As a result of this genetic modification, Man lost most of his saurian appearance and nature, his shiny, luminous skin, and scaly hide. He acquired mammalian characteristics - a soft flexible skin, body hair, the need to sweat, and the ability to produce live young. He no longer ran around naked. He now had to wear clothing for comfort and protection. For all purposes, Man was now a Homo sapiens. Modern man or Cro-Magnon Man had arrived upon the scene.
