What humans lived 500000 years ago?

Researchers have announced the naming of a newly discovered species of human ancestor, Homo bodoensis. The species lived in Africa about 500,000 years ago, during the Middle Pleistocene age, and was the direct ancestor of modern humans, according to scientists.

What was the population 1 million years ago?

Full Transcript. At one time or another, you’ve probably said, “It’s a small world.” Well, it used to be much, much smaller. Because according to scientists from the University of Utah, about a million years ago our ancestors numbered fewer than 20,000.

When was the lowest human population?

Around 70,000 years ago, humanity’s global population dropped down to only a few thousand individuals, and it had major effects on our species. One theory claims that a massive supervolcano in Indonesia erupted, blackening the sky with ash, plunging earth into an ice age, and killing off all but the hardiest humans.
