evidence of evolution

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

Study of embryos of various organisms to show a common ancestor because of similarities in development

• natural selection
• embryology
• speciation
• evolution

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

Which is not evidence for evolution?

• many animals have homologous structures due to common ancestry
• Many animals have vestigial structures from an ancestor
• We can observe changes in life forms by observing the fossil record
• All of these are evidence for evolution

Which IS NOT used as evidence for evolution?

• Fossils

• Natural Selection

• Early Development/Embryos

• Body Structure/Anatomy

• DNA/Proteins

Which layer is the youngest

• 1
• 2
• 3
• 4

Which layer is the oldest

• B
• A
• E
• C

What is this an example of?

• Homologous structure

• Analogous structure

• Vestigial organs

• Functional adaption

Which of the following is an example of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the tailbone of a human
