Genetic Studies
The Sinhalese are not a distinct group that is entirely or even mainly of Indo-Aryan origin, which is itself a linguistic categorization and not a palpable 'racial' group.
As the sinhalese originate from India they, like other Indian tribal and caste populations, derive largely from the same genetic heritage of a southern asians and western asians in the Pleistocene. They are likely to have have received limited gene flow from external regions since the Holocene. [9]
According to genetic evidence, the Sinhalese have their origins in South India and North-East India, particularly Tamil Nadu and Bengal . Due to relatively easy access from South India and Tamil workers being brought from South India under British rule, mixing of the Tamil and Sinhalese groups has been occurring for many generations. The Sinhalese and Sri Lankan tamilshave been in close proximity to each other historically, linguistically, and culturally for over 2000 years. This explains why they share a common gene pool of 55%.[10]
A genetic admixture study found the sinhalese had the greatest contribution from South Indian tamils (69.86% +/- 0.61), followed by Bengalis from the northeast India (25.41% +/- 0.51). Similarly, Sri Lankan Tamils have a greater contribution from the Sinhalese of Sri Lanka (55.20% +/- 9.47) than Indian Tamils (16.63% +/- 8.73).[11]
This is also supported by a genetic distance study, which showed low differences in genetic distance between the Sinhalese and the Tamil, Keralite and Bengali volunteers.[12] D1S80 allele frequency (A popular allele for fingerpriting) is also similar between the Sinhalese and Bengalis, suggesting the two groups are closely related.[13] In additon, the Sinhalese and South indian tamils have similar cultures in terms of kinship classification, cousin marriage, dress and housing.[14]
A 2004 biomedical central study found the frequency of the average proportion of mtDNA gene flow from West Eurasia in the Sri-Lankan population to be 15%[15]. This proportion is similar to Central, South (23%, 11% and 15% in Maharashtra, Kerala and Sri Lanka, respectively) and East Indian groups (13% in Uttar Pradesh and around 7% in West Bengal and Bangladesh).
Two studies on blood genetic markers found no significant genetic difference between the Sinhalese and Sri Lankan tamils.[16]. A study looking at gentic variation of the FUT2 gene in the Sinhalese and Sri Lankan tamil population, also found similar genetic backgrounds for both ethnic groups. With little genetic flow from other neighbouring asian population groups.[17]Studies have also found no significant genetics difference with regards to blood group and single-nucleotide polymorphism between the Sinhalese and Sri Lankan Tamil population.[18][19]Thus, the evidence suggests that the legend of the sinhalese being the descendents of Prince Vijaya and his companions may not be true, or that the genetic contribution by Prince Vijay and his companions has been erased by the contributions of other population groups, such as the tamils and bengalis, over 2000 years.
A study in 2007 found similar frequencies of the allele HLA-A*02 in Sinhalese (7.4%) and North Indian subjects (6.7%).HLA-A*02 is a rare allele which has a relatively high frequency in North Indian populations and is considered to be a novel allele among the North Indian population. This suggests possible North Indian ancestry for the Sinhalese.[20]
