snails

Pavement, smog, and lack of shade can increase temperatures in cities by up to 6ºF above the surrounding rural and suburban areas. We know the higher temperatures directly impact many species of animals, but is it possible that they could also affect the course of evolution and change the physiology of future generations? To answer this question, researchers from the Netherlands used a popular citizen science platform to gather data about the appearance of snails throughout a wide range of habitats.
