BASED on observations at the University of Chicago, an African lungfish was found stepping lightly on its fins, the National Geographies reported on Tuesday. In this first time discovery of the behavior, the lungfish were able both to push off a solid surface and move along it using their pelvic fins.
The lungfish and other so-called lobe-finned fishes are believed to be close living relatives of the earliest known tetrapods - four-limbed animals with backbones. The finding provides new perspectives of how animals with backbones first hauled themselves from the sea to the land, according to scientists.
