Why did early humans begin to walk on two feet?

Do you ever wonder what we use our hands for? Why did we decide to walk upright? Humans today are adapted to walk straight and upright, or bipedal. This question also goes for early humans. Generally, prehistoric people walked on two feet, but most of them walked quadrupedal, or on all fours, like all the non-human apes.
Early humans had to use a lot of objects in order to maintain a healthy living. For example, they used bow – and – arrow to strike the animal for instance a hippopotamus as a food source, they used their hands to make tools like sharp hand axes or jewelry, and to communicate with each other using hands- with this really weird language which is easier than ours and including snapping clapping sounds etc… They obviously cannot eat with their legs, head or back, but they could eat with using their hands, just like every other person today.
Today most of the people don’t make objects, yet they can buy the objects in the supermarkets resulting in easier work. In conclusion, early people began to walk on two feet because they needed to make tools, to communicate and to make life easier to them.
