Forensic anthropologist Caroline Wilkenson says Mongoloids feature "absent browridges".[25] Skulls belonging to Asians and American Indians exhibit very forward-projecting malar bones and comparatively flat faces, more circular orbits than other groups, and a moderate nasal aperture with a slightly pointed lower margin.[26] Moreover, Mongoloid skulls are the most gracile in the human family. It is believed that the Mongoloid skull type is a very recent evolutionary development.[27] "The Mongoloid skull has proceeded further than in any other people."[28] "The Mongoloid skull, whether Chinese or Japanese, has been rather more neotenized than the Caucasoid or European."[28] "The female skull, it will be noted, is more pedomorphic in all human populations than the male skull." [28] "Mongoloid races are explained in terms of being the most extreme paedomorphic humans."[29] "The intuition that advanced human development was paedomorphic rather than recapitulationary and accelerated was disturbing to many Eurocentric nineteenth century anthropologists."[30] "If juvenilization was the characteristic for advanced status, then it was clear that the Mongoloid races were more deeply fetalized in most respects and thus capable of the greatest development." [30] "[R]elatively large-headed [is the] mongoloid".[31] "An interesting hypothesis put forward by paleontologist Stephen Jay Gould many years ago was that the package of the Mongoloid anatomical changes could be explained by the phenomenon of neoteny, whereby an infantile or childlike body form is preserved in adult life.[32] Neoteny in hominids is still one of the simplest explanations of how we developed a disproportionately large brain so rapidly over the past few million years.[32] The relatively large brain and the forward rotation of the skull on the spinal column, and body hair loss, both characteristic of humans, are found in foetal chimps.[32] Gould suggested a mild intensification of neoteny in Mongoloids, in whom it has been given the name paedomorphy.[32] Such a mechanism is likely to involve only a few controller genes and could therefore happen over a relatively short evolutionary period.[32] It would also explain how the counterintuitive retrousse [turned up at the end] nose and relative loss of facial hair got into the package."[32]
"Decrease unnecessary muscle bulk, less tooth mass, thinner bones and smaller physical size;"[32] this follows the selective adaptive model of Mongoloid evolution.""[32] In Ashley Montagu's list of "neotenous structural traits in which Mongoloids differ from Caucasoids", Montagu lists "Larger brain, larger braincase, broader skull, broader face, flat roof of the nose, inner eye fold, more protuberant eyes, lack of brow ridges, greater delicacy of bones, shallow mandibular fossa, small mastoid processes, stocky build, persistence of thymus gland into adult life, persistence of juvenile form of zygomatic muscle, persistence of juvenile form of superior lip muscle, later eruption of full dentition (except second and third molars), less hairy, fewer sweat glands, fewer hairs per square centimeter and long torso"[28] "Mongoloid subjects were found to have approximately 20% higher bone density at the angle of mandible than Caucasoid subjects."[33]

1. Asians are the most evolved with "a very recent evolutionary development.[29] "The Mongoloid skull has proceeded further than in any other people."
2. Orientals are the most pedomorphic of any other race, which means we retain childlike traits even in adulthood. The significance of this is that it allows our heads to grow much larger than normal allowing our brains to grow. Scientists have accounted pedomorphsis as the reason why humans have such large heads and also a theory on why the Neanderthal did not kill Homo-Sapiens because of our smaller and "cuter" appearance.
3. Evolutionary advancement has been proven to be pedomorphic , considering that Asians are the most pedomorphic of any race its reasonable to conclude that Asians are further along on the evolutionary line than any other race.
