The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence , mainly fossils .
This was the last major animal to be tamed as a source of milk, meat, power, and leather in the Old World. Lascaux aurochs, Stone Age [2] 3500 BC. Sumerian animal-drawn wheeled vehicles and plows were developed in Mesopotamia, the region called the "Fertile Crescent." Irrigation was probably done using animal power.
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.

The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
Monogamy in animals – Natural history of mating systems in which species pair bond to raise offspring; Reciprocal altruism – Form of behaviour between organisms; Reciprocity (evolution) – Mechanism favouring cooperative traits
Cambrian (541–485 Ma): The beginning of the Cambrian was marked by the Cambrian explosion, the sudden appearance of nearly all of the invertebrate animal phyla (molluscs, jellyfish, worms and arthropods, such as crustaceans) in great abundance. The first vertebrates appeared in the form of primitive fish, which were subsequently greatly ...
1830 — The Cuvier–Geoffroy debate in Paris on the determination of animal structure; 1831 — Mantell publishes an influential paper entitled "The Age of Reptiles" summarizing evidence of an extended period during which large reptiles had been the dominant animals. [14] 1832 — Mantell finds partial skeleton of the dinosaur Hylaeosaurus.
