Single vs multiple independent olive domestications: the jury is (still) out

The Concept of Multiple Allelism

Overview

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...
