What is evolution of life
Answers
The evolutionary history of life on Earth traces the processes by which living and fossil organisms evolved, from the earliest emergence of life to the present. Earth formed about 4.5 billion years (Ga) ago and evidence suggests life emerged prior to 3.7 Ga.[1][2][3] (Although there is some evidence of life as early as 4.1 to 4.28 Ga, it remains controversial due to the possible non-biological formation of the purported fossils.[1][4][5][6][7]) The similarities among all known present-day species indicate that they have diverged through the process of evolution from a common ancestor.[8] Approximately 1 trillion species currently live on Earth[9] of which only 1.75–1.8 million have been named[10][11] and 1.6 million documented in a central database.[12] These currently living species represent less than one percent of all species that have ever lived on earth.[13][14]
The earliest evidence of life comes from biogenic carbon signatures[2][3] and stromatolite fossils[15] discovered in 3.7 billion-year-old metasedimentary rocks from western Greenland. In 2015, possible "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia.[16][17] In March 2017, putative evidence of possibly the oldest forms of life on Earth was reported in the form of fossilized microorganisms discovered in hydrothermal vent precipitates in the Nuvvuagittuq Belt of Quebec, Canada, that may have lived as early as 4.28 billion years ago, not long after the oceans formed 4.4 billion years ago, and not long after the formation of the Earth 4.54 billion years ago
Explanation:
Evolution is a process that has given us Reality we have today. It painted life in size,shape, colors, population frequency and activities that we find in every part of the world. ...It is the inherited traits of a population of organisms through successive generations.
