    • www.evolutionmegalab.org This project is co-ordinating a survey of banded snails in the UK. It provides background information about the snails, video to show how to collect and identify the snails in you… See more

    Lesson Organisation

    Distribute the sheets and discuss the data presented. If following the Evolution Megalab protocol, collect some snails to study in one lesson and practice using the keys in the lab (with the video for support), then collec… See more

    Health & Safety and Technical Notes

    If surveying snails in the wild, carry out a full risk assessment for outdoor work, and observe appropriate hygiene precautions after handling snails. See more

    Ethical Issues

    Teachers should be careful to introduce the snails in a way that promotes a good ethical attitude towards them and not a simply instrumental one. Although they are simple organisms which may not 'suffer' in the same way … See more

    Procedure

    Investigation aThink about the data about shell colour collected in different months at a particular thrush’s anvil in a wood near Oxford. bStudy the graph of percentages of yellow snails and of snails with one or more band, base… See more

    Teaching Notes

    Thrushes smash snails on particular stones (called ‘anvils’) to break open the shell and free the soft body of the snail to eat. Collecting snail shells from a thrush’s anvil makes it possible to find out the proportion of the differ… See more

    Are banded snails an example of natural selection?The case of banded snails – Cepaea nemoralis and Cepaea hortensis – is a well-known example of natural selection. The adaptation of populations of species of this snail in different environmental conditions is used as a case study for evolution in action.

    Are land snails a good study system for addressing evolutionary problems?In species polymorphic for colour of the shell or soft body parts, information on genetic shifts in response to selective pressures is readily accessible. Studies reviewed in this paper exemplify the potential of land snails as study systems in addressing evolutionary problems.

    Do banded snails produce pale shells?In response to contrasting habitats, the frequency of EUB in banded snails is correlated with the frequency of genetically unbanded in the local population, indicating that multiple mechanisms of producing pale shells are important in adaptation to exposed habitats ( Johnson, 1980 ).
