Northern Chinese are tall - perhaps, due to wheat?

In China, as in many countries, the north-south divide runs deep. People from the north are seen as hale and hearty, while southerners are often portrayed as cunning, cultured traders. Northerners are taller than southerners. The north eats noodles, while the south eats rice—and according to new research, when it comes to personality, that difference has meant everything.

A study published Friday by a group of psychologists in the journal Science finds that China’s noodle-slurping northerners are more individualistic, show more “analytic thought” and divorce more frequently. By contrast, the authors write, rice-eating southerners show more hallmarks traditionally associated with East Asian culture, including more “holistic thought” and lower divorce rates.

Kerala and Brahmin descent from Aryan and mixed races

People with fairer skin in Kerala are mostly due to mixing of Arabs and local population (among Muslims) and Portugese and local population (among Christians).

The girls/women in north Kerala are more beautiful due this mixing with Portuguese, Jewish and European traders.

Hence, one can find many Malayalees are fair in color. The darker Malayalees are from Dravidian descent.

Also, complexion gets fairer as one moves from south to north kerala. (My note: As one moves further north into Karnataka, Goa, Konkan - the complexion gets fairer, perhaps, it has to do with this Aryan descent along with this belt.)

Most south Indian Brahmins are descendants of Aryans. Few of the Brahmins were converted from local Dravidians. Hence, Brahmins are fairer in color compared to normal south Indian population and also of higher intellect.

Similarly, Yadavas have migrated from the north (?). Perhaps, they are of aryan descent too.

Height research - very good discussion on a blog

Genetics and Nutrition are important in determining height

North Koreans are shorter than South Koreans

Japanese height has increased significantly over the last 100 years.

If economic development and nutrition are important why are many Africans taller than Japanese.
