The Boskop Man is an anatomically modern human fossil of the Middle Stone Age (Late Pleistocene) discovered in 1913 in South Africa. [1] The fossil was at first described as Homo capensis and considered a separate human species by Broom (1918), [2] but by the 1970s this "Boskopoid" type was widely recognized as representative of the modern Khoisan populations.
An elephant's brain weighs just over 5 kg (11 lb), a bottlenose dolphin's 1.5 to 1.7 kg (3.3 to 3.7 lb), whereas a human brain is around 1.3 to 1.5 kg (2.9 to 3.3 lb). Brain size tends to vary according to body size. The relationship is not proportional, though: the brain-to-body mass ratio varies. The largest ratio found is in the shrew. [56]
Date apprehended. 1870. John Edward Howard Rulloff (also known as Ruloff, Rulofson, or Rulloffson, as well as several aliases; 1819/1820 – May 18, 1871) was a Canadian-born American medical doctor, lawyer, schoolmaster, photographer, inventor, carpet designer, phrenologist, and philologist, in addition to a career criminal and serial killer.
Homo naledi. Homo naledi is an extinct species of archaic human discovered in 2013 in the Rising Star Cave system, Gauteng province, South Africa (See Cradle of Humankind), dating to the Middle Pleistocene 335,000–236,000 years ago. The initial discovery comprises 1,550 specimens of bone, representing 737 different skeletal elements, and at ...
For comparison, modern human men and women in the year 1900 averaged 163 cm (5 ft 4 in) and 152.7 cm (5.01 ft), respectively. [42] The femoral head , the best proxy for estimating body mass, is missing, but using the shaft, OH 80 weighed about 50 kg (110 lb) assuming humanlike proportions, and 61.7 kg (136 lb) using the proportions of a non ...
The evolutionary history of the human brain shows primarily a gradually bigger brain relative to body size during the evolutionary path from early primates to hominins and finally to Homo sapiens. This trend that has led to the present day human brain size indicates that there has been a 2-3 factor increase in size over the past 3 million years ...
The first Australopithecus specimen, the type specimen, was discovered in 1924 in a lime quarry by workers at Taung, South Africa. The specimen was studied by the Australian anatomist Raymond Dart, who was then working at the University of the Witwatersrand in Johannesburg. The fossil skull was from a three-year-old bipedal primate (nicknamed ...
The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system.
