• True

• False

This is a process in which species gradually change over time.

• evolution

• competition

• reproduction

• variation

The trace remains of an organism that lived long ago, most commonly preserved in sedimentary rock.

• evidence

• extinction

• fossil

• carbon dating

This is an inherited trait that helps an organism survive and reproduce in its environment.

An Analogous Structure is?

• The differences found among the individuals within the same population

• When homologous structures become used for different purposes

• Some structures evolved independently of common ancestor. These structures that have similar function due to environmental pressures but DON'T share a common ancestor.

• the study of embryos and their development

Embryology is?

• is a branching diagram or "tree" showing the inferred evolutionary relationships among various species based on DNA, Traits, & Behavior.

• A single group of organism; all from the same species

• the study of embryos and their development

• is a characteristic that helps an organism survive and reproduce in its environment
