Putting it simply: It is IMPOSSIBLE to construct a taxonomic category which includes chimps, orangs, and gorillas which does NOT include humans.

Here are a few:

same blood types: https://pubmed.ncbi.nlm.nih.gov/6775134/

prehensile hands: [obvious]

eyes: Just look at a chimp eye close up in the zoo and you will see ZERO difference in structure.

DNA: humans have a 98% match with chimps, higher than DNA match with gorillas or orangutans; that ALONE proves that humans are apes if you are rational.
