SUMMARY

Homo sapiens have existed for approximately 200,000 years, a figure that includes the subspecies Homo sapiens idaltu. Archaeological evidence suggests that the first civilizations emerged around 10,000 years ago, coinciding with the Neolithic Revolution, which marked the transition to permanent settlements. Genetic evidence currently plays a significant role in understanding human evolution and the timeline of early human existence. The development of language is theorized to have been influenced by the need for hand gestures in communication.

PREREQUISITES
  • Understanding of human evolutionary biology
  • Familiarity with archaeological methods and findings
  • Knowledge of the Neolithic Revolution and its significance
  • Basic concepts of genetics and its application in anthropology
NEXT STEPS
  • Research the role of genetic evidence in human evolution studies
  • Explore archaeological findings related to early Homo sapiens
  • Investigate the impact of the Neolithic Revolution on human societies
  • Study theories on the origins and development of language in hominids
USEFUL FOR

Anthropologists, archaeologists, historians, and anyone interested in the evolution of human societies and the origins of language.

How long has people as Homo-Sapiens existed? I would imagine that there is no way to pinpoint an exact time due to the subject's pre-historical nature. What do Archaeologists say about when the first Homo-Sapien was born? When was the very first civilization established, and where?

Genetic rather than archeological evidence seems to dominate now. The figure is usualy given at c. 200 000 years for Homo Sapiens and that includes Homo Sapiens Idaltu.
As for 'civilisation', the neolithic revolution is usualy given at about 10 000 years ago or just a bit later, that is the beginning of permenant settlements so far as I know.
 
If you are asking when did language develop then my theory is that hominids stood upright in order to use their hands for sign language.
