There is a long, ugly history of comparing black people to monkeys or other apes. Unfortunately for Terramagne, it comes out of the same background that causes a higher rate of simian primals among African-descended people: both black people and great apes come from Africa. Because all humans are primates, any population can produce simian or early hominid primals, but those usually draw on current or ancestral local wildlife -- for instance, snow monkey primals in Japan. But the rate is highest and the tension tightest among African and diaspora people with ancestors from those parts of Africa inhabited by great apes. As our closest living relatives, they are well represented among primals even though domestics are the majority. Racism just makes the connection more fraught, when primals of any kind already face serious challenges.

DNA contains large amounts that don't manifest. Regrettably the shorthand "junk DNA" has become common, which makes people think of it as useless trash, whereas the longer "Kitchen Junk Drawer" is immediately understandable as a collection of tools and supplies which are useful but not currently needed.
People fuck. The DNA of modern Homo sapiens includes a record of our ancestors interbreeding with several neighboring species -- quite possibly, all coextant relatives. The exact combination varies across different regional populations based on the available neighbors, such that Europeans and Africans tend to have different collateral DNA. Traits correlating with Neanderthal heritage have been traced fairly well, including red hair, which may support the claim that redheads are crayon soups.
Skin color is not a reliable marker of race. Actual racial differences appear in more obscure things like blood types, earwax, and twinning rates.
Obligate carnivores require meat. Some can't digest anything else, while others eat small amounts of other things.
