The Permian period lasted from 299 to 251 million years ago* and was the last period of the Paleozoic Era.The distinction between the Paleozoic and the Mesozoic is made at the end of the Permian in recognition of the largest mass extinction recorded in the history of life on Earth.

It’s difficult to say when life first arose because the first lifeforms were tiny single-celled animals that didn’t fossilize. As a result, there’s no direct evidence of life in the fossil record.

This timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth.In biology, evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organization, from kingdoms to.

The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution. Among them were the chordates, to which vertebrates (animals with backbones) such as humans belong.

This fact determined the end of the Carboniferous, a period of the Paleozoic Era that had started 60 million years before. The results, published in the last number of Science, indicate that these.

The Cambrian spans from 541 million years to 485 million years and is the first period of the Paleozoic era of the Phanerozoic. The Cambrian marked a boom in evolution in an event known as the Cambrian explosion in which the largest number of creatures evolved in any single period of the history of the Earth. Creatures like algae evolved, but the most ubiquitous of that period were the armored.

The Paleozoic (also spelt "Palaeozoic") era lasted from about 540 to 250 million years ago, and is divided into six periods The 320-odd million years of the Paleozoic era saw many important events, including the development of most invertebrate groups, life’s conquest of land, the evolution of fish, reptiles, insects, and vascular plants, the formation of the supercontinent of Pangea, and no.
