The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.

He suggested that dinosaurs, far from becoming extinct, had evolved into a wide variety of descendants in the form of birds. [1] [45] Ostrom's work led to a revolution in the classification of fossils and the understanding of dinosaur-bird lineages. [1] [2] Ostromia crassipes, previously known as the Haarlem Archaeopteryx
The largest dinosaurs, such as Diplodocus and Brachiosaurus evolve during this time, as do the carnosaurs; large, bipedal predatory dinosaurs such as Allosaurus. First specialized pterosaurs and sauropods. Ornithischians diversify. c. 199 Ma – First squamata evolve. Earliest lizards.
James Price Johnson (February 1, 1894 – November 17, 1955) was an American pianist and composer. A pioneer of stride piano, he was one of the most important pianists in the early era of recording, and like Jelly Roll Morton, one of the key figures in the evolution of ragtime into what was eventually called jazz.
