For this week’s discussion post i have chosen to discuss an article in the science daily magazine on the topic of why humans are practically brow less. IN 1921, IN Zambia, a Swiss miner named Tom Zwiglaar, came across a preserved skull, while mining in a zinc mine. This skull was sent to London’s Natural History Museum, to be studied by a paleontologist, Arthur Smith Woodward. This skull has been famously named as Kabwe 1 or Broken Hill Skull. It is believed to be 300,000 to 125, 000 years old.
