Microbes evolve faster than ocean can disperse them

11 septiembre 2014

Scientists have created an advanced model aimed at exploring the role of neutral evolution in the biogeographic distribution of ocean microbes. Over the past sev­eral decades, ecol­o­gists have come to under­stand that both natural selec­tion and neu­tral evolution — that vari­a­tion within and between species is caused by genetic drift and random mutations — play a role in the bio­geo­graphic pat­terns of ocean microbes. New results flew in the face of the long held notion that microbes are infi­nitely mobile.
