- 1. Multiple Choice
Scientists have found evidence that about 2.4 million years ago a gene regulating jaw muscles mutated and may have led to the more graceful human jaw we see today. The diagram below shows the skulls of 3 hominid species. Which statement below most closely explains the link between jaw size and hominid evolution?
The jaws of hominids evolved to be smaller and less protruding over time as did the skull.
The jaws of hominids evolved to be larger and more protruding over time.
There appears to be no change in the jaws of hominids over time.
The jaws of hominids changed over time due to a change in brain size
- 2. Multiple Choice
Based on the illustration to the right, what do the similarities between human and chimpanzee hands and feet suggest about the different organisms?
Chimpanzees and humans both have hands and feet adapted for walking upright, showing they have identical DNA.
Chimpanzees and humans both have similar hands for grasping, proving they make and use complex tools.
Humans and chimpanzees both developed five digits on their hands and feet, suggesting they have a common ancestor.
Humans and chimpanzees both have thumbs, proving they eat similar foods like meat, nuts, and vegetation.
- 3. Multiple Choice
The ability to walk upright on two legs is called:
bipedalism
quadropedalism
bicyclepedalism
tripedalism
- 4. Multiple ChoiceWhich of the following correctly summarizes the physical changes that early humans went through over the past million years or so?Brain size increased as jaw size decreasedBrain size decreased as jaw size increasedBipedalism increased as use of tools increasedBipedalism decreased as the use of tools increased

- 6. Multiple Choice
What advantage did the development of bipedalism most likely confer to early hominids?
It allowed them to evolve a complex social structure
It allowed them to move and hold objects at the same time
It allowed them to evolve an opposable thumb
It allowed them to see with binocular vision
- 7. Multiple Choice
What is is the study of how and why plants and animals live where they do?
Evolution
Adaptive Radiation
Biogeography
Biogeology
- 8. Multiple Choice
Occurs when two populations of organisms form a specialized relationship and thus change in response to each other
Convergent Evolution
Punctuated equilibrium
Coevolution
Speciation
- 9. Multiple Choice
similar structures (but different functions) that suggest evidence of common ancestry
Analogous structues
Homologous structures
Vestigial structures
Natural Selection
- 10. Multiple Choice
When comparing the DNA of two different organisms, the more differences in the DNA base pairs the more-
Closely related they are.
Distantly related they are.
It doesn't prove anything.
They look alike.
- 11. Multiple Choice
What type of evidence is shown with the diagram above?
Molecular
Anatomical
Embryology
Fossil
- 12. Multiple Choice
When two organisms, such as predator and prey, evolve in response to one another
convergent evolution
divergent evolution
coevolution
gradualism
- 13. Multiple Choice
The study of where living things are/were located in the world
embryology
biochemistry
environmental science
biogeography
- 14. Multiple Choice
Fossils of felines were found on opposite sides of a mountain range. The fossils are from species that are similar anatomically, but the climates were vastly different on each side of the range. Which type of evidence for evolution do these fossils exemplify?
vestigial structures
analogous structures
coevolution
biogeography
- 15. Multiple Choice
Since the beginning, the theory of evolution has been up for debate. Those against the theory show gaps in the fossil record to discredit the theory. Which is the best counterargument as to why the fossil record can be relied upon to support evolution?
it provides evidence that extinct species are genetically identical to current species.
it provides evidence of many different types of organisms, since most species fossilize well.
it provides evidence that extinct species only fossilized during certain geologic eras.
it provides evidence of many transitional organisms that show relationships between species.
- 16. Multiple Choice
How does the fossil record provide evidence for evolution?
Finding the age of fossils (through radioactive dating) shows the earth is very old - showing there was enough time for natural selection to occur
Similar fossils can be found on different continents, thus showing the continents were connected once and thus showing how species changed as their environments changed when the continents moved
Some fossils show species that show the transition from one known ancestor to a known modern day species
Fossil don't provide evidence for evolution.
- 17. Multiple Choice
Why are similar fossils found all over the world?
The animals swam to new parts of the world before going extinct
The land masses were once connected
The organisms were transported to different areas of the world
They are not similar fossils.
