Change in a species over time; process of biological change by which descendants come to differ from their ancestors

Evolution

1

Group of organisms so similar to one another that they can breed and produce fertile offspring

Species

2

Trace of an organism from the past

Fossil

3

Theory that states that natural disasters such as floods and volcanic eruptions shaped the Earth's landforms and caused extinction of some species

Catastrophism

4

Principle that states that the change in landforms result from slow changes over a long period of time

6

Differences in physical traits of an individual from the group to which it belongs

Variation

8

Process by which humans modify a species by breeding it for certain traits

Artificial selection

Body part that is similar in structure on different organisms but performs different functions

Homologous structure

15

Body part that is similar in functions as a body part of another organism but is structurally different
