What should be the Human population today if....?

Question

the humans existed 100,000 years ago?

two human beings; the second, 4; the third, 8; the fourth, 16; the tenth, 1024; the twentieth 1,048,576, the thirtieth, 1,073,741,824; and the thirty-first, 2,147,483,648. In other words, if we raise two to the thirtieth power, we have 1,073,741,824; or to the thirty-first power, 2,147,483,648 Therefore, it is evident even to the school boy, that, to have the present population of the globe, the net population must be doubled more than thirty times and less than thirty-one times. By logarithms, we find it to be 30.75 times. After all allowances are made for natural deaths, wars, catastrophes, and losses of all kinds, if the human race would double its numbers 30.75 times, we would have the present population of the globe....

Answer 1

Nice try, but Williams' arguments (which have been thoroughly debunked for a few generations now) use false assumptions and bad math:

Answer 2

Dude, you are assuming that no kids die. Humans were almost extinct as little as 75,000 years ago. Mitochondrial DNA studies have it down to only a couple small populations in Africa then. The early part of human existence was not happy. We weren't built for the cold of the ice age the way Neanderthal was.

The black plague wiped out almost half the population of Europe in the Middle Ages. There were similar plagues throughout history. There are also large starvation events all over the place. Entire populations were regularly wiped out. You just can't make the blanket assumption that the population is going to double every 30 years or so. It's silly.

Answer 3

You are right, because populations steadily increase exponentially only until a certain point, then they take off. Today's world population is completely in sync mathematically as having begun from the bottleneck of 8 people 4400 years ago. Populations slowly, gradually increased until about the 18th century, then they started growing exponentially, creating a growth curve. Anyone who has ever invested money in a good mutual fund sees the same phenomenon. Today's population is NOT in harmony with a belief that humans have been around for hundreds of thousands of years. It is mathematically impossible.

Answer 4

The numbers are garbage. If the population exceeds what the environments can sustain, it will stop growing. There was an ice age 10,000 years ago followed by the advances of agriculture. That's where the population growth came from.

Answer 5

I don't know but I do know there would be a least (if not more) over 40 million more people on the planet if people would stop murdering the unborn.

Answer 6

Some families have lots of kids. Some families have few kids. Some have no kids.
