Hominids evolved and developed for millions of years prior to the arrival of Homo sapiens on the Earth. This evolution was slow. The development of a new skill or tool often took thousands of years. With the arrival of Homo sapiens, this all changed. The speed of advancements increased dramatically. Instead of thousands of years, great progress was made in hundreds or even dozens of years.
The first Homo sapiens are believed to have been the Neanderthals. Neanderthal people first appeared on the Earth around 200,000 years ago in Africa. They migrated from Africa to the rest of the world around 100,000 years ago. Neanderthals were around five to six feet in height. They had thick sturdy bones, and muscular shoulders, legs, arms and necks. Neanderthals also had large brains. In fact, their brains were slightly larger than those of modern humans.
