Why did early humans begin to walk on two feet?
Prehistoric humans had began walking bipedal since walking upright would require less energy than getting around on four feet. When I read a article on "Science Daily Web", anthropologists determined information about chimpanzees. They trained chimpanzees to use/run on treadmills; after a certain amount a time, they found that the ape ancestors would've walked upright because it requires less energy than four legs (2 legs, 2 arms). Besides requiring less energy, walking upright took less time than walking on 4 feet. The theories of humans walking on two feet can be vary but the closest answer that I can see is its an adaptation to their nature (ex. reaching an apple above them would be easier if we used hands and stood bipedal instead of crawling). Another major reason why prehistoric humans walked upright was attraction and hunting. When hunting, early hominids had to run in-ordered to chase the wild animals. Female hominds had to gather nutrition in baskets so it would've been easier for them to hold instead of putting the basket on their back. On the other hand, walking on two feet was an advantage and a development to our civilization. By walking upright, early hominids could had cross over exceedingly hot savanna. Million years ago, the height of grass was even taller than the hominids standing. When walking through the Savanna, early hominids had to communicate which bipedalism was an importanceSo this explains how humans walked on two feet but as I mentioned on the stop, answers of vary. In conclusion, this summarizes that walking upright was a tradition which prehistoric human adapted.
