Evolution

By Jodi Edge

analyze and evaluate how evidence of common ancestry among groups is provided by the

fossil record, biogeography, and homologies, including anatomical, molecular, and developmental

​and

​examine scientific explanations of abrupt appearance and stasis in the fossil record

​

Theory of Evolution

• Change happens gradually over time

• Change happens to populations, not individuals.​

• Genetic commonalities can identify common ancestry.

The theory says:

​

• ​Fossil record

• Biogeography

• ​Homologies

  • anatomical

  • molecular

  • developmental

Evidence for the theory:

• Fossils are laid down in layers from least complex to most complex.

Fossil Record:

​

Fossils from separated continents match where theory of pangea puts the continents together.

Biogeography

Simmilarities in Genetics, development, and anatomy

Homologies
