Evidence of Evolution

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment

• The organisms shown may have developed from a common ancestor

• The organisms shown have the same genetic diseases

• All vertebrate species have identical forelimbs

The cave fish and minnow are related to each other but the cave fish is blind and only has the remnants of an eye. What type of structure is this?

• vestigial

• analogous

What can the arm bones of humans and bats show us? That they...

• .. shared an ancestor whom had that arm structure

• ... will eventually evolve into similar creatures

• ... share a gene pool

Structures are similar in function but not in anatomical structure
EXAMPLE: bird wings vs. butterfly wings

• Vestigial

• Homologous

• Analogous Structures

• Embryonic

• exactly the same DNA sequences

• no proteins in common

• completely different DNA sequence

The study of the early stages of development that is one evidence of evolution is:

• Homologous Structures

• Embryology

• Vestigial Organs

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor

• Have very similar skeletal structures

• belong to the same species

• must range great distances to eat
