In summary, the estimated time for Homo-Sapiens to have existed is around 200,000 years according to genetic evidence, including Homo Sapiens Idaltu. The first civilization is believed to have been established around 10,000 years ago during the neolithic revolution, which marks the beginning of permanent settlements. Some believe that language may have developed as hominids began to stand upright and use their hands for sign 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.
 

How Long Have Homo Sapiens Walked the Earth?

Homo sapiens, the species to which all modern human beings belong, have a history spanning thousands of years. Let's explore some common questions about the timeline of Homo sapiens on Earth:

Q1: When Did Homo Sapiens First Appear on Earth?

Homo sapiens, as a distinct species, are believed to have appeared approximately 200,000 years ago. This estimate is based on fossil evidence and genetic studies that trace our common ancestry to a single population of early Homo sapiens.

Q2: Where Did the First Homo Sapiens Exist?

The earliest evidence of Homo sapiens comes from Africa, particularly East Africa. Fossils and archaeological sites in regions like Ethiopia and Kenya provide insight into the emergence and early migration of our species.

Q3: How Did Homo Sapiens Spread Across the Globe?

Homo sapiens gradually migrated out of Africa and dispersed across the world. This process, known as "Out of Africa," began around 70,000 to 60,000 years ago. Early human populations ventured into Asia, Europe, Australia, and the Americas over thousands of years, adapting to diverse environments.

Q4: What Were the Key Milestones in Human Evolution?

Human evolution is marked by significant milestones, including the development of complex tools, the mastery of fire, and the emergence of agriculture. These advancements contributed to our species' ability to thrive and shape the world.

Q5: How Can Scientists Determine the Age of Early Homo Sapiens?

Scientists use various methods to determine the age of early Homo sapiens and their artifacts. Radiocarbon dating, luminescence dating, and genetic analysis of ancient DNA are some of the techniques employed to estimate the age of fossils and archaeological findings.

Q6: What Distinguishes Homo Sapiens from Other Hominins?

Homo sapiens are characterized by their advanced cognitive abilities, complex language, capacity for abstract thinking, and cultural diversity. These traits set them apart from other hominin species that lived in the past.

Q7: How Has Homo Sapiens' Lifestyle Evolved Over Time?

Homo sapiens have undergone significant changes in lifestyle, transitioning from nomadic hunter-gatherer societies to settled agricultural communities and, eventually, to modern urban societies. These shifts have shaped our cultures, technologies, and societies.

Q8: What Is the Significance of Homo Sapiens' Long History?

The long history of Homo sapiens on Earth is significant as it reflects the development of human societies, technology, and culture. It also underscores our capacity for adaptation and innovation, which has allowed us to thrive in diverse environments.

Q9: What Is the Current Population of Homo Sapiens?

As of the most recent estimates, the global human population exceeds 7 billion individuals. This remarkable growth is a testament to our species' ability to populate and adapt to various regions of the planet.

In summary, Homo sapiens have walked the Earth for approximately 200,000 years, with our origins in Africa. Over time, we have spread across the globe, evolving culturally, technologically, and socially. Our long history is a testament to our capacity for adaptation and innovation.
