I read a hypothesis that said since they didn’t have a way of recording things they had to have excellent memories.

If you are a hunter, gatherer you have to be able to remember successful hunting grounds of the past and how to return to them. Some could be quite far away.

Could be true. Who knows.

Good point. Humans became anatomically modern around 300,000 to 200,000 years ago, but intellectually modern around 70,000 to 50,000 years ago. Though this is disputed.There's a good summary on Wikipedia if you're interested.

There was a massive volcanic eruption around 74,000 years ago. It has been proposed that this caused a genetic bottleneck in the human population. Though this, too, has been disputed.

Homo Heidelbergensis, not homo sapiens. We evolved in Africa and migrated out to populate the world. To pick a random ancestor the human/chimpanzee last common ancestor (CHLCA) is theorized to possibly be graecopithecus, whose fossils were found in southern Europe. So at some point between CHLCA and homo sapiens our ancestors migrated into Africa and stayed there. The implication is that other human species could have left Africa sooner, or never came in the first place.

Honestly I don't think there's any reason to think they would be much different behaviorally, we know at least 3 species of human have mated in the past. They also existed well into the time period of modern humans so I would bet we mated with them too but it may not be easy to tell in the genomic record. They probably wouldn't mate unless they were similar in many ways, but mainly behaviorally. Classifications that distinguish between different species of human are mainly physical differences, this leads me to believe that ancient human species were much more alike than we would be led to believe by our current colloquial definitions of species.
