The last common ancestor between humans and other apes possibly had a similar method of locomotion. 12-8 Ma The clade currently represented by humans and the genus Pan (chimpanzees and bonobos) splits from the ancestors of the gorillas between c. 12 to 8 Ma. [31] 8-6 Ma Sahelanthropus tchadensis
These migrations occurred during the most recent Ice Age, when various temperate regions of today were inhospitable. [37] Nevertheless, by the end of the Ice Age some 12,000 years ago, humans had colonized nearly all ice-free parts of the globe. [38] Human expansion coincided with both the Quaternary extinction event and the Neanderthal ...
Geologic Time – Period prior to humans. 4.6 billion to 3 million years ago. (See "prehistoric periods" for more detail into this.) ... and today is the span of ...
At long irregular intervals, Earth's biosphere suffers a catastrophic die-off, a mass extinction, [9] often comprising an accumulation of smaller extinction events over a relatively brief period. [10] The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes.
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
Time zones of the world. A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.

There are some traits that, although not strictly unique, do set humans apart from other animals. [296] Humans may be the only animals who have episodic memory and who can engage in "mental time travel". [297] Even compared with other social animals, humans have an unusually high degree of flexibility in their facial expressions. [298]
