Lucy Bipedalism Evolution

With attention to Lucy, bipedalism is a unique quality that links us to the evolution of humans and who we are today. One of the earliest human trains discovered was bipedalism, which meant they possessed the ability to walk on two legs and it became a regular basis. This evolved over 4 million years. The oldest evidence of humans walking on two legs come from the remains of Sahelanthropus. Since it was bipedal, it helped this species survive in diverse habitats (“Walking Upright”). This was over 6 million years ago. As mentioned earlier, humans were mostly bipedal around 4 million years ago. Lucy, for example, showed characteristics of an individual that was bipedal. The shaft is angled relative to the knee joints. There is a prominent patellar

Throughout time, humans began to learn more and more when it came to using tools. Earlier humans in East Africa would use sharp stones they sharpened to cut, pound and get new food. The earliest tools were possibly made by the Australopithecus garhi about 2.5 million years ago. Beginning 1.7 million years ago, humans began to strike flakes off stone cores and shape it into hand axes. Fire was discovered, which provided cooking for earlier humans. With the ability to use fire for cooking and heating, it was successful in colder regions. Homo erectus was the first species in our line of evolution that had gone from tropical and subtropical to a temperate climatic zone. Fire was not used on a regular until Homo erectus began evolving into Homo heidelbergensis 780,000-400,000 years ago (Burton). Humans began to hunt large animals with wooden spears at least half a million years ago. However, almost 2.6 million years ago, they were already butchering large animals. It was more likely that they would grab the kills from lions and other predators to eat. This was a part of human technology for more than a million years and found throughout the world (“Introduction to Human Evolution”). More advanced traits emerged within the last 100,000 years such as art, diversity and symbolic expression. Humans began to use different materials for tools. They began making clothing, carving designs and fishing. Their advancements in hunting made humans able to get protein and survive despite it being
