- Who Really Invented the Alphabet? (asor.org)
Who really invented the alphabet? Despite its vast influence, we are still uncertain about precisely where the world’s most influential communication system came from. One reason for this uncertainty is that debate about the alphabet’s origins has tended to focus on questions for which there is little clear evidence, such as the exact date of its invention and the personal identity, social status, and educational background of the inventor(s).
- Pangaea (Wikipedia)
Pangaea or Pangea (/pænˈdʒiː.ə/) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ago, at the end of the Triassic and beginning of the Jurassic. In contrast to the present Earth and its distribution of continental mass, Pangaea was centred on the equator and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists.
