Are people that live closer to the equator smaller?

cool easier with less surface area? you have it backwards - more surface area means more cooling (more sweat leads to more evaporation of water which removes thermal energy)

No, they are not. I can see the logic behind your answer, but gravity is a constant any where on the planet. So, people should have the same force acting on them.

If your talking about a gene related issue, I do not know of any geogeneaology issues that surround organisms lining the equator.

You have a good theory, but as another answerer said, gravity is the same all over the earth. It's genetics, not region that has to do with the size of the person.

:)

people are darker at the equator.

smaller, that would be harder to prove.

peple wo live in the polar regions are rounder for heat savings, so maybe your premise is off.

You're thinking of Bergmann's Rule, which applies to those warm-blooded animals that don't have fire and wear clothes.

no, the watousi tribe in africa are the tallest people in the world, where you live has nothing to do with you physical body

im tiny and i live no where near the equator

No.
