Over breeds of cattle are recognized worldwide, some of which adapted to the local climate , others which were bred by humans for specialized uses. Cattle breeds fall into two main types, which are regarded as either two closely related species , or two subspecies of one species. Bos indicus or Bos taurus indicus cattle, commonly called zebu, are adapted to hot climates and originated in the tropical parts of the world such as India, Sub-saharan Africa, China, and Southeast Asia. Bos taurus or Bos taurus taurus , typically referred to as "taurine" cattle, are generally adapted to cooler climates and include almost all cattle breeds originating from Europe and northern Asia.

Tama-what now? An antelope-like species so elusive that no scientist has ever seen one in the wild and no camera trap has captured any images of it since Asian wild cattle are species with stories that capture the imagination. They also need our help. Up until the 16th century, 13 species of wild cattle lived across Asia, Europe, Africa and North America. Today, only 11 species are still around.

This population shows heterogeneous morphology, both in body type and pigmentation. Once used as draught animals by the local farmers, they were abandoned around the s due to changes in the economy, and since then have lived as feral populations. The stringent SNP selection we applied resulted in increased heterozygosity across all populations studies, compared with the full panel of SNP, thus reducing the impact of ascertainment bias and facilitating the comparison of divergent breeds of cattle. Our results showed that Hong Kong feral cattle have relatively high levels of genetic distinctiveness, possibly due to the low level of artificial selection, and a likely common ancestry with wild species. We found signs of a putative taurine introgression, probably dating to the import of north European breeds during the British colonialism of Hong Kong.
They are well adapted to withstanding high temperatures, and are farmed throughout the tropical countries, both as pure zebu and as hybrids with taurine cattle , the other main type of domestic cattle. Zebu are used as draught and riding animals , dairy cattle , and beef cattle , as well as for byproducts such as hides and dung for fuel and manure. The scientific name of zebu cattle was originally Bos indicus , but they are now more commonly classified within the species Bos taurus as B. Zebu cattle are thought to be derived from Indian aurochs , sometimes regarded as a subspecies , B. Phylogenetic analysis revealed that all the zebu Y-chromosome haplotypes groups are found in three different lineages: Y3A, the most predominant and cosmopolitan lineage; Y3B, only observed in West Africa; and Y3C, predominant in South and Northeast India.
