The Evolutionary Morphology Laboratory led by Shigeru Kuratani at the RIKEN Cluster for Pioneering Research (CPR) in Japan, along with collaborators, has found evidence that the mysterious ancient fish-like vertebrate Palaeospondylus was likely one of the earliest ancestors of four-limbed animals, including humans.
