Before there were “continents”. Humans lived…


Before there were “continents”. Humans lived together on one land mass. And yes we were black. Watching this now on the history channel.


Pangaea (/pænˈdʒiːə/ pan-jee-ə;[1]) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, forming approximately 300 million years ago.[2] It began to break apart around 100 million years after it formed.[3] The single global ocean which surrounded Pangaea is accordingly named Panthalassa.


The name Pangaea is derived from Ancient Greek pan (πᾶν) meaning “entire”, and Gaia (Γαῖα) meaning “Mother Earth”.[4][5] The name was coined during a 1927 symposium discussing Alfred Wegener’s theory of continental drift.[citation needed] In his book The Origin of Continents and Oceans (Die Entstehung der Kontinente und Ozeane), first published in 1915, he postulated that prior to breaking up and drifting to their present locations, all the continents had at one time formed a single supercontinent which he called the “Urkontinent”. Originally, this theory was rejected because the predominant theory was that the Earth was cooling and shrinking, with mountains being the last regions to shrink.


Wegener’s theory that mountains were made by two land masses colliding with each other seemed unlikely because it was thought that nothing could move a landmass as large as a continent. [6] The name occurs in the 1920 and 1922 editions of Die Entstehung der Kontinente und Ozeane, but only once, when Wegener refers to the ancient supercontinent as “the Pangaea of the Carboniferous”.[7] by afro_vegan_ali http://ift.tt/1hrZ7oN
