Early humans were social and initially scavenged, before becoming active hunters. The need to communicate and hunt prey efficiently in a new, fluctuating environment (where the locations of resources need to be memorized and told) may have driven the expansion of the brain from 2 to 0.8 Ma. Evolution of dark skin at about 1.2 Ma. [39]
Over several decades, beginning in the late 19th century and continuing throughout the 20th, [481] in many countries the women's suffrage movement won women the right to vote, [482] and women began to enjoy greater access to education and to professions beyond domestic employment. [483] The first airplane, the Wright Flyer, flew on 17 December ...
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
The ancestors of the modern Khoi-San expanded to Southern Africa before 150,000 years ago, possibly as early as before 260,000 years ago, [note 5] so that by the beginning of the MIS 5 "megadrought", 130,000 years ago, there were two ancestral population clusters in Africa, bearers of mt-DNA haplogroup L0 in southern Africa, ancestral to the ...
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.
If an earlier civilization existed on Earth millions of years ago, we might have trouble finding evidence of it -- but that doesn't mean it didn't exist.
[89] [90] In sub-Saharan Africa, iron metallurgy was developed prior to any knowledge of bronze and possibly before iron's adoption in Eurasia [91] and despite Postclassic Mesoamerica developing and using bronze, [92] [93] [94] it did not have a significant bearing on its continued cultural evolution in the same way as western Eurasia.
Before Homo sapiens, Homo erectus had already spread throughout Africa and non-Arctic Eurasia by about one million years ago. The oldest known evidence for anatomically modern humans (as of 2017 [update] ) are fossils found at Jebel Irhoud, Morocco, dated about 360,000 years old.
