Btw human history more or less: 4milions years ago = 4*10^6
Modern man: 200.000 years ago 2*10^5
So there is a 10 factor....and probably the average population between (200k years ago and now) / (4M and 200k years ago) is less than a 10 factor....this could be a rough estimate...
About just 2 centuries we are over the 1Billion population....so the average during the whole history is pretty low the same....I would say something around 10^4 people.
So it's possible.
Btw I think is not possible to calculate accuratly this thing....noone knows how many humans being lived on the earth for sure...so it would be always a rough estimate.
P.S.
It's very clear watching at your graph....look how the population peak is just about some last centuries (the most last century, so 100 years vs 4M of years)....so if you watch at the whole history of humans, you could almost delete that peak...cause the period of time is way much more relevant.....
Do you even know what history means? History specifically means things that happened after writing. Stuff that happened before is defined as pre-historic era/stuff.
ALSO
Human prehistory totally did not begin 4 million years ago. You could barely tell that whole HUMAN SPECIES was formed around 2.5 MILLION years ago. Which is 1.5 million years off from your estimation or almost 50% which is quite a lot on any scale. And I dont think that you could even define them as humans in some practical ways. Sure they might have used some stones as tools. But so do other animals. Neanderthals are already close to us, they had some basic language and they made and used basic tools, hunted in groups, buried their dead. Things that you could define human-like.
Some very very early human pre history could be said has formed like 10 000 years or so ago.
Also why the heck dont you just write numbers properly? Marking such small number as 10 000 or even 1 000 000 000 in a discussion like this with scientific notations is just utterly stupid.
ALSO
Even with your method of calculation
Lets say there were average of 20 000 humans living at any given time during the last 4 million years.
As units, lets use living human/year.
So we multiply average amount of humans by year. And we can get some nice numbers.
Acorn eating people: 20 000*4 000 000 = 80000000000 years-that-humans-have-lived-units
Last 100 years I'd say average population has been roughly 4 or 5 billion.
Rice eating men: 100*4 000 000 000 = 400000000000 years-that-humans-have-lived-units
400000000000 divided by 80000000000 = 5
So we can say that years-lived-by-human has been 5 times as much in the last 100 years than your whole "acon eating era"
So we can come in conclusion that you are absolutely wrong on everything! Feel free to ask me why if you did not understand!
edit: you areblatantly wrong be shamed of yourself!
