Explain the features of Hominoids?
Answers
Answer:
Their general physique gives them a more upright posture than other primates. Their shoulder blades lie on their back, an arrangement that imparts a wide range of motion. Hominoids also lack a tail. Together these characteristics give hominoids better balance than their closest living relatives, the Old World monkeys.

member of the superfamily Hominoidea: extant members are the gibbons (lesser apes, family Hylobatidae) and the hominids. A hominid is a member of the family Hominidae, the great apes: orangutans, gorillas, chimpanzees and humans.
Answer:
A hominid is any human-like species, who is Bipedal (walks on two legs) and is intelligent (has a large brain and uses tools). The only living species of hominids is modern man or homo sapiens. Homo means man; sapiens means relating to man, or wise man, in Latin.
Explanation:
The two main characteristics of hominids are bipedalism and big brains. The brain case, or the skull, has increased in size over time to allow for the enlargement of the brain. It has also changed shape. The skull now has more forehead and a rounder shape. There is less separation between the brain and the face. The face has gotten flatter, the nose is less of a snout and humans have small teeth and jaws in comparison to the modern apes. Big brains allow for more learned behavior, such as using tools.
All hominids are able to walk upright. The human anatomy has had to adjust in a variety of different ways to accommodate walking up-right. The foramen magnum, which attaches the spinal cord to the brain, is at the bottom of the skull, rather than at the back. This allows hominids to see straight ahead.
The vertebrae of hominids vary in size from the top of the spine to the bottom. They are smaller at the top and larger at the bottom. The spine of hominids also curves, which helps to support the weight of the body, in an upright position.
The femur, which is the thigh bone in hominids, is angled towards the knee, which stabilizes the body in relation to gravity. Bipedalism can make it hard to balance and humans often fall, particularly when they're elderly. It can also cause back pain.
