If evolution really happened, why does the human population curve go back to just 4,400 years?

Question

This curve takes into account war, disease, natural disasters, etc. If you have taken statistics, you should be familiar with the bell curve. Heck, if you are or were ever a student you should be familiar with curves.

Answer 1

The human population extends back at least one hundred thousand years. The population curve is predominately logarathmic.

Answer 2

1) Bell curve (normal distribution) is asymtotic and never reaches the zero value, so it just cannot curve back "to just 4400 years". With a top of the curve at say 6 billion, I wonder how you can know when the curve goes less than one with such detail. So the statement is obviously false.

2) Anyway Bell curve absolutely doesn't apply at all here. It's a symetrical distribution curve, not a grows curve. For those who don't know statistics, its shape is a bell. It describes for example, in a given population, how many people have average IQ (the central and highest part), how many have less-than-average and more-than-average IQ (the descending slopes on both sides), and how many are completely stupid or genious (lowest parts, farther on both sides). So the statement is totally irrelevant. The additional details ("This curve takes into account war..") are only here to fool the idiots. I guess that you are in the lowest part of the curve, and let people guess on which side...

Answer 3

this is why evolution needs to be taught in school :P

how can someone just arbitrarily make a curve and oops look at that it goes to "exactly" 4400 years ago, just like the ID people insist.

does said curve take into account things like climate change? does it take into account the fact that the earth doesn't consist of just a big circular continent where spreading across the land requires consistant effort? remember, until ~1500 the world was effectively split in half with europe and asia developing at different rates than the americas, then all of a sudden this new territory started soaking up lots of europeans whose population exploded (while the natives diminished). this is quite a curve if it takes all of this into account :P

it's also interesting that that curve takes into account war, disease natural disasters, etc. does that mean somewhere that guy has a secret file with every conflict / disease / disaster and accurate records that have been kept for all such incidents for the last ~6400 years? that's quite a record book.

oh let me guess, Saint Peter loaned him a copy of the ledger from the gates of Heaven, right?

Answer 4

I assume that with a human population curve you mean a curve representing the size of the human population over time.
Given the population of humans undoubtly has grown even exponentially why would you even expect it to be bell shaped. Doesn't make the slighest sense to me.
If your curve starts 4400 years BCE than I would suggest that whoever made that curve did not feel comfortable extrapolating numbers for times before then. I doubt there is much reliable data from there, though I can assure you that humans were around much earlier than that. Homo sapiens has been around for about 200 000 years.

Answer 5

Well, curves tend to be based on scales in large magnitudes and rely upon credible information. Recorded history is relatively modern (within 4400 years and any numbers generated before 4 M years ago would be speculative. So the curve begins when data is available and likely 'looks like' it starts at zero (in what unit? thousands? millions?) because even the thickness of the line in which the curve is depicted is arbitrary and was not considered by the person who drew the scale, when in fact maybe the curve actually starts at a few hundred thousand or 5 million. Some archaeologists make estimates based on waste found at digs and the size of excavated ruins, etc and many of these in fact predate 4400 years, so maybe the person who made this curve was not well informed?

Answer 6

The human population curve has a lot to do with environment. A population of a species will mostly be stable in a given area for the given food and predator threat. When something significant comes along that drastically changes the conditions, the population has the ability to start growing exponentially. In the case of humans, things like civilizations, medicine, farming, weapons, etc, drastically changed the living conditions. Humans stopped simply surviving based on available food and threat to injury, and started actively finding ways to increase the population.

Similar things can be seen with other animals. For example, rabbits will shoot up in numbers when human growth drives out all the predators.

Answer 7

The curve representing human population as a function of time has been approximately exponential since the invention of agriculture, about 6000 years ago. Before that, the human population was small and approximately constant for many tens of thousands of years, during the neolithic period, when people were hunter-gatherers. Agriculture allowed an exponential growth in population, as long as the resources available for agriculture were in abundance, a situation that is now coming to an end.

To use this as an argument against evolution is pretty silly.

Answer 8

A Bell curve is a description of the Normal Distribution.
As far as I know this has nothing to do with population curves.
I cannot imagine what data is used for the graph you describe.

Good luck in finding your answer !

Answer 9

Show your work and sources... i am not familiar with any "human population curve." Is that an I.D. thing?

Answer 10

What is this "human population curve"? It sound like some kind of garbage invented by some fundamentalist christian morons.
