What is advantage of walking upright as opposed to walking on all fours?
Becuase that way you wont have the sun beating on your back OR The real, biological reasons that animals evolved to be bipedal from being quadrupedal are many and varied. But if you think about what life would be like for an early human if he had to walk on his hands, you will get the picture soon enough. a) he can see farther across thh African horizon when standing up. (picture a meerkat) b) She can carry her young in her arms. c) they can use their hands for other purposes while continuing to move forward. whether that is picking apples, carrying a captured kill back to the home, whatever it is. The benefits that developed after the fact of evolution are just as varied. But it would be a mistake to say that they "chose" to walk upright, but instead, the ability to walk upright helped certain strains of the early humans to survive. whether it was the parents that could carried their young from danger and those that couldn't didn't, or if it is because the ability to carry your young means you can bring them everywhere, and means that you don't depend on a den for your species to survive (you can operate as a nomad or scavenger and still produce and rear offspring), or if simply you can see the lion coming better than the next guy, it is a process of mutation and selection by nature of the most able to survive, not a conscious choice on behalf of the evolving creature. Answer: There are plenty of advantages: 1) as tropical forests were beginning to become smaller, walking helps Homo sapiens moved across the grasslands easier to get sources of food. 2) Standing upright helps ancient people defended, protected themselves from animals. When chimpanzees or gorillas become excited, they stand in an upright posture and shake a stick or throw an object. 3) By standing upright: appear bigger and more impressive in size than they normally are. In addition, the ability to stand up and get a wider view of the surroundings gives them an advantage in the tall grasses. 4)Walking upright also frees up the hands to carry objects, such as tools.
