Scientists Regrow Chicken Wing
An anonymous reader writes "Unlike salamanders and lizards, most animals have lost the ability to replace missing limbs. But a research team in San Diego has been able to regenerate a wing in a chick embryo — a species not known to be able to regrow limbs — suggesting the potential for such regeneration exists innately in all vertebrates, including humans." From the article: "Manipulating Wnt signaling in humans is, of course, not possible at this point, Belmonte says, but hopes that these findings may eventually offer insights into current research examining the ability of stem cells to build new human body tissues and parts. For example, he said Wnt signaling may push mature cells go back in time and 'dedifferentiate' into stem-like cells, in order to be able to then differentiate once more, producing all of the different tissues needed to build a limb."
It's possible that they never had the ability as environmental influences didn't lead to regeneration being a evolutionary edge.
:)
Lizards on the other hand probably had a different evolutionary environment where regeneration lead to an increase in survival.
Then again, I'm a business student so chances are I'm wrong
what did it taste like?

RTF: The same process that encourages regeneration also causes cancer. Cancer is such a huge problem that it counteracts the obvious advantages of long life and limb regeneration.
Once we figure out better ways to control cancer outbreaks in our cells, amazing opportunities to manipulate our bodies will become available to us.
Understanding and controlling cancer is the key to everything.
Why are you letting these clowns ruin our country?
