The positions were hard to fill as many of Utah's men were overseas fighting. Women began working, filling 25 percent of the jobs. As a result of Utah's and Geneva Steels contribution during the war, several Liberty Ships were named in honor of Utah including the USS Joseph Smith, USS Brigham Young, USS Provo, and the USS Peter Skene Ogden.
The Moab Man (also called "Malachite man") is a find of several human skeletons found after bulldozing in a mine whose rock dated to the Early Cretaceous period, about 140 million years ago. The original discovery of two individuals was made in 1971 by Lin Ottinger in the Keystone Azurite Mine near Moab , Utah , and has been used by ...
The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth.Dates in this article are consensus estimates based on scientific evidence, mainly fossils.
The linear view of human evolution began to be abandoned in the 1970s as different species of humans were discovered that made the linear concept increasingly unlikely. In the 21st century with the advent of molecular biology techniques and computerization, whole-genome sequencing of Neanderthal and human genome were performed, confirming ...
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]
The oldest human skeletal remains are the 40ky old Lake Mungo remains in New South Wales, but human ornaments discovered at Devil's Lair in Western Australia have been dated to 48 kya and artifacts at Madjedbebe in Northern Territory are dated to at least 50 kya, and to 62.1 ± 2.9 ka in one 2017 study.
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 discovery of human antiquity was a major achievement of science in the middle of the 19th century, and the foundation of scientific paleoanthropology.The antiquity of man, human antiquity, or in simpler language the age of the human race, are names given to the series of scientific debates it involved, which with modifications continue in the 21st century.
