Evidence of evolution

  1. 1. EVIDENCE OF EVOLUTION Evidence of natural selection
  2. 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. 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.
  4. 4. PATTERNS OF ADAPTATION Adaptation a trait that promotes survival and reproduction of an organism within a particular environment .
  5. 5. 1. CONVERGENT EVOLUTION It happens when similar environments produce similar adaptations in organisms of very different ancestry.
  6. 6. 2. DIVERGENT EVOLUTION It happens when different environments produce different adaptations in closely related organisms.
  7. 7. EVIDENCE OF COMMON ANCESTRY
  8. 8. TYPE OF INDIRECT EVIDENCES Evidence from fossil records Evidence from structure Evidence from embryological development Evidence from biochemistry and genetic.
