AI Thread Summary
Homo sapiens are estimated to have existed for around 200,000 years, with some references including Homo sapiens idaltu in this timeframe. Archaeological evidence supports this timeline, although genetic evidence is increasingly influential in understanding human origins. The establishment of the first civilizations is typically linked to the Neolithic Revolution, which occurred approximately 10,000 years ago, marking the beginning of permanent settlements. The discussion also touches on the development of language, suggesting that early hominids may have used upright posture to facilitate hand gestures 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.

(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam.

Thread '(Unprecedented?) Cluster of earthquakes in Greek islands'

These last days, there is a seemingly endless cluster of rather powerful earthquakes close to the islands of Santorini, Amorgos, Anafi, and Ios. Remember, this is a highly volcanically active region, Santorini especially being famous for the supervolcanic eruption which is conjectured to have led to the decline of the Minoan civilization: https://en.m.wikipedia.org/wiki/Minoan_eruption To grasp the scale of what is happening, between the 26th of January and the 9th of February, 12000...
