Primary endosymbiosis is when descendants of a free-living species without endosymbionts evolves into the endosymbiont of another species.  Secondary endosymbiosis is where a free-living species with its own endosymbiont(s) is enveloped by a second host species.  After a period of gene transfer, the endosymbionts from the once free-living species become the endosymbionts of the second host, resulting in the transfer of endosymbiont genomes (mitochondria or chloroplasts) across phylogenetically-distinct host taxa.
