• Natural selection

• Fossilization

What do we call a change in a species over time?

• Adaptation

• Evolution

• Extinction

• Environmental influences

Why do embryologist study embryos?

• to see if they are related

• to understand adaptations

• to determine the age

• to learn what parents are vestigial

Two organisms that are closely related would have

• completely different DNA sequence

• exactly the same DNA sequences

• no proteins in common

• very similar DNA sequence

What is embryology?

• the age of organisms

• the earliest growth stage of development

• the oldest stage of development

• the life span of an organism
