The fossil record of speciation as a result of geographical isolation, would follow the movement of Danakil. Within the Kolpochoerus lineage on Danakil, the earlier K. deheinzelini, is found in 4.3 to 4.6 Ma localities at the Aramis Member of Middle Awash[1], where the “Ardi” specimen of Ardipithecus ramidus was found as well, dated to 4.4 Ma. The younger K. afarensis (3.0–3.4 Ma) is found in Hadar[1], where the Lucy specimen of Australopithecus afarensis was found, dated to 3.2 Ma.
