What does embryology show us about evolution?

• All animals look different as embryos

• Development happens at different rates

• Similar embryos suggest common ancestry

• Embryos do not change

Why do embryonic similarities fade as development continues?

• Because cells stop dividing

• Because evolution reverses

• Because each species develops unique traits

• Because embryos don’t grow
