We completed the "Teddy Graham" natural selection experiment last night with rave reviews from the predator. While the bitter tasting "Teddy" was evolutionarily selected; in our experiment, he eventually met the same fate as the sweet tasting, extinct "Teddy". That is, consumed for dessert.
Along the same lines, there was a story this morning on NPR about a project deciphering the genome of a Neanderthal. While the Neanderthal our humans closest evolutionary relative, and the two species co-existed, the humans were naturally selected and the Neanderthals became extinct about 30,000 years ago.
