dog : a highly variable domestic mammal (Canis familiaris) closely related to the gray wolf — Webster   See also   OneLook


Domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species) is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. — Wikipedia

Mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as “mastology,” “theriology,” and “therology.” The major branches of mammalogy include natural history, taxonomy and systematics, anatomy and physiology, ethology, ecology, and management. — Wikipedia

    When I was sixteen, I trekked for miles up untraversed trails in Sonoma County, California, in search of mountain lion dens and sites where cougars eat their prey. (Mountain lions, pumas, panthers, and cougars are all names used for this same species.) As an intern for the Living with Lions project, I studied how humans and top predators can coexist in shared areas.

    Since the beginning of human creative activity, nature has served as a source of inspiration. That continues to be true for Saikat Basu, an assistant professor in South Dakota State University's Department of Mechanical Engineering, who took inspiration from a pig's snout to investigate ways to improve air filtration.
