Llamas and alpacas have provided the peoples of Peru and Bolivia with hides, fleece, meat, and milk since at least 3500 b.c.e. Despite the lack of fossilization of the intestine, microbial evolution of the intestine can be inferred from the interrelationships of present animals, microbes and probable foodstuffs. Mammals are metagenomic, in that they’re composed of not only their own genes, but additionally these of all of their associated microbes. Gut microbiota has co-diversified as mammalian species have advanced. Recent research indicate that adaptive divergence between mammalian species is formed in part by changes within the gut microbiota. The house mouse may have advanced not only with, but in addition in response to, the unique bacteria inhabiting its intestine. Mammals are distinguished from other vertebrate animals by a number of distinctive options.

The young lick the milk from a mammary patch on the mom’s belly.

Hair or fur helps mammals survive in cold climates by insulating their bodies. Non-human mammals play a wide variety of roles in human tradition.
Compared to placental mammals, the milk of marsupials changes greatly in both production rate and in nutrient composition, because of the underdeveloped young. In addition, the mammary glands have more autonomy permitting them to provide separate milks to young at different development phases.

They are the preferred of pets, with tens of tens of millions of dogs, cats and other animals together with rabbits and mice kept by families around the world. Mammals corresponding to mammoths, horses and deer are among the earliest subjects of art, being present in Upper Paleolithic cave work corresponding to at Lascaux.
