adaptions

small changes in a gene pool which alters appearance or functioning leading to adaptions to the environment (within a species)

MACRO EVOLUTION:

speciation

large changes in the gene pool occurring over long periods of time leading to the development of new groups of organisms

GENETIC DRIFT:

changes in gene frequency which occurs by chance

most noticeable in small populations

FOUNDER EFFECT:

BOTTLENECK EFFECT:
