B. Chimpanzees and humans live in the same time period.

C. Chimpanzees and humans eat fruit, meat, and vegetation

Please help ?

Answer 1

I think A. Several organism shares a variety of characteristics to others but the actual identification can be done on the basis of comparison of DNA.

Answer 2

B, C, and D have characteristics that can be shared with other species as well, so none of those, and even B is a little edgy because the Lower primates' ancestry predates the earliest human ancestry.

identical DNA's are the best way to tell whether a specie is closely related to another.

Answer 3

Thank you both !
