Rodent molars are well Geared up to grind food items into modest particles.[2] The jaw musculature is robust. The lower jaw is thrust ahead while gnawing and it is pulled backwards through chewing.[three] Gnawing works by using incisors and chewing makes use of molars, however, mainly because of the cranial anatomy of rodents these feeding strategies can not be employed simultaneously and so are thought of as mutually unique.
The best impression of rodents on individuals began when agriculture commenced and people selected to live in settled houses. At that time, some rodent species moved into human dwellings, especially to consume stored grain and foods scraps also to gain from heat dwelling spaces and safety from predators.
