WHITE PEOPLE: Extinct hair/eye colors?

Southern G

I heard that some people have violet eyes. Maybe it's very rare today, but probably it was pretty common before. Same thing with red hair, maybe it was common before, but they are both almost extinct now.

How do we know if there are other extinct hair/eye colors?

Answer
Red hair has never been common, but it's nowhere near extinction. I'm related to tons of redheads. As for violet eyes, it seems like they're really just a dark enough blue that they appear violet. That's also very uncommon, but there are still people with that deep shade. It would be very interesting to discover extinct colors, though.

What hair color is the least common naturally?

LP's Mommy

Ive been told its red.

Answer
i would think red too... idk...

heres what i found

The red-hair gene is recessive and only four percent of the world actually carries the gene. Due to its recessive nature it becomes diluted when carriers reproduce with those who have the dominant hair, therefore putting redheads on the endangered list. However, many scientists are skeptical of extinction, stating that four percent of 6.4 billion people is too large a figure to wipe out in the next ninety-five years. Dr. David Pearce of the University of Rochester of Medical Center also points out that while the red-hair gene âwill dilute and become rare, but there are a variety of other factors that can change hair color that are not really understood well right now."

are redheads really doomed to extinction?

dylan t.

Answer
The gene is incomplete recessive and redheads are a small minority of the human population so yes, if they breed freely with people with different hair colors eventually they'll disappear. Some people will still carry the gene but they'll have auburn hair or strawberry blonde hair, not red hair.

What color was Tyrannasaurus Rex? Why did they go extinct?

Answer
>>>>>What color was Tyrannasaurus Rex?

We have no absolutely no way of knowing. It almost certainly varied with the age of the animal.

The young animals almost certainly had feathers, and given their small size it seems reasonably that both the feathers and the skin would have been dark brown or black to enable them to heat from sunlight. The addittion of spots or stripes would add in hiding. The young of most large birds and mammals today are stipe dor spotted so it seems reasonable to assume the same for tyrranosaur chicks.


The adults seem to have lacked feathers, at least for the most part. In that respect they seem to be like elephants rhinos, whales and other large mammals where the young retain at leat sparse hair that is almost totally absent from the adult.

What colour the adults were we simply canât know. Animals of that size generally have little use for camouflage colouration so they can be whatever colour they like. The big question is how much of a role vision played in courtship. If tyrannosaurs were like modern birds we would expect the males at least to have extremely brightly coloured heads at the very least.

So an olive grey Tyrrannosaur with a bright blue head and big red circles under the eyes is no less likely than any other colour scheme.



Cellar door said âThey were just large versions of the lizards we have today.â


They most certainly were NOT large versions of the lizards we have today. They are only very distantly related to modern lizards. The closest living relatives are, not surprisingly, birds.


We arenât entirely certain what the lifestyle of a T. rex was, they seem to have been a combination of predator and scavenger. In terms of lifestyle the closest living comparison would probably be a lion or hyaena.

They were in no way lizard-like.

>>>>They went extinct because of a meteor

That is one theory, but one that is rapidly losing credibility. There were probably multiple factors leading to the mass extinction that took T. rex along with numerous other species. A comet or meteor impact just doesnât explain all the observations
