic Drift is important
A problem us evolutionary biology oriented atheists have with creationist theists is defining the evolutionary advantage of every single biological feature. The truth is: we don't have to provide a reproductive, 'fitness' advantage for every biological feature in existence because Natural Selection isn't the only mechanism that drives speciation.

Genetic Drift is overlooked when genetic drift is fair explanation for any biological feature with no apparent advantage. Genetic drift is the random chance that an allele is eliminated or reduced in a population by for example a natural disaster.

[sorry for cutting you short of explanation. Biology professor at the University of Toronto, Larry Moran has written extensively on the importance of genetic drift in evolutionary biology http://sandwalk.blogspot.com/]

Coincidentally, TFS, this article was posted today on the news section of my Archaeology board.

Quote:Using DNA to trace the evolutionary split between head and body lice, researchers conclude that body lice first came on the scene approximately 190,000 years ago. And that shift, the scientists propose, followed soon after people first began wearing clothing.


Not the most charming of subjects, I grant you!

The article may be a good example of genetic drift or speciation by 'geographic' isolation. But in the case of the lice, the isolation was athropographic haha.

Making me itch just to think about it.


Who says science is all "glory?"
