Megabat evolved early in the lineage of chiropterans. Although echolocation was later lost in family Pteropodidae, bats in the genus "Rousettus" are capable of primitive echolocation through clicking their tongues, and some species have been shown to create clicks similar to those of echolocating bats using their wings. Both echolocation and flight are energetically expensive processes. The nature of the flight and echolocation mechanism of bats allows for creation of echolocation pulses with minimal energy use. Energetic coupling of these two processes is thought to have allowed for both energetically expensive processes to evolve in bats. The loss of echolocation may
Food Not Lawns Food Not Lawns Food Not Lawns is a de-centralized social movement focused on replacing urban lawns with food-producing organic gardens. The first group to use the name "Food Not Lawns" was founded in Eugene, Oregon in 1999 by Tobias Policha, Nick Routledge, and Heather Jo Flores. In 2006, Flores published the book "Food Not Lawns: How to Turn Your Yard into a Garden and Your Neighborhood into a Community." A self-described "avant-gardening collective", FNL's basic premise was to garner surplus resources, whether food, seeds, plants, tools, garden space, publications, or volunteer time, and channel them toward building better food security
