Background
It is interesting to think about why some humans have evolved to not taste bitter tastes. For decades scientists believed that some humans and chimpanzees share this trait as they had inherited it from common ancestors before the two species diverged in evolution. However recent genetic evidence has shown that both humans and chimpanzees have undergone independent evolutionary processes that have resulted in this shared trait.
This new evidence exemplifies Darwin’s theory: selection pressures have acted on both species, and each has adapted accordingly. In this case, the adaptation (inability to taste) has occurred via independent routes through a process known as convergent evolution.
