This is an age progression of the famous Turkana Boy, the Homo erectus fossil KNM-WT 15000 found by Kamoya Kimeu, Meave Leakey and Richard Leakey, It is believed to be between 1.5 and 1.6 million years old. However, the fossil definitely showed lumbar disc herniation, an injury implicated with his death. He also had a diseased mandible. (from wiki).  But what if Turkana, boy had aged normally?  I’m being MORE THAN “GENEROUS” here in assuming that he lived to a “ripe old age” of 65 which by present day standards is average, but in those times would be well over the top end of the lifespan which was 50 at most for Homo erectus. But indulge me. ;).
