Humans, or by their scientific name homo sapiens, belong to a group called hominids. Creatures in part of the hominids group, are the earliest known human like creatures. A trait that is commonly shared among hominids is the ability to walk on two legs or bipedalism. According to Khanacademy.org, it’s believed that hominids started to separate from other primates between 2.5 and 4 million years ago, around eastern and southern Africa.
There are many theories to why the early hominids begun to evolve. One theory was that with the expansion of the savannah, it slowly forced their homes in the forest to shrink. Because of this, it may be one of the reasons we started to rely on walking upright, on the ground, rather than continuing to climb trees.
As hominids continued to evolve, they gained more unique traits and characteristics. One of these characteristics was that their brain capacity was increasing, and then a species of hominid, homo habilis, began using tools around 2.3 million years ago.
Then, around 1 million years ago, some species of hominids, such as homo erectus, began leaving Africa and moving towards Europe and Asia. And when they arrived, they began making important advances like being able to use fire.
The first modern humans happened around 200,000 and 300,000 years ago. And the ability to use language happened around 50,000 year ago.
Later, between 70,000 and 100,000 years ago, modern humans began leaving Africa to ocupate Europe and Asia. The first humans reached Australia by around 35,000 and 65,000 years ago.
According to scientists, during the Pleistocene Ice Age, a land bridge was created, connecting Asia and North America around 13,000 years ago. It is believed that people came to America from Asia by this land bridge.
