1. MECHANISMS OF
EVOLUTION

2. OBJECTIVE
S
After going through with this unit, you are expected to:
1. Explain the mechanisms that produce change in
populations from generation to generation (e.g.,
artificial selection, natural selection, genetic drift,
mutation, recombination)

12. DEVELOPS IN A LONG
PERIOD OF TIME
ADAPT TO CHANGES IN
THEIR ENVIRONMENT

14. 350 BCE
Species are identical. They
tend to remain the same
species and can be arranged
hierarchically

15. AD
1749
As species change, they
migrate to another
environment resulting in their
distribution

16. 1974
Species evolved from one
common ancestor

17. 1809
Species evolved from an existing
species through environmental
forces. Traits can be passed to
thee next generations

18. 1830
All changes in the
environment are uniform
and gradual

19. 1859
Species evolved from the
process of natural selection
which cause variations within
the population
