Scientists have discovered that there was a Magnetic Anomaly 41000 Years Ago. The event would have allowed more UV light to hit the planet's surface dramatically increasing human skin cancers.
Early Modern Humans had learned to sew warm and waterproof clothes while living in an ice age, and applied sewing skills to make sun protective clothing which they wore even when it was warm enough to go out naked. Early Modern Humans developed the custom of wearing clothes in this period.
They also discovered that red ocre clay could be used as a sun screen and applied it to their faces and other exposed skin. Living in caves for sun protection they used red ocre to invest art.
At the end of this 1000 year annomaly human populations exploded but the Neanderthals had become extict.
I suggest that the Early Modern Human ability to drill holes and then to sew were a more important part of our survival as a species.
When you wear swim briefs in the very stitching that holds them together you are demonstrating a skill that no other terrestrial animal has achieved!
Do they make speedos in a red ocre colour?
