Incorrect. 200,000 years ago, humanity was one of several human species. We were barbarians living in caves. and we were NOT, I repeat, NOT
psychologically the same.
Again, we call this Behavioral Modernity. It is a fact that our bodies are older than our minds. Behavioral Modernity is the time when we started
using that intelligence like we do now. When the biochemistry of the mind, and the mind itself, evolved to open the keys to imagination and art and
science. It is when the cave paintings began and when we started developing.
This was 50,000 years ago.
Humanity is 50,000 years old as we are now. 200,000 years ago we were busy killing Homo sapiens idaltu and Homo Erectus and various other groups. No
society. We were still animals.
200,000 years ago anatomically modern humans existed. This means that the VAST majority of our genetic code was the same as it is now, even mentally.
Humans were not barbarians living in caves, they likely lived in bands and/or tribes in a variety of environments. I'm also suspicious of your use of
the word "barbarians" to assert that they were somehow stupid, brutish, and violent. The reality is that to this day WE STILL KILL EACH OTHER in
farrrr more barbaric manners than during prehistory. And the level of violence in prehistoric society is still not fully understood and even can be
downplayed in its incidence the more we learn. Many modern tribes aren't very violent at all, most tribal warfare causes few casualties and serves
mostly as a ritual/symbolic release of inter-tribal pressure.
As I point out below, the Toba cataclysm seems to be responsible for "behavioral modernity" however there is still scientific debate about the term
and its implications in separating humans before and after that point. I'm not sure that it was a divisive enough event to label humans before that
time as stupid or incapable of language/culture. Primitive language, tool use, clothing, and cooking of food developed even BEFORE modern humans. Due
to severe climate changes, environmental forcing may have had a significant amount to do with the development of more advanced culture 50kya as
Humans practiced society before 50kya, they had collective forms of socialization, family, and culture. Perhaps they were more technologically
primitive, but this does not mean they were merely "animals". The TRUE explosion of technology occurred 10,000 years ago during the agricultural
revolution and this certainly doesn't mean that humans are mentally more capable now, as it was a drastic CULTURAL shift. The fact also remains that
humans are not somehow magically NOT animals, we are still animals (barring a future trans-humanist 'artificialization' of humans), except we have
the largest neocortex and an inflated sense of self-worth and domination over other species. A larger neocortex does not mean we are necessarily more
civil than other species, especially considering the fact that we are causing the planet's sixth great extinction event.

Modern man were the surviving members of a population bottleneck from an estimate of 90 to 70.000 years ago from a natural cataclysm that could have
wiped us of the planet as it caused the population to drop to only an estimate of 2000 members. The eruption of lake Toba, a super volcano has been
pointed at as probable cause of this event.
The Toba cataclysm and subsequent human population bottleneck seems to be the best explanation for the development of "behaviorally modern" humans
50,000 years ago.
