genus Bos

Putnam has listed "acid" as a natural kind term, which stands for several compound substances that have different chemical formulas.(6) Kripke thinks "common names" is an expression "quite appropriate" for natural kind terms, and uses "cow," which stands for the mature female of the genus Bos, as an example.(7) Unless they were to change their views in a drastic way and consequently greatly reduce the power of their theory Kripke and Putnam, I assume, would not accept the view that objects can be in only one kind.

Likewise, cow (the mature female of the genus Bos) is a natural kind (per Kripke), but I have every reason to say that a species of the genus Bos is also a natural kind.

The new Bovini remains, referred to the genus Bos, are recovered from the Sardhok Pleistocene of Northern Pakistan.

Originally, all Bovini employed the genus Bos. Earlier many bovine forms like Leptobos, Bison, Eobison and Bibos were considered the subgenera of Bos (Pilgrim, 1939).

Combined with other bovine Cyt b sequences cited in GenBank, the phylogenetic trees of genus Bos were reconstructed by neighbor-joining (NJ) and maximum parsimony (MP) methods with Bubalus bubalis as outgroup.

The NJ and MP phylogenetic trees of genus Bos (Figures 2 and 3) were reconstructed with Bubalus bubalis (Accession No.
