October 18, 2011 Young genes that appeared since the primate branch split from other mammal species are expressed in unique structures of the developing human brain, a new analysis finds. The correlation suggests that scientists studying the evolution of the human brain should look to genes considered recent by evolutionary standards and early stages of brain development.
PLAINFIELD, Ind. (AP) – The Associated Press declared Secretary of State Todd Rokita as the winner in the state’s 4th District race.

When a zebra finch hears a new song from a member of its own species, the experience changes gene expression in its brain in unexpected ways, researchers report. The sequential…
