Who was the original Rh- species?

Why are hazel eyes so frequent in Rh(D) negative individuals?

Did we inherit red hair, blue eyes and pale skin from Neanderthals?

How to put everything into perfect wording, I am not always sure, so I will simply blurt out possibilities that haven’t been examined:

We Rh negatives tend to have certain traits that were common among the Neanderthals.

What did Neanderthals REALLY look like?

Why?

Is it that for some reason being hybrids tends to show recessive genes rather than not?

What I mean is this:

You may not have red hair.

It could be strawberry blond, auburn or black with a reddish shimmer when the sunlight hits.

Your eyes may not be brown or green, but hazel or possibly central heterochromia instead if hazel won’t apply.

What is the difference between hazel eyes and central heterochromia?

In that case, you have several colors shine through, including the recessive ones.

Usually people have green, brown or blue eyes, rarely hazel.

Usually people don’t have reddish hair as it recessively disappears.

Yet we seem to also have different hair colors on different parts of our bodies.

Rh negatives may have an elevated frequency of central heterochromia

What matters is what is “underneath the hood”.

It determines much of our health predispositions, overall well being and ability to navigate through life.
