In the case of hemochromatosis, it is believed that a single individual in Europe, 60 to 70 generations ago, was the sole origin of most of the hemochromatosis seen in the world today.
Our analyses support an ancient (late Paleoproterozoic) origin of photosynthetic eukaryotes with the primary endosymbiosis that gave rise to the first alga having occurred after the split of the Plantae (i.e., red, green, and glaucophyte algae plus land plants) from the opisthokonts sometime before 1,558 MYA.ur results also show that the earliest possible date for the putative single secondary endosymbiosis in the Chromista (fig. 1, node 3), in which a non-photosynthetic protist captured a red algal plastid is 1,274 MYA, after the split of the Cyanidiales from the other red algae 1,370 MYA (fig. 1, node 2).
