The Linnaeus Centre for Marine Evolutionary Biology

Snails evolving into new species on the sea shore

Take a look at this pedagogic and educational youtube film about Littorina-snails and evolution, based on many years of research by Kerstin Johannesson and other Littorina enthusiasts.

The film is produced by Science Animated

The Linnaeus Centre for Marine Evolutionary Biology, CeMEB, brings together a broad expertise from different disciplines. We focus on evolutionary processes and mechanisms in marine species and populations. A main goal is to increase our understanding of how marine organisms adapt to new environmental conditions, for example changing sea water pH, temperature and salinity.

We started in July 2008, when we were selected for a ten year Linnaeus grant awarded by the Swedish Research Councils.
