EVIDENCE OF EVOLUTION
Evidence of natural selection
1. ARTIFICIAL SELECTION
It is the selection by humans rather than by
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
Refers to a consistent trend over
This kind of trend might be
pigmentation, larger brain
volume, with faster-active
enzyme, a more extensive root
system, or some other traits.
PATTERNS OF ADAPTATION
a trait that promotes survival and reproduction of an
organism within a particular environment .
1. CONVERGENT EVOLUTION
It happens when similar
similar adaptations in
organisms of very different
2. DIVERGENT EVOLUTION
It happens when different
different adaptations in
closely related organisms.
