Do the evolution
Transcript of Do the evolution
Early human fossils and archeological remains are the most important clues our past.
These include bones, tools and other evidence (footprints, evidence of hearths, or butchery marks on animal bones)
Fossilized bones, tell about the physical appearance of earlier humans. Bone size, shape, and markings left by muscles tell how those individuals moved around, held tools, and how the size of their brains changed over a long time
Bipedalism evolved over 4 million years ago.
Large and complex brain, the ability to make and use tools, and the capacity for language -- developed more recently.
Complex symbolic expression, art, and elaborate cultural diversity -- emerged mainly during the past 100,000 years.
Humans and the great apes of Africa share a common ancestor that lived between 8 and 6 million years ago.
Humans first evolved in Africa, and much of human evolution occurred on that continent.
The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa.
Early humans first migrated out of Africa into Asia probably between 2 million and 1.8 million years ago. They entered Europe between 1.5 million and 1 million years.
People first came to Australia probably within the past 60,000 years and to the Americas within the past 30,000 years or so. The beginnings of agriculture and the rise of the first civilizations occurred within the past 12,000 years.
Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
