Natural Selection and Mutations
n Evolution model predicts:
nSmall variations between
members of a species would
confer differing degrees of advantage or disadvantage in the struggle for existence
nThose with significant
advantages would be favored
nNew and higher types of
organisms would emerge
nA mutation (structural change
in a gene) is the source
of genetic variation
nMutations are primarily
beneficial
