(Phys.org) —A team of researchers from the Sorbonne Universités have found evidence of an ancient sloth returning to the sea to survive. In their paper published in Proceedings of the Royal Society B: Biological Sciences, the team describes how they performed CT scans on a number of fossilized bones and in so doing discovered a change in density—evidence of a move to the sea.
