Evolution Of Life On Earth Timeline From Earthwatchin Vrogue Co 539 ma – present. the phanerozoic eon (greek: period of well displayed life) marks the appearance in the fossil record of abundant, shell forming and or trace making organisms. it is subdivided into three eras, the paleozoic, mesozoic and cenozoic, with major mass extinctions at division points. 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.

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. 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. From 4.6 billion years ago when the earth was red hot, the timeline illustrates the evolution of the first life forms through to plants photosynthesising, bacterial evolution, marine life.

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. This interactive module explores key events in the record of life on earth, which stretches over three billion years. in this click & learn, students visit different times in earth’s history to learn what life was like at that time, based on scientific evidence. such evidence ranges from chemical signatures in rocks and ancient biological.
