A biologist analyzes the DNA sequences in three different primates. The biologist finds that primates A and B have almost identical DNA sequences. The DNA sequences in primate C are significantly different from those of primates A and B. This information allows the biologist to conclude that:

Answer 1

Answer) A biologist analyzes the DNA sequences in three different primates. The biologist finds that primates A and B have almost identical DNA sequences. The DNA sequences in primate C are significantly different from those of primates A and B. This information allows the biologist to conclude that:

primates A and B are more closely related to each other than either A or B is to primate C.

By looking at the similarities in the DNA sequences or amino acids, biologist can tell which species are more closely related and can also tell which of the species share a more recent common ancestor.

Hope this helps, please do the thumbs up. Thanks in advance. Have a great day ahead.
