When did the human life start?

Answer 1

There is, as yet, no definitive answer to this question.

Answer:

A lot of the answer depends on your definition of "Human". There were many hominid precursors to the human race so a timeline from Australopithecus and winding up with us would be:

• Australopithecus ramidus - 5 to 4 million years BCE
• Australopithecus afarensis - 4 to 2.7 million years BCE
• Australopithecus africanus - 3.0 to 2.0 million years BCE
• Australopithecus robustus - 2.2 to 1.0 million years BCE
• Homo habilis - 2.2 to 1.6 million years BCE
• Homo erectus - 2 to 0.4 million years BCE
• Homo sapiens - 400,000 to 200,000 years BCE
• Homo sapiens neandertalensis - 200,000 to 30,000 years BCE
• Homo sapiens sapiens - 130,000 years BCE to present

No effort was made to include the various archaic homo sapiens types, and homo neandertalis was inserted even though they were not linear ancestors of ours except for some cross breeding.

Answer 2

No one really knows the answer. There is an endless debate going on about this. Some people say it's once the child is conceived. Others say it's when the child takes it first breath...... Think about this; our brain controls what we do, think, and say. With out it we are dead. So shouldn't life start when the brain is developed?

Answer 3

God created man on the sixth day of creation in the garden of Eden.

Another view:

A frequently-heard answer is that our ape-like ancestors moved, or were driven, from the jungle to the grasslands, losing our ape-hair in response to the heat. However, baboons, who also did this, have not lost their hair, nor have any of the other grassland animals. A recent hypothesis suggests we had an aquatic period (other animals who have streamlined, minimised, or total loss of, body hair had or have an aquatic period - otters, seals, hippos, etc). The suggestion is that our ancestors evolved the primary human characteristics (vertical posture, etc.) as a response to living in, or habitually frequenting, water - and the target place for this origin is the Danakil Horst, at the mouth of the Red Sea. It had periods of isolation as an island (which would have encouraged ape-like ancestors to seek food in the water) between times when a land bridge would have enabled the successive waves of hominids to 'appear' in the Rift Valley and further south.

Answer 4

Scientific evidence suggests that human life began around 300,000 years ago with the emergence of Homo sapiens in Africa. This species eventually spread across the globe, evolving and adapting to various environments over time.

Answer 5
