Large tides may have been a key factor in the evolution of bony fish and tetrapods

Pioneering research, published in Proceedings of the Royal Society A, into ancient tides during the Late Silurian—Devonian periods (420 million years ago—380 million years ago), suggests that large tides may have been a key environmental factor in the evolution of bony fish and early tetrapods, the first vertebrate land-dwellers.
