Evidence of Evolution

What is this an example of? They all do different functions, swim, run, walk. But have same structure of bones

• vestigial structures

• embryology

• homologous structures

• fossil record

Which layer is the oldest?

• 1
• 2
• 3
• 4

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

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

• Homologous Structures
• Embryology
• Vestigial Organs

The similarities of the bones in the diagram provide evidence that--- (Homologous structures - Same Structure, but different functions)

• 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

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

• embryology

What is this an example of? Same Function (Job) but different structure)

• Homologous structure

• Analogous structure

• Vestigial organs

• Functional adaption

Which of the following is an example of a vestigial structure? A body part that used to be used but no longer is.

• the wings of a red-tailed hawk

• the hind limbs of a house cat

• the fins of sharks

• the tailbone of a human

What conclusions can be made based on this table shown? Compare the DNA of each animal

• the American black bear and the giant panda are most closely related

• the giant panda and the red panda are most closely related

• the red panda and the racoon are the most closely related

• the giant panda and the racoon are most closely related

The bones in the figure above are-

• Evidence of a common ancestor

• Evidence that animals can walk

• Evidence that fossils are old

• Evidence of nothing
