what are you people talking about.This is an embryonic chicken, meaning not alive, and its not like they killed it after it was already alive. It wasn't born yet, and this is a huge break-through. Think of what this could do for humans, we could have the ability to regrow bones, muscles, practically anything in the human body which is amazing. Honesty, think about what you say, before you just speak people because someday this could possibly save your life.
