Chicken evolution rate challenges timings of domestication and human migrationChickens are evolving faster than previously thought, according to new research that challenges ideas of when they were domesticated and may have implications for human migration.

The findings, published in journal Biology Letters, are based on a genetic analysis of a chicken population that can be traced back over 50 generations.
