Selection
Which pattern of evolution occurs as a result of different species adapting to the SAME environment?
Coevolution
Convergent Evolution
Macroevolution
Microevolution
Some species evolve together because their survival is dependent upon one another.
What is this pattern called?
Coevolution
Convergent evolution
Macroevolution
Microevolution
If analysis is done on amino acids of a few organisms to compare to humans and we find a lemur has two different from us while the kangaroo has eight different, which is more closely related to humans?
Lemur
Kangaroo

Evolution describes change in species over time; natural selection is the mechanism that drives evolution.
Does evolution explain the origins of the universe and of life on Earth?
Yes
No
