主题：【原创】南亚一瞥：印度斯里兰卡游记 （1/4） -- 顾剑

Most contemporary anthropologists classify Indians as belonging to one of four major ethno-racial groups, which often overlap with each other because of a continuous process of racial admixture: Caucasoids, Australoids, Mongoloids and Negritos. The Caucasoids are largely confined to the north and generally speak Indo-Aryan languages; Australoids are found in the south and generally speak Dravidian languages; Mongoloids are largely confined to the Northeastern region of the country and for the most part, speak Tibeto-Burman languages; and Negritos are found on the Andaman Islands located on the southeastern side of the country. These speak a group of languages known as Andamanese and Ongan languages, linguistic isolates not related to any known languages. And finally, Austro-Asiatic languages are spoken by only tribals or Adivasis, who can be of either Australoid or Mongoloid racial stock.[10]
