17.4 Evidence of Evolution

17.4 Evidence of Evolution

Biogeography

• Closely related by different

• Diverge from a common ancestor but different environments, competition, predators, mutations make different adaptations

• Distantly related but similar

• Converge from a distant ancestor but similar environments lead to similar adaptations

Multiple Choice

• Convergent Evolution

• Acquired Traits

• Embryology

• Biogeography

Multiple Choice

• Law of Superposition

• Evolutionary Arms Race

• Divergent Evolution

• Convergent Evolution

Multiple Choice

The three species pictured do not share a common ancestor, yet have evolved to have a similar anatomy and life style. This is an example of ?

Old Earth Fossils

• Earth is ~ 4.5 billion years old

• Enough time for change through natural selection

• Fossils are tough to form and hard to find

• Fossil records show descent from a common ancestor

Multiple Choice

Which of the following can be learned by using the fossil record?

• When organisms changed or evolved

• when organisms appeared on Earth

• when organisms became extinct

• All the above

Multiple Choice

The millions of fossils that scientists have collected are called

• The Geologic Time Scale
• The Origin of Species
• The Fossil Record
• A really neat fossil collection

Multiple Choice

If scientists found this fossil, what could they infer?

• what fish are like today

• that this fish lacked oxygen

• that water once covered the area where this fossil was found

Multiple Choice

Comparing Anatomy

• Homologous-Diverge from a common ancestor (Arm/hands)

• Shows descent with modification

• Analogous-Converge from a distant ancestor(Wing of bee/bat)

• Vestigial-Structure still present but has no purpose (Snake limb)

Multiple Choice
