DNA HOMOLOGY
study of fossil remains
Paleontology
the remainsof organisms from the past and undergo preservation (in form of rocks and ice)
fossil
Earth was a single large mass (Pangea)
land mass splits up slowly (continental drifts)
Geographical distribution
The study of biological structures in different organisms
Comparative Anatomy
structures of different
species that have similar
internal framework,
position and embryonic
development.
Homologous structure
structures of
unrelated species that
have the same function
Analogous structures
body parts of
organisms that
diminished in size as
they are nolonger
needed.
Vestigial structures
comparing the biochemistry of
different organisms
Biochemistry
most embryos of vertebrate are alike.
