Andaman cattle is a precious indigenous livestock species endemic to Andaman and Nicobar
Islands, India. Till date, origin and genetic makeup of the breed which is warranted for
breed conservation is not known. Moreover, the spread of zebu cattle from Indus valley to
different parts of Island Southeast Asia (ISEA) is not properly understood. Here, we report
the genetic diversity, population structure of Andaman cattle and their evolution in the context
of epicentre of zebu domestication and ISEA. High genetic diversity in complete mitochondrial
D-loop sequences indicated the ability of the breed to withstand impending
climate change. Total 81 haplotypes were detected and all of them except three belonged to
Bos indicus. The presence of taurine haplotypes in Andaman cattle indicate introgression by
European-derived cattle. A poor phylogenetic signal of Andaman cattle with genetic affinities
with cattle of Indian subcontinent and ISEA was observed. The poor phylogenetic structure
may be due to multidirectional gene flow from Indian subcontinent and ISEA, with which
Andaman shares a close cultural and trade relationship from Neolithic age. We hypothesize
that Andaman cattle is the outcome of Neolithic diffusion from centre of zebu domestication
along with multidirectional commercial exchange between Indian subcontinent and ISEA.
