Awesome! I saved a few of my fav phenotypes... You prefer only Asian phenotypes? OK! Which are interesting or exotic type for you?

Indeed. “Polynesids?” Classification of humans into phenotypical and genotypical groups can be useful for some purposes—targeted “designer drugs” for various diseases, for instance, or police identification of murder victims found in Chicago’s forest preserves. Yet any full taxonomy would have to catalog thousands of entries, for a human population that’s really more or less a continuously graded carpet around the globe, now traveling far from their places of birth on modern mechanized conveyances. All of them seem to have two eyes, two ears, nose, and mouth. Although I must admit I lost my head hair a long time ago, and wear a hat now. Nothing like a sunburn on the scalp to teach me a lesson!
~ Diamond’s question, “Why bullshit?” deserves an answer, however. This is due to a history of racist thought influencing the rather unscientific, ad hoc categories found on the web site citation in this thread. See the American Anthropological Association’s 1998 statement on race for details. And the AAA statement itself was a belated, tepid response to criticisms of anthropology some human groups had raised.
One nice experiment asked participants from a mix of racial backgrounds to order a set of 30 skin color tiles in sequence from lightest to darkest and draw the “color line” between those they would classify as “white” and those they would deem “black.” No two participants ever came up with exactly the same sequence, as while some tiles were clearly near the light end of the scale, or near the dark end, many of the tiles were about equally dark when placed side by side, just differing in hue. The “color line” varied as well, the median choice, 13th tile and lighter being “white.” Dark-skinned people usually drew the line at a darker shade than the light-skinned folks did.

Shit anthrotard site full of high-fantasy phenotypes and useless, inaccurate morphs. I wouldn’t say so much “inaccurate” as simply “pointless.” A human being starts out as a single cell, equipped with a genome of about 2 trillion Daltons molecular weight, with ≈19000 coding genes, each of which specifies a protein. This information store is supported by a machinery of DNA and RNA polymerases, ribosomes, and endoplasmic recticulum, and communicates with the outside world through a membrane studded with receptors and gated channels made of protein.
The main order of business here is electricity. To keep the new human alive, reduced electrons from food must be pumped through the system, oxidized by O2 from the air, and exhausted to power the activities of the cell and carry away the entropy that would otherwise choke it. This happens on the membranes of yet another intracellular machine, the mitochondrion, where electrons from metabolism of food—in the form of glucose, a sugar—are transported by a set of proteins called cytochrome P.
The initial cell divides about 50 times to yield the 2^46 = 70 trillion cells that make up a completed human, as an embryo arraying in three layers according to the triploblastic animal plan and then segmentally, head to tail, as dictated by concentration gradients of hormones which the homeobox genes code for, and all switched on in the correct order as if we were a spacecraft on a mission. The first 9 months we live as obligate parasites on our mothers, plugged into these ladies’ uteri by umbilical cords the way Richard Gordon in his spacesuit was hooked up to Gemini 11 back in September 1966.
Finally, we’re born, souls readied in our survival capsules—our bodies—for an expedition on planet Earth that might last more than 100 years. As the deck is shuffled every generation, each human being carries a unique combination of genes, never to occur in another human however long the cosmos lasts, and experiences a unique environment no one else will ever face.
Externally, the nose might be flat, short and broad, the better to dissipate tropical heat, or long, narrow and hooked to throttle and warm the inbreathed air of a northern dweller. The skin, dotted with the pigment proteins xanthin and melanin, can vary from a milky pinkish-white to nearly jet black, depending on how strong the ultraviolet flux from our planet’s star is, in the region where that person’s ancestors evolved. These UV rays make vitamin D but also destroy unprotected skin cells if at high levels; hence the pigments.
Entropy, however, overtakes every living organism in the end, so that it dies. Question is, shall we be resurrected? Only God can save us from Death and Hell, the monstrous engines of Satan we hope are slated to perish in the lake of fire at the judgment, freeing us for eternal life. But I’ve reached a religious question I must leave the reader to decide, since I don’t know the answer.
The web site at issue is off the air, however. Racism is going out of fashion, I suspect. Looks like it had pretty pictures of young faces—I’m not a young buck anymore—but with a lot of baloney and funny monikers attached to its supposed “phenotypes.” Transmediterranids, anyone? I was thinking about a Tyrannosaurid from the late Cretaceous, just before that asteroid slammed into its savanna:

Awesome! I saved a few of my fav phenotypes... You prefer only Asian phenotypes? OK! Which are interesting or exotic type for you?I'm most into & knowledgeable about Asian and European phenotypes in general, though I try to learn a little of everything as well.. As far as "exotic" goes South Asian and Middle Eastern types usually impress me in that category, such as Indids and Iranids taxonomically speaking. For Euro types here are a few of my favs:

I think I’ll take the “West Alpinids.” I’m from a rather montane area myself, mean elevation of the country around here 6000 feet, with cold, snowy winters and a dry summer. But I’ve never been to the Alps. Too bad, when I spent some time knocking about Mainz-Wiesbaden, Germany and the Alps were just 200 miles away.

It can be found in Asia too. The names are simply quite artificial. en.wikipedia.org/wiki/Alpine_racearktos.boards.net/thread/530/alpine-race

The Alpine race is quite large. It can be found in Asia too. The names are simply quite artificial. Yeah. I’ve always wondered how those Tibetan Buddhist monks can stand living at 17000 feet in the valleys below the Himalayan ridgeline. The air pressure up there is only 55kPa, half what it is at sea level, and I’m sure I’d pass out within the hour if I tried to ascend to that monastery. And it’s pretty damn cold, too, even in the summer months at night. This altitude was the ceiling for WWI biplanes like the Sopwith Camel; their engines would die if they went any higher.
I agree the nomenclature’s all artificial. None of it appears in biochemistry textbooks, which treat humans as a single animal species, or in anthropology, which does recognize differences between human groups but uses a less rigid classification scheme which considers culture alongside physical traits.
Any two people will share about 99½% of their DNA in common, the ½% variant usually found in non-coding stretches of the chromosomes. Of course, change of a single base pair can make a huge difference; just one base pair causes sickle cell, where a polar glutamic acid substitutes for a nonpolar valine in the α-hemoglobin chain, altering the molecule’s conformational shape so that the red blood cells wrinkle up when deoxygenated.
Yet evolution is conservative. Dicking around with the genes for Acetyl-CoA or Cytochrome P oxidase or sodium channels is dangerous, as these enzymes are vital to life. Our cytochromes aren’t much different from those of paramecia—the tiny cells shaped like house shoes you see swimming in pond water under the microscope. Genes that code for body plan or skin color can flex a bit more, yet the drug thalidomide was causing the birth of legless, armless babies in the 1960s before it was banned. Mutations in the melanocytes that produce our skin pigments cause the dreaded melanoma, a cancer which metastasizes quickly to lungs, liver and bones, killing a million people worldwide each year.
