This is the process by which species adapt to environmental changes over a long time.

• natural selection

• fossilization

• evolution

• embryology

• Fossil B is older than fossil C
• Fossils A is older than fossil B
• Fossil D is older than fossil C

How do these fossils of ancient humans provide evidence for evolution?

• The similarities between the skulls infer they may be related to each other. The differences show how these ancient humans have changed over time.

• The separation of humans and apes is an example of speciation

• The common ancestor of humans and great apes lived between 6 and 8 million years ago

• These skulls don't help provide evidence for evolution. We need more information to be sure.

A body structure that is similar in position, structure, and evolutionary origin, but not necessarily in function is

• a homologous structure

• an analogous structure

• a vestigial structure

• an adaptive structure

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment
• The organisms shown may have developed from a common ancestor
• The organisms shown have the same genetic diseases
• All vertebrate species have identical forelimbs

The similarities among homologous structures are evidence that life on Earth shares a common ancestor from which many other species have evolved over time.

• True

• False

This process is defined as when a species separates from other members of its species and develops unique characteristics.

• evolution

• speciation

• analogous

• separation

Modern organisms have some similarities to organisms that are extinct. A possible explanation for this is they are evolutionarily related to each other, possibly be a common ancestor.

• True

• False
