Here is your answer
Explanation:
Wheel is the discovery that changed human life bcz after the discovery of wheel everyone can go anywhere quickly. It made human life easier.
In recent years, anthropologists around the world have discovered new human ancestors, figured out what happened to the Neanderthals, and pushed back the age of the earliest member of our species.
Taken together, these breakthroughs suggest that many of our previous ideas about the human origin story - who we are and where we came from - were wrong..
Until the last few years, most scientists thought that the first members of our species, Homo sapiens, evolved in East Africa approximately 200,000 years ago. Then humanity remained in Africa for the next 140,000 years, according to this line of thought, before venturing into Europe and Asia in what's known as the "Out of Africa" migration about 60,000 years ago. Those early humans proceeded to take over territories once occupied by other human ancestor species like Neanderthals.
But this understanding of history has been upended as new discoveries revealed that the first humans emerged much earlier than we thought and in a different part of Africa. Rather than simply replacing other competitor species, Homo sapiens seem to have interbred with them.
As researchers make more of these breakthroughs, the human evolutionary puzzle gets more complicated.

A 2017 finding in Morocco threw into question the idea that modern humans originated in East Africa. Those bones were significantly older than any others ever found.
A 2017 finding in Morocco threw into question the idea that modern humans originated in East Africa. Those bones were significantly older than any others ever found.
Researchers determined that the bones unearthed in Morocco's Jebel Irhoud region are 315,000 years old — roughly 100,000 older than the bones previously considered oldest modern human fossils. (Those fossils, found in Ethiopia, were roughly 196,000 years old.)
The remains were also found in a different area of Africa than most other ancient human bones: North Africa instead of East Africa. That suggests our earliest ancestors may not have lived in just one part of the continent.
"There is no Garden of Eden in Africa, or if there is, it is all of Africa," anthropologist Jean-Jacques Hublin, who led the Morocco expedition, said at the time.
