Why so many down syndrome traits appear in east Asians? Down himself noted that from the start, so he called it mongol idiocy, but not before nor after abandoning this term we still have no explanation why this genetic disorder gives mongoloid traits to a carrier

Good question. In Dutch, people with Down syndrome are literally called “Mongols”, but I’ve never given it a second thought as to why.

they aren't mongolid traits. both mongoloids and those with that chromosomal disorder share neoteny.

Downs occurs when then chromosomes do not fuse, resulting in a 24rd chromosome similar to the other apes. Downs syndrome are simply more ape like characteristics. It is literally devolution.

23rd... not 24th, but yes.

No one likes to point this out because 1) Westerners and especially Americans are largely fundamentalists who hate science. And 2) its rude.
