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 ...
H. erectus is the first known species to develop control of fire, by about 1.5 Ma. H. erectus later migrates throughout Eurasia, reaching Southeast Asia by 0.7 Ma. It is described in a number of subspecies. [38] Early humans were social and initially scavenged, before becoming active hunters.
The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes. Researchers have identified five other major extinction events in Earth's history, with estimated losses below: [ 11 ]
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 known musical instruments besides the human voice are bone flutes from the Swabian Jura in Germany, dated around 40,000 years old. [26] Paleolithic humans lived as hunter-gatherers and were generally nomadic. [27] The migration of anatomically modern humans out of Africa took place in multiple waves beginning 194,000–177,000 ...
The earliest known remains of Cro-Magnon-like humans are radiocarbon dated to 43,000–46,000 BP, found in Bulgaria, Italy, and Great Britain. [33] [34] Europe: Bulgaria: 46-44: Bacho Kiro cave: A tooth and six bone fragments are the earliest modern human remains yet found in Europe. [35] Europe: Italy: 45–44: Grotta del Cavallo, Apulia
Pierre-Simon Laplace, one of the originators of the nebular hypothesis. Ideas concerning the origin and fate of the world date from the earliest known writings; however, for almost all of that time, there was no attempt to link such theories to the existence of a "Solar System", simply because it was not generally thought that the Solar System, in the sense we now understand it, existed.
At least two-thirds of Mars' surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; [4] Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there.
