Final answer:
DNA sequences provide evidence of common ancestry and genetic similarities between humans, chimpanzees, and gorillas. The mtDNA tree shows the maternal lineage and the common ancestor of modern humans.
Step-by-step explanation:
The genetic sequences in DNA can help answer the human/chimp/gorilla question by providing evidence of common ancestry and genetic similarities.
By comparing DNA sequences, scientists can identify similarities and differences between humans, chimpanzees, and gorillas, which can give insights into their evolutionary relationships.
The mitochondrial DNA (mtDNA) tree, also known as the mitochondrial Eve, shows the maternal lineage and can be used to trace the common ancestor of modern humans.
