So, living at the equator, we got

Below me is the equator and the start of my journey with wind.

So it's like the equator or the lines of longitude.

Warm air rises from the equator and hits the tropopause.

I was keelhauled the first time I crossed the equator.

And more recently you can see it's just around the equator.

It's out in the middle of the Pacific, right around the Equator.

The cold waters here allow them to survive on the equator

These are some of the richest seas on the equator

Levelling New York City perhaps, or sinking the Rock of Gibraltar.

I thought he'd wait for you till there was ice on the equator.

He knew that darkly pigmented peoples were found close to the equator

looking at the equator, we were bombarded by high levels of ultraviolet radiation.

The winds I followed from the equator have taken about 14 days to enter the last of the big wind cells.

Low pressure air rises from the equator and meets high pressure air from the poles.

In those early days of our evolution, looking at the equator, we were bombarded by high levels of ultraviolet radiation.

The doldrums are basically a narrow strip of complete calm, five to ten degrees either side of the equator.

These six wind cells constantly try to balance the temperature between the freezing poles and the sweltering equator.

If it didn't exist, the poles would be 25 degrees colder and the equator would be 14 degrees hotter.

He knew that darkly pigmented peoples were found close to the equator lightly pigmented peoples, like himself, were found closer to the poles.

What's very, very important here is that the earliest humans evolved in high UV environments, in equatorial Africa.

They had discovered the Galapagos 600 miles off the coast of South America right on the equator the Galapagos are a small group of a dozen or so islands alone in the vast Pacific Ocean

Major moves, outside of our equatorial homeland, from Africa into other parts of the Old World, and most recently, into the New World.

It then slides north and south before sinking back down to Earth and returning to the equator as the winds we feel on land or sea.

So in Egypt, in Aswan down in the south, they regard the sun as being vertical this is near to the equator and they worked out how far away from the vertical the sun was if they measured it from the north of Egypt, in Alexandria, which is on the Mediterranean coast.

And even though Mount Chimborazo isn't the tallest mountain in the Andes, it's one degree away from the equator, it's riding that bulge, and so the summit of Chimborazo is the farthest point on Earth from the center of the Earth.

We evolved as a species near the equator, and so we're very well equipped to deal with 12 hours of daylight and 12 hours of darkness.

Galapagos lies remote, 600 miles off the coast of South America astride the Equator a scattering of 13 main islands with more than 100 islets, rocks and reefs

So, living at the equator, we got lots and lots of ultraviolet radiation and the melanin this wonderful, complex, ancient polymer compound in our skin served as a superb natural sunscreen.

And so when we look at a map of skin color, and predicted skin color, as we know it today, what we see is a beautiful gradient from the darkest skin pigmentations toward the equator, and the lightest ones toward the poles.

Distribution Plants in the family are distributed on all the southern continents South America (1 sp., Apodasmia chilensis ), Africa south of the Equator and including Madagascar (about 330 spp.
