Fossils

Back 2

preserved bones or other trace of an ancient skeleton

Adaptation

Back 5

evolution of traits that makes the organism better suited for their environment

Natural Selection

Back 7

process in nature that results in survivial of the fittest

Back 31

formation of new species brought about by genetic change that prevent breeding new different groups

Front 32

gradualism

Back 32

theory that evolution occurs slowly and steadily over long periods of time

Front 33

Puncuated Equilibrium

Back 33

pattern of long periods of stability that are interrupted by episodes of rapid change

Front 34

adaptive radiation

Back 34

pattern of evolution, where selection/adaptation lead to a new form of species in a short period of time

convergent evolution

Back 35

when unrelated species independently form similar characteristics when adapting to similar environments
