When comparing the gene coding for cytochrome c in several species, it was noted that humans and chimpanzees share the identical amino acid sequence. This means that ____.
A)humans and chimpanzees can mate and produce viable offspring
B)humans evolved from chimpanzees
C)over time, chimpanzees will eventually evolve into primitive humans
D)humans and chimpanzees are closely related in evolutionary time
E)chimpanzees will eventually evolve to become human

When comparing the gene coding for cytochrome c in several species, it was noted that humans and chimpanzees share the identical amino acid sequence. This means that ____. ​
A)humans and chimpanzees can mate and produce viable offspring
B)humans evolved from chimpanzees
C)over time, chimpanzees will eventually evolve into primitive humans
D)humans and chimpanzees are closely related in evolutionary time
E)chimpanzees will eventually evolve to become human

Quizplus · Accepted Answer

The fact that humans and chimpanzees share the identical amino acid sequence in the gene coding for cytochrome c suggests that they are closely related in evolutionary time. This supports the idea of a common ancestor for both species, rather than humans evolving from chimpanzees or vice versa. It does not necessarily mean that they can mate and produce viable offspring, or that chimpanzees will eventually evolve to become human.
