One h. erectus specimen from turkey dating to about 500,000 ybp demonstrates the antiquity of tuberculosis disease that is still prevalent today.
The earliest indication of tuberculosis in humans was found in mummies from Egypt and Peru that date to several thousand years ago, but this discovery in western Turkey closes a gap in time and space in human evolution.
Based on characteristics of the cranial suture closure, sinus formation, and the size of the brow ridges, the researchers determined that this specimen of Homo erectus belonged to a young boy.
Additionally, they discovered a number of tiny lesions carved into the skull's bone whose location and shape are typical of Leptomeningitis tuberculosa, a kind of tuberculosis that affects the meninges of the brain.
