Final answer:
Yes, Darwin presented evidence that supports the idea that chimpanzees' and humans' DNA differs by less than 2%. The similarity in DNA sequences between humans and chimpanzees is the strongest evidence for evolution from a common ancestor.
Step-by-step explanation:
Yes, Charles Darwin presented evidence that supported the idea that chimpanzees' and humans' DNA differs by less than 2%. When scientists determined the entire genetic code of both humans and chimpanzees, they found that we have over 98% identical DNA. This similarity in DNA sequences is the strongest evidence for evolution from a common ancestor.
For example, scientists can compare their DNA sequences and the more similar the sequences are, the more closely related the species are presumed to be. Humans and chimpanzees share about 98% of their genes, which means they shared a common ancestor in the not-too-distant past.
Furthermore, the similarities between embryos of humans and chimpanzees suggest that we have a common ancestor. Although humans did not evolve from chimpanzees, the similarities in the embryos of both species indicate a shared ancestor. As the common ancestor evolved, humans and chimpanzees developed different traits, leading to anatomical differences.
