Life on Earth started about three-and-a-half billion years ago. It's the tiny changes accumulating over a long, long time that got us here. Citizen scientists can see some of those tiny steps by joining the Evolution MegaLab.

The main focus of this research is the banded snails (Cepaea nemoralis and Cepaea hortensis), which can be found in almost any part of the U.K. where snails are generally present. Citizen scientists will seek out these snails and keep records of the locations where they are found using maps and satellite pictures on the Evolution MegaLab Web site.
