Humans: Where We All Began Humans have roamed this earth for thousands of years. Considering that, we can't help but raise the question of where we all came from. Around the 1950s, it was widely believed among European scientists that Homo sapiens originated in Europe or Asia around 60,000 years ago. Based on more recent discoveries by Mary Leakey and her husband Louis while excavating in East Africa, we now believe that Homo sapiens may have first emerged in Africa many years earlier. Of course it is impossible to know exactly when the human species first emerged, but based on fossil evidence, most paleoarchaeologists believe that around 6 million years ago, the human ancestral line split from that of the chimpanzee and evolved into a new group.

She was only around 3½ feet tall and had very long arms. Based on her body’s shape, she was believed to be able to walk upright on two legs and also climb trees with great ease, scientists believe that her species used resources from various environments, such as woodlands and grasslands. Judging from the evidence of large muscles on her arms and upper torso, she must have had very powerful upper arms and a strong chest. She had feet that were capable of supporting her entire weight, but her toes resembled that of a tree-climbing ape, being long and curved. Despite her physical resemblance to ape species, her body was very capable of supporting her weight while walking upright. She had thigh bones that were angled inwards and a short, broad pelvis that helped keep her body upright. These are both required in order to walk efficiently on two legs. Lucy was a very early stage of hominid species that have since taken on different shapes and become more and more capable of thriving on this planet. From studying fossilized bones such as that of Lucy’s, we can pursue further studies on how greatly humans have evolved over the years. (Human
