While Christopher Columbus was first to sight the Cayman Islands on May 10, 1503, Caymanian folklore holds that the island's first inhabitants were English soldiers involved in Oliver Cromwell's capture of Jamaica around 1658. The first recorded permanent inhabitant was Isaac Bodden, the grandson of one of these first settlers, born on Grand ...
Human history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers.They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of the Ice Age 12,000 years ago.
The earliest cave sites also appear in this stage. Unlike the earlier Acheulian industries in the Levant, flint is the primary material used for tool making, with the handaxe being the primary tool. The toolmakers developed different variants of handaxes different in shape and function, which replaced other tools such as cleavers.
The earliest geographical evidence of a human settlement was Jebel Irhoud, where early modern human remains of eight individuals date back to the Middle Paleolithic around 300,000 years ago. The oldest remains that have been found of constructed dwellings are remains of huts that were made of mud and branches around 17,000 BC at the Ohalo site ...
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 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.
About 2.1 billion years ago, a blob-like creature inched along on an early Earth. As the organism moved, it carved out tunnels, which may be the earliest evidence of a moving critter on the planet ...
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [1]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
