Hominins are a group of extinct and living creatures that belong to the family Hominidae and are known for their upright posture, bipedal locomotion, and larger brain size compared to other primates. Some of the important characteristics of hominins are:
1. Cranial features: Hominins have a larger brain size, flat face with front-facing eyes, reduced canine teeth, and smaller chewing muscles.
2. Dental features: Hominins have a parabolic dental arch, rounded molars with thick enamel, and reduced canine teeth, which suggest a shift in diet.
3. Pelvic features: Hominins have a shorter and broader pelvis with a more circular inlet as compared to other primates, which supports bipedalism and the accommodation of a larger brain.
4. Limb bones: Hominins have long and straight thigh bones, angled knee joints, and a stable foot arch that allows for efficient walking and running.
5. Bipedalism: Hominins are known for their bipedal locomotion, which is the ability to walk on two feet upright. This characteristic allowed them to explore different environments and increase their chances of survival.
Overall, hominins have a unique combination of anatomical, physiological, and behavioral characteristics, which distinguish them from other primates and allow them to adapt to their ever-changing environment.
