2. 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.
3. 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.
8. TYPE OF INDIRECT EVIDENCES
Evidence from fossil records
Evidence from structure
Evidence from embryological
development
Evidence from biochemistry
and genetic.
