Last year, researchers in Germany reported similar adaptation to acid conditions in a single - celled alga. (newscientist.com)
Pespeni found that genes related to the movement of ions into and out of cells, lipid metabolism and growth showed significantly more changes in urchins reared under acid conditions. (newscientist.com)
This work shows that evolution can rapidly select the gene variants needed to adapt to more acid conditions, says Jennifer Sunday, an ecologist at Simon Fraser University in Burnaby, Canada. (newscientist.com)
