Answer 1

The scientist concludes that it could be a primate or a hominid, but not a hominin because hominins are characterized by bipedalism or walking upright on two legs. The fossil of an animal that walks on all fours could be a primate or a hominid since these groups include species that walk on four legs. However, further analysis and comparison with other fossils and species would be needed to determine the exact classification of the animal in question.
