The 100 species with longest life-spans recorded and verified [1] This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include:
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described. [11]
Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. [9] [10] Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates.

The 100: A Ranking of the Most Influential Persons in History is a 1978 book by the American white nationalist author Michael H. Hart. Published by his father's publishing house, it was his first book and was reprinted in 1992 with revisions. It is a ranking of the 100 people who, according to Hart, most influenced human history.
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 ...
The concept of a struggle for existence goes back to antiquity: Heraclitus of Ephesus wrote of struggle being the father of everything, and Aristotle in his History of Animals observed that "There is enmity between such animals as dwell in the same localities or subsist on the same food. If the means of subsistence run short, creatures of like ...
[1] [2] [3] The earliest undisputed evidence of life on Earth dates from at least 3.5 billion years ago. [4] [5] [6] Evolution does not attempt to explain the origin of life (covered instead by abiogenesis), but it does explain how early lifeforms evolved into the complex ecosystem that we see today. [7]
