Why do humans walk upright.pdf

Survival depends on the environment. A creature survives in a new

environment, and its ability to survive is the decisive factor. Human survival

ability comes from knowledge, and knowledge comes from innovation, which is

the fundamental reason leading human evolution. Human upright walking is a

sign of the evolution of ancient apes to humans. However, walking upright is only

a result, and the reason is that ancient apes need to use their hands to solve the

problem of survivability in the new environment. The evolution of human beings

is fundamentally different from that of other creatures, which indicates that the

evolution of human beings has inherent and essential particularity. This

particularity lies in the occasional emergence of innovative people in human

groups. Their innovation has not only improved human survival, but also led to

human evolution.
