The term reptile is problematic, since its conventional usage unnaturally excludes birds and mammals, and the modern consensus is that the reptiles are not a natural group. [164] After the first fully terrestrial tetrapods evolved, one of their lineages split into the synapsids (the line leading to mammals) and the diapsids (the line leading to ...

Female chimps learn to fish for termites earlier and better than the young males. [40] Females also spend more time fishing while at the mounds with their mothers—males spend more time playing. When they are adults, females need more termite protein because with young to care for, they cannot hunt the way males can.
During flight, the bones undergo bending and shearing stress; the bending stresses felt are smaller than in terrestrial mammals, but the shearing stress is larger. The wing bones of bats have a slightly lower breaking stress point than those of birds. [56] As in other mammals, and unlike in birds, the radius is the main component of the forearm ...
