I remember seeing an article some time ago about the population in an African village who have evolved having two fingers and a thumb on each hand. Was this a fact or a hoax.

However, you will see from the links that it is not the whole village or tribe but a few individuals in the community. Its a genetically inherited trait so no wonder that a few related individuals have it. Arguments exist that it offers some advantage to these individuals in climbing but this has not been properly examined.

Hey the wiki article is really really good.
why do these people persist and not just die out ? we are told that tree cliimbing may be better in the Vadoma, in other words that is the Darwinian advantage, however the next article goes on to discuss the Founder Effect - which is when there is something that is just catastrophic - like Tay Sacks disease or Porphyria in SOuth Africa or Ellis van Crefeld syndrome in aborigines, which stillhangs around even so it obvioulsy gives no advantage at all.
and one of the reasons given is....if your population is less than ten to the five, the genetics of large numbers may not apply
thank you thank you
tracking down these articles is very hard....and along term suck
