There are two types – continuous and discontinuous. Natural selection explains how evolution occurs.

Permian extinction. Permian extinction - Carbon Cycle, Mass Extinction, Marine Life: The ratio between the stable isotopes of carbon (12C/13C) seems to indicate that significant changes in the carbon cycle took place starting about 500,000 to 1,000,000 years before the end of the Permian Period and crossing the boundary into the Induan Age (the ...The Permian extinction reminds him of Agatha Christie's Murder on the Orient Express, in which a corpse with 12 knife wounds is discovered on a train.

The Permian-Triassic extinction, sometimes called the "Great Dying," is the greatest mass extinction event in the fossil record. Occurring some 252 million years ago, it wiped out at least 80 percent of marine invertebrate species and approximately 70 percent of terrestrial vertebrate species living just before the event. More than half of ...Between 247 to 252 million years ago, Earth was reeling from a mass extinction called the end-Permian event. The die-off had wiped out most life on Earth, including most land plants.There are two extinction events in the Permian and the younger of the two, at the end of the period, was the largest in the history of life. It is relevant to the modern world because climate change on a massive scale may have played a role. When did it happen? There were two significant extinction events in the Permian Period. ….

The Permian-Triassic extinction event is also known as the Great Dying . It eradicated more than 95% of all species, including most of the vertebrates which had begun to evolve by this time.

Three of the four of the global composite magnetic polarity time scales shown were published before revisions to the estimated age of the end-Permian extinction event and the Permian-Triassic boundary (presently ca. 251.9 Ma; see text). This is also the case for the polarity record for the greater Germanic Basin, from Szurlies (2013). We used ...Extinction.
