Evidence for Evolution

According to evolutionary theory, all living things have a common

• Purpose

• Function

• Ancestor

• Phone Number

A change in the inherited characteristics or traits of a population of species over time is ________

• evolution.

• development.

• growth.

• natural selection.

What is the study of the similarities and differences in unborn fetuses or developing organisms?

• Paleontology

• Comparative embryology

• Cosmology

• Archelogy

How does embryology support the Evolution of species over time?

• It shows that they have a common ancestor because of their similarities earlier on in development.

• It shows that they lived in the same environment.

• It does not give evidence for the evolution of species.

What type of evidence are shown in the picture above?

• Fossils

• Embryology

• Homologous Structures

• Vestigial Structures

Because whales have a pelvis and femurs, it shows whales are descended from an ancestor that was able to _____________________.

• walk

• sing

• swim

• polka

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years

• Fossils show that some species have gone extinct

• Fossils show how life forms present today are different than those from the past

• Different sedimentary rock layers provide evidence for how the environment has changed over time

What type of evidence is represented in the picture above:

• Fossils

• Vestigial Structures

• DNA

• Homologous Structures

If modern organisms have a lot of homologous structures, what inference might paleontologists make about those organisms?

• They are reptiles

• One organism evolved from the other.

• The organisms have a common ancestor.

• There is nothing to infer.

According to this data, the unknown bacterial species is most closely related to:

• Species I

• Species II

• Species III

• Species IV
