simple forms
change in genes
takes many generations
greater selective advantage
greater diversity
in the DNA
new alleles in population
in both populations
through flow or movement
of genes
different allele frequencies
from one population
to another
from migration of individuals
of homozygous in a population
dosent affect
alleles frequencies
based on phenotype
for mates
through visual display
through combat
you forgot to state that the gradual change in allele frequencies may lead to speciation.

better suited survive
reproduce other populations
than others
some produce
more offspring than others

chronological order of rock layers

Subtopic
this is the risk of using images that you don't add to this yourself. this one is missing.
oldest fossil in deepest layer
Earth's continents large land mass

organisms split up
fossils dated/found

with same age
of species populations
factors determine those patterns
evolved in one location
biogeography suppots hypothesis
