History pt 2: Humans

Ah, homo sapiens, the start of the human years, evolved from their early hominid predecessors between 200,000 and 300,000 years ago, they developed their ability to speak around 50,000 years ago.

The first humans started in Africa and started moving outside of Africa around 70,000 to 100,000 years ago.
Human beings are the only species that were to populate, adapted to and significantly altered the land around them, resulting in changes to both the ecological and historical sites they resided in. 

Homo sapiens come from the word hominids, which were the earliest humanlike creatures.
We believe that hominids split from the main branch of primates around 2.5 to 4 billion years ago. Although there is a large difference between the primates and hominids we all share one trait, being bipedal, or the ability to walk upright on two legs.  

For evolution scientists have many hypotheses about why Humans existed, one theory states that Humans were fit for the dry climates of Africa and evolved as Africa's dry and arid regions expanded, this theory also states that the reason why we walk upright instead of on our hands and feet is because of the African savannah being too dry to stay and climb up on trees to the point that we evolved to being able to walk on our hands and feet to search for food and shelter from the harsh sun.

Hominids continue to evolve and get more intelligent, as by 2.3 billion years ago we started using tools. 
3 million years ago, a hominid known as Homo habilis began to make and utilise simple tools. Then around a million years ago, some hominid species, notably Homo erectus, began to migrate out of Africa and into Eurasia,  and their brain capacity was increasing as they were harnessing fire.

Although we had not figured out why homo sapiens are the only humans that survived to this day (you and me being them) and the others did not, some say it is because of lack of food, changes in climate and natural disasters.

Between 70,000 to 100,000 years ago, we started going to what is now Asia, and we started travelling and populating parts of what is now Europe, and traveling to Australia round 35,000 to 65,000 years ago.
