Unique laboratory experiment shows rapid evolutionary adaptation to ocean acidification and warming
The single most important calcifying algae of the world’s oceans is able to simultaneously adapt to rising water temperatures and ocean acidification through evolution. A unique long-term experiment with the species Emiliania huxleyi at GEOMAR Helmholtz Centre for Ocean Research Kiel shows that the evolutionary potential of the algae is much greater than previously thought. In their laboratory evolution experiment, the scientists have shown for the first time that evolutionary adaptations to multiple stress factors do not necessarily interfere with each other. Further work will reveal how evolution in ocean microbes may affect the function of the ocean in removing carbon dioxide to the deep sea and whether or not laboratory findings can be translated into the natural ocean environment.
