Interesting...

Genes/phenes pingaroonie...

I thought this was going to be an interesting story about Helen Thomas, sorry.....

[G Larry]

Rather argues against evolution doesn’t it?

[Natufian]

Fascinating. Thanks for posting.

[blam]

The 2nd oldest, eh?

It must be the: " I have a headache tonight" gene.

[Pharmboy]

You're quite welcome. This sentence from the article stymied me: "The researchers say that although the mutation is found in vastly different ethnic populations,..."

Turks, Jews and Arabs are not "vastly different;" they all appear to have originated in the Near East. Perhaps this mutation is also present in, say, Hmong tribesmen or Orkney Islanders, but that is not said, and I do not think that is the case.

Have they discovered ANY mutation that is NOT destructive? One, just one.

[Pharmboy]

There are many genetic mutations that are beneficial (they have recently found ones that appear to make us smarter); and it’s always not so easy to tell, since single doses of certain recessive genes appear to be beneficial although double-doses are fatal (cystic fibrosis and possibly Tay Sachs). Most mutations are actually neutral, some are bad and rarely they are good.

The one (or several, or many?) that makes humans less lactose intolerant over time?

The “sickle cell” mutation is one.

Individuals with one allel are more resistant to malaria than those without the mutation.

[Pharmboy]

Indeed...as is thalassemia...other examples where one gene is good, but two genes bad.

Thanks Pharmboy. ...investigators described the mutation in people of Arabic, Turkish and Jewish ancestry. It causes a rare, inherited vitamin B12 deficiency called Imerslund-Gräsbeck Syndrome (IGS). To all -- please ping me to other topics which are appropriate for the GGG list.

[Pharmboy]

Ha! That actually might be the oldest...

[SunkenCiv]

I’m not sure there is such a thing. I mean, sure, we view Helen Thomas topics in the same frame of mind that we drive slowly past accident scenes, but...

[Moonman62]

There are many known instances of genetic duplications that are beneficial.

[null and void]

How about the mutation that allows primates to distinguish between red and green?

[huldah1776]

How is the age of a mutation equated?

[Bellflower]

According to evolutionist mutations are at least a major reason for all the vast changes of all organisms from just one cell (even one cell is vastly and incredibly complex) all the way up to man. I don't get it, for you evos, how do you justify distinguishing between mutations and all of the rest of cellular DNA labeled as not being a mutation?
