I think it has to do with natural resources and outside influences. Tribes in Africa tend to be small due to food, disease, and other dangers of jungle living, leading to an isolationist lifestyle. This way of life tends to stagnate.

People that moved to temperate zones had more resources as the land is easier to work with, less disease and predators, and because moving around is easier they had more outside influences.

That makes sense. Too busy dealing with food and shelter demands on a daily basis.

I've often thought there would be no civilization as we know it if not for nagging women.

Cave woman: I'm sick to death of trying to keep this fvcking cave clean!!! Can't we figure out a better way? :twisted:

Cave man: Oh Fvck you, it's good enough! :awe:

Because the Mercator projection preserves shape but not area. Many rumor it also has to do with white colonial rule trying to add importance through false size on this projection, which is still the standard in schools today.

For a more accurate projection that preserves size:
http://www.petersmap.com/

or check out the Mollweide/Eckert here:
http://www.equal-area-maps.com/mollweide.php

Unfortunately there isn't a way to preserve all four aspects (shape, distance, area, direction) which is why there are so many projections that will accentuate one or two of the 4 aspects. Mashing a round surface onto a flat surface will always have distortion (3D-->2D plane).

I prefer the Mollweide projection to the Peters. The Peters distorts the shapes so much more just to have parallel longitude lines. Also, it makes Canada actually look smaller than the US.

The Peters Projection should have been made the standard years ago. Not sure why we cling to these old standards, that do nothing to reflect actual land area.

Shall we mention that despite its massive land area - that a huge chunk of Africa is either inhospitable and completely barren desert, or really dense jungle teeming with dangerous wildlife and disease?

If that's the true size of Africa, why is it always so small on all maps?

On google map, America is more than half the size of it, not a third.

Because the earth is round, and method of representing its surface on a flat drawing will always introduce some form of distortion. The main types of distortion are shape, area and length. Different methods of drawing maps have been designed to minimize different types of distortion, or to alter the balance of distortions for special purposes.

The most popular method of drawing maps for "general" use is the Mercator projection. This is popular because it is very simple, and minimizes distortion of shape and distance (along the lines of latitude and longitude). The problem with the Mercator projection is that it severely distorts areas - the further from the equator you get, the more the area is magnified. This means the ice caps (and arctic countries) appear massive.

So, compared to Africa (most of which is close to the equator), the USA which is mostly further North, appears massively magnified on Mercator projection maps.

There are many different "equal-area" projections available for maps, which preserve areas, but tend to distort shapes or distances.

e.g. The Gall-Peters projection which preserves area and preserve straight lines of longitude/latitude, but distorts shape.
Mollweide projection which gives a different type of shape distortion.

There are more complex versions like:
the interrupted Good homolosine projection which is a "cut" version of the Mollweide projection, designed for less distortion of continents, at the cost of "cutting" the oceans.

This map is stupid.

Show me an overlay of the entire North American continent (Canada, USA, and Mexico) and Africa for comparisson. Im betting they are very close is size.

It's called a fucking globe.

Africa should be bigger than all other land mass combined, if size were based off of prevelance of AIDS.

So why they comparing countries to a continent? They trying to say it's a country again?

Don't kid yourself...you will be back the minute someone posts a thread calling an obese whale of a woman "fat." You can't help it.

But go ahead and have some unprotected sex in sub-saharan Africa.

uhhhh... no.

Africa is the world's second largest continent. North America isn't close in size at all.
