OK, so evolution is a very slow process. 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. And you can see some of those tiny steps by helping out with the Evolution MegaLab.
Scientists and amateur naturalists have been studying the banded snail for many years and have found that the darker shell types tend to be more common under hedges and in other places where the background is brown, while in grass the banded snails tend to be lighter-coloured, yellow and more stripey. This is an example of adaptation.
We want your help to find out whether this pattern can still be found, because there has been a big decrease in the numbers of song thrushes in England over the last 30 years. If there are fewer song thrushes about, you would expect the different snails to be less faithful to their particular habitats than they used to be. Help us find out!
