Climate change is already forcing lizards, insects and other species to evolve

Climate change threatens the survival of plants and animals worldwide as temperatures rise and habitats shift. Some species have managed to overcome this challenge by rapid evolutionary adaptation and other changes in behavior or physiology. Dark dragonflies become pale to reduce the amount of heat they absorb from the sun. Mustard plants are blooming earlier… Read More »

Lizards, fish and other species are evolving with climate change, but not fast enough
