Life Sciences

What is this thing called life? Biologists are life's detectives, discovering how life works and what makes animals, plants and microbes "alive." Organisms don't remain the same forever. Without change, life on Earth would stagnate. Species are in a constant dance with their environment. When an environment changes, the species that live within must change too, evolving to better adapt in order to survive. The end result is the diversity of life we see around us.
