Timeline Of Life On Earth Diagram The story of evolution spans over 3 billion years and shows how microscopic single celled organisms transformed earth and gave rise to complex organisms like animals. by michael marshall. 14 july. [2] [3] estimates on the number of earth's current species range from 10 million to 14 million, [4] with about 1.2 million or 14% documented, the rest not yet described. [5] however, a 2016 report estimates an additional 1 trillion microbial species, with only 0.001% described. [6].

Evolution and the timeline of life on earth happened in stages over 4.6 billion years. from cyanobacteria to fungi. dinosaurs and chickens. whales and cows. monkeys to humans, the evolution of life is a story with surprising twists. earth has been home to over five billion different species of organisms. of all of those living life forms, an. The geologic time scale from 650 million years ago to the present, showing major evolutionary events. the evidence is overwhelming that all life on earth has evolved from common ancestors in an unbroken chain since its origin. darwin’s principle of evolution is summarized by the following facts. all life tends to increase: more organisms are. A timeline of the eons’s, era’s, & periods. the development of life over the last 3,700 million years of the earth's history is one of the great stories told by modern science. during most of this time living things left only traces to indicate their existence. then, about 544 million years ago, during what is referred to as the cambrian.

The diverse assortment of life includes bizarre looking animals like wiwaxia. 3.5 billion: unicellular life evolves. photosynthetic bacteria begin to release oxygen into the atmosphere. 3.8 billion: replicating molecules (the precursors of dna) form. 4.6 billion: the earth forms and is bombarded by meteorites and comets. Earth is about 4.5 billion years old. scientists think that by 4.3 billion years ago, earth may have developed conditions suitable to support life. the oldest known fossils, however, are only 3.7 billion years old. during that 600 million year window, life may have emerged repeatedly, only to be snuffed out by catastrophic collisions with.
