Jacques Cauvin has argued that Neolithic animal symbols, with early art depicting figures such as bull gods, derive from the critical importance of domesticated mammals ...
Non-human mammals form a large part of the livestock raised for meat across the world. They include (2011) around 1.4 billion cattle , 1.2 billion sheep , 1 billion domestic pigs , [ 7 ] [ 11 ] and (1985) over 700 million rabbits.
Truly fossorial mammals have short, stout legs as strength is more important than speed to a burrowing mammal, but semi-fossorial mammals have cursorial legs. The front paws are broad and have strong claws to help in loosening dirt while excavating burrows, and the back paws have webbing, as well as claws, which aids in throwing loosened dirt ...

The archive of number of mammals on earth is constantly growing, but is currently set at 6,495 different mammal species including recently extinct. [2] There are 5,416 living mammals identified on earth and roughly 1,251 have been newly discovered since 2006. [ 2 ]
Several important fossil mammal discoveries have been made that have led researchers to question many of the relationships proposed by McKenna and Bell (1997). Additionally, researchers are subjecting taxonomic hypotheses to more rigorous cladistic analyses of early mammal fossils.
Livestock make up 60% of the biomass of all mammals on earth, followed by humans (36%) and wild mammals (4%). [ 142 ] [ 143 ] In November 2017, 15,364 world scientists signed a Warning to Humanity calling for a drastic reduction in per capita consumption of meat and "dietary shifts towards mostly plant-based foods".

Figure 1:In mammals, the quadrate and articular bones are small and part of the middle ear; the lower jaw consists only of dentary bone.. While living mammal species can be identified by the presence of milk-producing mammary glands in the females, other features are required when classifying fossils, because mammary glands and other soft-tissue features are not visible in fossils.
