The Tibetan plateau has an average elevation of 4,000 meters (13,000 ft) above sea level and covers more than 2.5 million km 2; it is the highest and largest plateau in the world. In 1990, it was estimated that 4,594,188 Tibetans live on the plateau, with 53% living at an altitude over 3,500 meters (11,500 ft).
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).
People who are predisposed to develop high-altitude pulmonary edema may present a reduction in urine production before respiratory symptoms become apparent. [ 15 ] Humans have survived for two years at 5,950 m (19,520 ft, 475 millibars of atmospheric pressure), which is the highest recorded permanently tolerable altitude; the highest permanent ...
By his own account, Herbert Spencer described a concept similar to "survival of the fittest" in his 1852 "A Theory of Population". [9] He first used the phrase – after reading Charles Darwin's On the Origin of Species – in his Principles of Biology of 1864 [10] in which he drew parallels between his economic theories and Darwin's biological, evolutionary ones, writing, "This survival of ...
As they became bipedal, they began to live in groups that used weapons to fend off predators and hunt down prey. Running became a key aspect to the survival of the species. [ 4 ] Even with all this, it is the development of the brain that has guided the development of the muscle functions and structures in humans.

Adaptations in humans can be physiological, genetic, or cultural, which allow people to live in a wide variety of climates. There has been a great deal of research done on developmental adjustment, acclimatization, and cultural practices, but less research on genetic adaptations to colder and hotter temperatures.
