This is a list of dates associated with the prehistoric peopling of the world (first known presence of Homo sapiens). The list is divided into four categories, Middle Paleolithic (before 50,000 years ago), Upper Paleolithic (50,000 to 12,500 years ago), Holocene (12,500 to 500 years ago) and Modern ( Age of Sail and modern exploration).
An important difference between Europe and other parts of the inhabited world was the northern latitude. Archaeological evidence suggests humans, whether Neanderthal or Cro-Magnon, reached sites in Arctic Russia by 40,000 years ago. [93] Cro-Magnon are considered the first anatomically modern humans in Europe.
Bones of the first gill arch became the upper and lower jaw, while those from the second arch became the hyomandibula, ceratohyal and basihyal; this closed two of the seven pairs of gills. The gap between the first and second arches just below the braincase (fused with upper jaw) created a pair of spiracles , which opened in the skin and led to ...
The Age of Discovery was the first period in which the Old World engaged in substantial cultural, material, and biological exchange with the New World. It began in the late 15th century, when Portugal and Castile sent the first exploratory voyages to the Americas, where Christopher Columbus first arrived in 1492.
Studies show that the pre-modern migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about 1.75 million years ago. Homo sapiens appeared to have occupied all of Africa about 150,000 years ago; some members of this species moved out of Africa 70,000 years ago (or, according to more recent studies, as early as 125,000 years ago into Asia, [1] [2 ...
The first debates about the nature of human evolution arose between Thomas Henry Huxley and Richard Owen. Huxley argued for human evolution from apes by illustrating many of the similarities and differences between humans and other apes, and did so particularly in his 1863 book Evidence as to Man's Place in Nature.
The first footprints were found in a dry lake bed in White Sands National Park in 2009. Scientists at the U.S. Geological Survey recently analyzed seeds stuck in the footprints to determine their ...
However, evidence of settlement in the wider Barada basin dating back to 9000 BC exists. [126] 6000 BC – 5000 BC: The earliest New World ceramics are created in the Amazon basin. [127] 5700 BC – 4500 BC: Vinča culture. 5500 BC: Copper smelting in evidence in Pločnik and Belovode. [128] [129]
