Between 390 and 360 million years ago, the descendents of these organisms began to live in shallower waters, and eventually moved to land. As they did, they experienced natural selection that shaped many adaptations for a terrestrial way of life.

River basins are dynamic environments that are always changing and reorganizing under geologic forces. New research investigates how this shape shifting influences aquatic speciation and extinction. Read this at EOS The evolution of organisms and of their environments is inherently linked. Although the understanding that the gene pool is dynamic has shaped much of our

Discovery opens up new path in study of marine evolution and biodiversity. New UCLA research indicates that an evolutionary phenomenon never before observed among marine life could help explain why there is such immense biodiversity in the world's coral reefs and the ocean beyond. Two studies — one of reef-dwelling marine snails, the other.

This speed comes from 3 billion years of evolution and natural selection, allowing them to capture prey efficiently and achieve an image of dominance in the underwater ecosystem [3][4]. Though the human race places high value on speed for different reasons - convenience, efficiency, and productivity - scientists are looking to this.

The earliest fossil evidence for sharks or their ancestors are a few scales dating to 450 million years ago, during the Late Ordovician Period. Emma Bernard, a curator of fossil fish at the Museum, says, 'Shark-like scales from the Late Ordovician have been found, but no teeth. If these were from sharks it would suggest that the earliest forms.

The aquatic ape hypothesis ( AAH ), also referred to as aquatic ape theory ( AAT) or the waterside hypothesis of human evolution, postulates that the ancestors of modern humans took a divergent evolutionary pathway from the other great apes by becoming adapted to a more aquatic habitat. [1]
