I studied anthropology at university. I have an MA in the field. I can assure you that I am not a ‘Creationist‘ and that chimps are NOT our ancestors. In a story published by the BBC on April 27, 2015, titled “Lower back pain linked to chimpanzee spine shape” a caption appeared under a photo of a chimpanzee that read “People with lower back problems are more likely to have a spine similar in shape to the chimpanzee, our closest ape ancestor.” I notified the editor and the caption was replaced with “Chimpanzees are our closest primate relatives” almost immediately. Impressive and now accurate except they moved the original text that still referred to chimps as our ancestors to the start of the story.
Chimpanzees genus (Pan) and humans genus (Homo) share approximately 98.8% of their DNA. 1 However humans did not evolve from chimpanzees or vice versa. Humans and chimpanzees diverged from a common ancestor about 8 million years ago. 2 We are related, but chimps are no more our ancestors than your brother is your grandfather (unless you come from a very strange family but we don’t need to know about that thank you).
