Burmese Fossil Indicates Apes Arose in Asia, Not Africa

“Fossils recently discovered in Burma could prove that the common ancestors of humans, monkeys and apes evolved from primates in Asia, rather than Africa, researchers contend in a study released Wednesday.”

Right off the bat, the premise is all wrong.

It was the U.S.

Simple logic would suggest that humans arose from the place with the highest density of current population. Like China or India. Folks have been there longest and, notwithstanding catastrophe, in a macro sense, this is where the highest number should be. If mankind were 25 million years old, the population of the Earth would be in the trillions.

In my humble opinion....

Hmmm. This might explain why I like Asian food.

[ciwwaf]

Thats not how it works. Human population because it has no predators grows rapidly until it reaches it’s carrying capacity. Carrying capacity is high in a place with lots of food, living space, etc and low in a place like a desert.

You are thinking of exponential growth when population is actually logistical growth.

[April Lexington]

Could be. But, given a large enough area and the fact that any destructive threat would be localized, I would think that, over the space of a continent, the population would be densest where it is oldest. Locally, I think you are correct but, continent wide, I think the total population would be able to overcome local destructive events. Also, using birthrate data, the population should be multiples higher over a 25 million year time period. Geometric, linear or localized. We've doubled the world's population in my lifetime (according to the UN) and I'm simply not that old!

I'm curious to know if anyone has OBJECTIVELY modeled human population growth from the pre-historic period to present. If OBJECTIVE analysis could possibly be used in this highly political field, it may shed some scientific light on the theory.

[April Lexington]

Also, why would humans emerge from a desert unless stress makes them think better to survive.

[YHAOS]

Really?!

Who Knew?

[blackminorca]

Na - that monkey originally came from Massachusetts

[Candor7]

Not true, they arose in Kenya and we have one in the White House.

[ciwwaf]

Populations do not work that way.

If you want to learn more look here:

“http://en.wikipedia.org/wiki/Logistic_equation#In_ecology:_modeling_population_growth";

You are thinking of exponential growth like in bank accounts or radioactive decay. Which are very different.

[April Lexington]

Wikipedia!?! How about a scientific journal or two!

[ciwwaf]

Wikipedia is great for math and physics. Almost everyone I know uses it for engineering. and I read through that part to make sure it was accurate. A scientific paper would be debating additional variables or constants added into an equation like for over fishing.

BTW a different type of population model is used for predator/prey and looks really pretty.
the equations that are used in this video are as simple as

dx/dt = -ax + bxy dy/dt = cx - dxy

Wow! Wikipedia is the scourge of academia because it is not peer reviewed and can be manipulated for political ends. It is not academic. We flunk our students for using Wikipedia as a major source. I hope those engineers aren't designing anything I use!

Historically, on Wall Street, investments in debt and equity were made based on human instinct and judgment of human behavior (quality and success of management, etc.) Then, Microsoft perfected electronic spreadsheets. Then Quants happened and then, in 2007, Wall Street and the global financial system melted down because Quants can make spreadsheets say anything they want them to say. And.... Swiss bankers, among others, want so badly to believe, that, well, they believe. Then, $15 trillion plus in net worth evaporates because they looked at "simple formulas" instead of using their heads. Really, how can a Swiss banker EVER think an illegal alien in Southern California with no job can afford a $1 million mortgage? The "simple formula" said risk had been sliced and diced and sold off and made to disappear. Then, wham... all of the smart Quants got wiped out.

My point is, formulas don't mean diddly...
