Science calls them the “oldest-ever proteins.” Their assumed age is “3.8 million years”, and researchers extracted them from ostrich egg shells found in Laetoli, Tanzania.
Scientists have estimated that collagen could last perhaps 1– 2 million years if kept frozen, otherwise it would not last even half a million years.
Laetoli lies just south of the Equator on a plain where temperatures would hardly ever fall below the freezing point, so it seems that dogma (millions-of-years) means more to these researchers than letting the evidence speak for itself.
