Research pushes back history of crop development 10,000 years

...s of a protracted model for the origins of domesticated crops used computer simulations that showed that over time a cultivated population will become monophyletic (settle into one stable species) at a rate proportional to its population size as compared various gene variations in the wild populations. They fou...

Monophyletic

In phylogenetics , a group is monophyletic ( Greek : of one stem ) if all organisms in that group are known to have developed from a common ancestral form, and all descendants of that form are included in the group. A taxonomic group that contain organisms but not their common ancestor is c...
