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 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

• liver

• appendix

The fossil record help scientists

• better understand the kinds of organisms that lived in the past

• better understand how the environment has changed over time

• better understand how organisms have evolved over time

• all of the above

NGSS.MS-LS4-2

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 forelimbs of humans, cats, whales, and bats are similar in structure due to having a common ancestor hundreds of millions of years ago. Is this considered homolgy or analogy?

• Homology

• Analogy

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

NGSS.MS-LS4-2

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
