Darren Naish at Tetrapod Zoology gives an overview of the cattle of Asia, with pictures. A couple of take home messages, for me. One is that the domestication of various bovids is pretty complex, with hybrids, feral forms, wild relatives and all combinations thereof in existence. The other is this conversation-stopping tidbit: “domestic cattle don’t need to shiver or employ other thermoregulatory tricks even in temperatures approaching -20° C”. Why not? Go read Darren’s post, and then reconsider the “fleshy dewlaps, tall dorsal ridges and other structures” that are typical of tropical types.
