"More than 3.5 billion years ago, small single-celled organisms acquired the capacity to photosynthesize" "Plants were restricted to the aquatic world until three billion years later, the first uncontroversial evidence for life is found 2,700,000,000 years ago.

Reef building sponges called stromatoporoids and corals suffered losses and stromatoporoids finally disappeared in the third extinction near the end of the Devonian.

starting about 2.500,000,000 years ago, sedimentary rocks affected by higher amounts of oxygen in the atmosphere, appear red, as though rusted. Fossils include earliest fish, but of types very different from modern ones. signs of the "tentative presence" of plants on land.

Mesoproterozoic from 1,600,000,000 to 1,000,000,000 years ago.

This showed life beginning with the Silurian system, which it described as "a marine deposit of vast extent containing abundance of marine organic remains.

Three strata of toadstone had been found, and the limestone under the third was as far as miners had reached.
