Answer 1

The term bipedalism means the ability to walk upright on two feet. Neanderthals adapted to Europe's colder climate with a wider shape, and modern humans are classified as Homo sapiens. The skull found by Dart was called Australopithecus africanus.

Step-by-step explanation:

Bipedalism refers to the ability to walk upright on two feet, which is a significant feature of human evolution. Hominid bipedalism required complex anatomical changes such as the angling of the femur, the evolution of spinal curves, and the realignment of toes for efficient walking. The Neanderthals evolved a wider, stockier body shape to adapt to the colder climate of Europe. The current species of humans is known as Homo sapiens, and the hominid skull found by Raymond Dart was classified as Australopithecus africanus, which is one of the early evidence of bipedal hominins. Analysis of morphology, including limb length and the position of body parts, helps scientists hypothesize how creatures, including extinct dinosaurs, moved and how certain anatomical features were advantageous for their locomotion and survival.
