Migration In Africa

The human race begins roughly around 2.4 million years ago, and is disbursed throughout Africa, Asia, and Europe. It is from the Homo ergaster, who remained in Africa, however, that evolved into Homo sapiens. Moreover, natural selection is the outcome of species who survived by adapting to global climate changes during migration process, thereby producing offspring and strengthening their kind in the evolutionary process. It was fifteen thousand years ago, an immense migration of people made its way across the Bering Strait, and not until 10,000 B.C. that the first humans reached the arid North American continent otherwise known as Aridoamerica.

According to Olmec legend a human woman and a jaguar bred to create a hybrid who was the ancestor of all Olmecs.
Moreover, the Olmec possessed extensive knowledge in the Long Count system as mentioned earlier. However, the most astonishing mathematical discovery was the concept of the number zero, much more advanced than in European countries at the time. The Olmec were also capable to predict eclipse with accuracy, through observations and recording of the planets orbit. A two-calendar system is also said to be the creation of the Olmec, meaning a 365-day solar calendar and a 260-day sacred calendar, a date system which influenced later cultures in
