and its players in the Sept. 13 2013 online edition of Nature Communications Our results suggest that successful farming is a complex evolutionary adaptation
The answer is that the value of farming as a strategy depends on the circumstances. Farming by itself does not confer a selection advantage on the Dicty clones.
The reason is that farming is costly. Farmers save roughly half the bacteria available to them forgoing considerable food to save some for dispersal at a new site.
#Spread of farming and origin of lactase persistence in Neolithic Agescientists have brought to light the spread of dairy farming in Europe and the development of milk tolerance in adult humans.
