Question

A fossil skeleton with a basin-shaped pelvis, a central foramen magnum, and arched feet would most likely be classified as a(n) __________.

Answer 1

These characteristics are observed in biped organisms

Step-by-step explanation:

A biped organism is able to use two legs for walking. Bipedalism is an evolutionary adaptation produced by several skeletal changes shared in all bipedal species. The central foramen magnum, a short wide pelvis, and arched feet are factors that influence bipedalism, these features are required to achieve a better balance during the bipedal movement

Answer 2

The answer is 'biped', i.e., an upright walking animal. The basin-shaped pelvis would support abdominal organs as well as mechanically assist locomotor and postural muscles. The whole at the bottom of a bipedal animal's skull through which the vertebral column attaches to the skull is called the foramen magnum. The arched feet of a biped are to support increased weight.
