The Simian Crease

Down’s and Asians. Native Americans are of course ultimately of Asian origin.

Following up on this, more information; well, well, well

In humans, a single transverse palmar crease is a single crease that extends across the palm of the hand, formed by the fusion of the two palmar creases (known in palmistry as the "heart line" and the "head line") and is found in people with Down syndrome. It is also found in 1.5% of the general population in at least one hand.
Because it resembles the usual condition of non-human simians, it is also known as a simian crease or simian line, although these terms have widely fallen out of favor due to their pejorative connotation.
…it is more common among Asians and Native Americans than among other populations…

Very interesting.  In a sense, if the original hypothesis (linked to above) is true, East Asians can be considered functionally equivalent to very high functioning Down’s syndrome patients, the oxymoron of “high IQ retardates.” It would be useful to compare gene expression profiles and cell signaling in East Asians to Down’s syndrome patients.

We could also hypothesize that East Asians are a form of semi-autistic highly attenuated idiot savants, with an emphasis on spatial, mathematical intelligence and focused k-selected behaviors, with defects in most other aspects of the human experience - creativity, for example.

Please note that this sort of hypothetical rumination is not meant to be in any way hostile to East Asians.  However, from the standpoint of "human biodiversity" - that the "movement" proclaims it is ever so interested in - one would think that the possibility that a major racial group is akin in many ways to Down's syndrome is something that should be investigated.  From a practical standpoint, any potential findings could possibly be used to devise novel therapies for Down's patients or for others afflicted with cognitive and/or behavioral deficiencies.  If such people can be brought up closer to normal human (or at least East Asian) levels of function that would be a vast improvement in their quality of life.  One could focus on differences in gene expression and cell signaling between Asians and retards that allow East Asians to exhibit a "high IQ" despite the possibility of evolved deficiencies that overlap with Down's phenotypes, and leverage those differences to mimic these Asian patterns in retarded patients.
