Early Humans

Most scientists are currently recognizing about 15 to 20 different early human beings. However, scientists do not all agree on how these species are related or which species are disappearing. Many of the earliest human species, and of course most people left no living offspring. Scientists also discussed the earliest human specific species and ways to identify and classify factors that affect the evolution and extinction of each species. Early humans first migrated from Africa to Asia, perhaps 2 to 8 million years ago. They later entered Europe, between 5 million and 1 million. Long ago, modern human species lived in many parts of the world. For example, some people came to Australia for the first time in the past 60 thousand years, others may have come to the US in the past 30 thousand years. The origin of agriculture and the emergence of the first civilization occurred within the past 12,000 years.

The earliest human beings were found in Africa, and this is where human evolution takes place. These fossils of early primitive mankind lived from 2 million to 6 million years ago, and all came from the continent. Most scientists believe that early humans migrated from Africa to Asia 2 million to 1.7 million years ago and entered Europe in the last million years. The following are some of the highlights of the earliest human species that scientists have identified so far. African ticks may have evolved about 6 million years ago and have two skeletal features that distinguish them from ticks: four small dogs compared to the long dogs found in almost all other primates The main exercise mode is walking with teeth on both sides of the front teeth, and most importantly with both feet or walking with both feet.
