The organs of a body are a spatial division of labour, one created by different genes being turned on or off in different cells. The same process serves to give individual lives a division of labour ...
In flowering plants, the transition from cross-fertilization (outcrossing) to self-fertilization has evolved repeatedly across species. This shift is often accompanied by a well-known set of traits ...
