MIT scientists have found that river erosion can promote biodiversity in areas with little tectonic activity. The study, centered on the Tennessee River Basin, revealed that erosion diversified populations of a fish species, potentially indicating a similar impact on other species.Pufferfish typically pump themselves up by taking 35 gulps or so in the course of 14 seconds. Each gulp draws in a big load of water thanks to some peculiar anatomic changes in their muscles and bones. Most fish, for example, have shoulder bones that anchor firmly to the back of their head, but in pufferfish the connection is hinged.

One of the biggest questions in evolution is when and how major groups of animals first evolved. The rise of tetrapods (all limbed vertebrates) from their fish relatives marks one of the most important evolutionary events in the history of life. This "fish-to-tetrapod" transition took place somewhere between the Middle and Late Devonian (~400-360 million years ago) and represents the onset ...LANTURN’s light can shine up from great depths.

Evans said flatfish evolution is particularly interesting because they began as typical, symmetrical fish. They started evolving their current shape, or morphology, about 65 million years ago, and within 3 million years, they'd largely finished. "We got all that novel colonization of morphospace in 3 million years' time," Evans said.

Shubin proceeds to support evolution by comparing characteristics of humans with that of phylogenetically older species. Embryology provides evidence for Shubin. All animals with skulls share something developmentally.
