Maria Branyas (born 4 March 1907) of Spain is the world's oldest living person whose age has been validated. [ 2] John Tinniswood (born 26 August 1912) of the United Kingdom is the world's oldest living man whose age has been validated. [ 2]
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period . It includes brief explanations of the various taxonomic ranks in ...
A 2009 poll by Harris Interactive found that 39 per cent of Americans agreed with the statement that "God created the universe, the earth, the sun, moon, stars, plants, animals, and the first two people within the past 10,000 years", yet only 18 per cent of the Americans polled agreed with the statement "The earth is less than 10,000 years old ...
Human evolution. The hominoids are descendants of a common ancestor. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes. [1]
Expansion of early modern humans from Africa. The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age.Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans, until the advent of the Neolithic ...
In 1862, the physicist William Thomson, 1st Baron Kelvin published calculations that fixed the age of Earth at between 20 million and 400 million years. [19] [20] He assumed that Earth had formed as a completely molten object, and determined the amount of time it would take for the near-surface temperature gradient to decrease to its present value.
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; graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia. 3800–3500 Ma
The earliest record of Homo is the 2.8 million-year-old specimen LD 350-1 from Ethiopia, [9] and the earliest named species is Homo habilis which evolved by 2.3 million years ago. [10] The most important difference between Homo habilis and Australopithecus was a 50% increase in brain size. [11]
