transition from nomadic hunting and collecting to sedentary agricultural practices, human beings grew to become a dependable source of shelter and foodstuff for those species obtaining the innate genetic and behavioral abilities to adapt to man-made habitats. The influence of such species on human populations ranges from inconvenient to deadly. Crops are destroyed prior to harvest; saved food items is contaminated by rodent waste; h2o-impounding constructions leak from burrowing; and objects are harmed by gnawing.
