Why do humans have more whites visible in the eyes compared to other species?

After humans split ways with proto-chimps, we developed a mutation that turns the whites of the eyes... well, white. In apes the sclera (the part of the eye that is white in humans) is actually dark, but every now and then a chimp is born with white sclera, and these individuals look eeriely human.

So, why did this mutation become so popular among humans? A common explanation is that it allows us to see where someone is looking much more accurately, from a longer distance, and even if the head is not moved at all. Of all the apes, we have the most need to communicate and cooperate on several levels. We also communicate the most with our eyes, with the direction of the gaze alone, starting even with small babies. That's why we need a clear contrast between the iris and the sclera.

Its said that all blue eyed people share the same ancestor because of a mutation. Would this be the same for everyone(which IS basically everyone) with the white sclera?

Eye color isn't hereditary.
So no.

We are all related through one female and one male tens of thousands of years ago, known as Mitochondrial Eve and Y-chromosomal Adam. Eve lived about 150 000 years ago and Adam 60 000 years ago. Though humans probably had white sclera long before either of them.

That diagram is a gross simplification. It completely ignores the Blue-Green gene and all of the currently unknown genetic factors that produce hazel, gray and black irises.

Correct. It's for communication.
