this type of evidence involves looking at organisms which are extinct
What is fossils?
Common Descent
Who was the other Scientist who worked on Natural Selection?
Alfred Wallace
When organisms in separate environments (ex: on different continents) originated from a common ancestor.
What is evolution through common descent (common ancestry)?
What is the difference between homologous structures, analogous structures and vestigial structures?
Homologous- similar structure different function
Analogous- different structure similar function
Vestigial- no function remanent from an ancestor
What are the three patterns of evolution?
Convergent (do not share common ancestor, become more similar)
Divergent (share a common ancestor, become more different)
Coevolution (2 organisms which interact in the environment cause each other to evolve)
