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? * A-Population and migration data for small wild cats living in the ecosystem where the skull was found
B-A food web showing feeding relationships of organisms where the fossil skull was found
C-The fossil record and DNA comparisons of big cats and small cats
D-The historical record of interactions between different species of big cats
