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 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 ...

Earth is the only place in the universe known to harbor life, where it exists in myriad environments.

[2] [3] [4] Since its emergence, life has persisted in several geological environments.
The Life Nature Library is a series of 25 hardbound books published by Time-Life between 1961 and 1965, with revisions to 1968. It has been translated from English into eight languages and sold in 90 countries. [ 1 ]
All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA. A new study suggests that this organism likely lived on Earth only 400 million years after its formation.
In early agriculture at this time, the planting stick is used, but it is replaced by a primitive plow in subsequent centuries. [107] Around this time, a round stone tower, now preserved to about 8.5 metres (28 ft) high and 8.5 metres (28 ft) in diameter is built in Jericho .
The book is then divided into three parts by era, first of which is The Rise of Life, which covers the Precambrian and the Paleozoic Era. The second part, The Age of Reptiles, covers the Mesozoic Era. The third and final part, The Age of Beasts, covers the Cenozoic Era. The book concludes with a timescale of life on earth, tree of life diagrams ...
