I'll explain here again. The current theory suggests:

Modern humans and Chimps WERE THE SAME animal millions of years ago. This animal would have been an ape-like creature. Some geological catastrophe created a land rift, forcing some of the animals to live on barren land, while others lived on fertile land, complete with trees. The animals that lived on the barren land evolved into humans, while the animals on the land with trees evolved into chimps.

Humans had to evolve the ability to walk upright to survive on the tree-less landscape. It helped them see predators and hunt over the horizon.
