The Neanderthals were a group of ancient humans who lived in the Earth's Paleolithic age.
Compared to the modern homo sapiens who ruled the earth, they had a stronger physique, a stronger upper and lower jaw, and even a larger brain capacity.
At the same time, the Neanderthals had also mastered the skills of building camps and grinding tools.
Supposedly, they had been invincible in the Paleolithic age.
However, after tens of thousands to hundreds of thousands of years on earth, they mysteriously disappeared.
Only 1% to 4% of their genes were left in modern Earthlings as evidence that they had been here before.
Archaeologists and anthropologists speculated that although the Neanderthals were stronger and smarter than modern Homo sapiens, they had two fatal flaws.
For some reason, their language ability and imagination were naturally not as developed as modern Homo sapiens.
