Question

which group includes only bipedal animals
primates
lesser apes
hominids
hominins

Answer 1

The group that specifically includes only bipedal animals is **hominins**. Hominins are a subgroup of hominids that specifically refer to modern humans and our direct ancestors who are characterized by bipedalism. While primates, lesser apes, and hominids include both bipedal and non-bipedal species, hominins are exclusively related to bipedalism.
