Lions and cougars are two of the eight living species of big cats. They share some major similarities, such as a flexible hyoid bone connecting the tongue to the roof the mouth. This is what enables them to roar. However, there are differences between the species. For instance, lions usually hunt in groups, a method thought to be suitable to their open savanna environment. Cougars, like most big cats, usually hunt alone. Also, lions are found throughout various parts of Africa, and cougars are found in the Americas. How does geographical distribution provide support to the theory of evolution through natural selection?
A. The similarities between lions and cougars suggest they share a common ancestor whose populations became separated over time; this separation led to separate evolution through natural selection in their distinct environments.
B The similarities between lions and cougars suggest that their environments are similar enough to have given rise to two quite similar animals, but different enough to cause subtle differences in how they evolved.
C . That lions and cougars live on different continents serves as evidence that environmental
factors have little influence on how species evolve; these two cats evolved similarly despite being exposed to different environmental factors.
D. That lions and cougars live on different continents serves as evidence that similar-looking animals living on different continents have no true relationship to each other, having evolved along completely separate paths from one another.
