C) In 2010, scientists excavated a skull fossil that provides evidence of a newly discovered
species of big cat. Based on the evidence, scientists hypothesize that big cats branched off
from smaller wild cats about 6 million years ago. Which of these resources did the scientists
most likely rely on to form their hypothesis? (1 point)
A food web showing feeding relationships of organisms where the fossil skull was found
Population and migration data for small wild cats living in the ecosystem where the skull was
found
The fossil record and DNA comparisons of big cats and small cats
The historical record of interactions between different species of big cats
The fossil record and DNA comparisons of big cats and small cats
D)
Natural selection is the process through which populations of living organisms adapt and
change.
An example of this is the peppered moth, which maintained it's ability to camouflage itself (hide
in it's environment) through natural selection of darker colored wings in response to a
darkening of it's environment.
Which of the following would be another example of natural selection? (MARK ALL THAT
