Very true. And if people online thought about it,
instead of simply being dogmatic, they might
explain to you that it isn't really about time at
all.
It's about food. The more food you have the higher
the population density you can support.
See, hunter-gathering isn't very efficient. You
can't support a great many people. You need a
lot of land to feed people, if you're a hunter
gatherer society...
"Aquatic Ape" changes the equation some. The sea
will support a higher population density than the
land, for hunter-gatherers.
Think about it. A fisherman is literally a "Hunter
Gatherer," even a modern fisherman...
Still, don't project modern man backwards in time!
Without technology, even the sea couldn't feed a
very large population. You'd just be picking shellfish
up, and any beached fish. Learn to use sticks as
probes and you can easily find/dig up hidden shellfish,
drastically increasing your meals. Figure out how to
use that stick as a spear and you can start spear
fishing for even more meals... figure out how to drive
fish towards shore and, wow, now you're feeding
everyone in one go!
Problem with availability. You'd just be consuming all
the available resources in a given stretch of beach
then moving on. I mean, if this model was true, if it
really happened that way then man would have migrated
out of Africa, "Coastal Dispersal" only to wind up in
the middle east, India & beyond...
Oops.
Okay, so you see the problem here?
Population size is restricted by the availability
of food, and the more primitive the people the
fewer sources, the less efficiency... the less food.
How do you open clams without "Tools"?
And "Fishing" requires way more advancement than
picking up shellfish...
So man's population didn't really grow so much
because a lot of time had passed, the population
grew because the more advanced man because, the
more knowledge he gained, the more advanced his
technology became THE MORE FOOD THERE WAS. And,
ultimately, food dictates population density.
