Photos suggest rhino horns have shrunk over past century, likely due to hunting

By scrutinising over a century’s worth of photos, University of Cambridge researchers have made the first ever measurements that show rhinoceros horns have gradually decreased in size over time. The research was done by Oscar Wilson, formerly a researcher in the University of Cambridge’s Department of Zoology, and Edgar Turner, of the Department of Zoology and UCCRI.
