EVIDENCE OF EVOLUTION
Evidence of natural selection
1. ARTIFICIAL SELECTION
 It is the selection by humans rather than by
nature.
 The effects of artificial selection in laboratory
population have been proven by biologists.
 The only difference of the artificial selection
from natural selection is that humans decide
which individuals leave more copies of their
genes, as offspring, to the next generation
rather than the local government.
2. DIRECT OBSERVATION
 Directional selection
Refers to a consistent trend over
time.
This kind of trend might be
concerning darker
pigmentation, larger brain
volume, with faster-active
enzyme, a more extensive root
system, or some other traits.
PATTERNS OF ADAPTATION
Adaptation
a trait that promotes survival and reproduction of an
organism within a particular environment .
1. CONVERGENT EVOLUTION
It happens when similar
environments produce
similar adaptations in
organisms of very different
ancestry.
2. DIVERGENT EVOLUTION
It happens when different
environments produce
different adaptations in
closely related organisms.
EVIDENCE OF COMMON ANCESTRY
TYPE OF INDIRECT EVIDENCES
Evidence from fossil records
Evidence from structure
Evidence from embryological
development
Evidence from biochemistry
and genetic.
