there isnt a plothole alive that cannot be retconned, perhaps the species transported through the portal wasnt modern man at all

rather a species evolving along similiar lines to the forerunners, or an entirely different species altogether

fossile records are nto that valuable

my theory is that the humans on earth prior to the war with the flood are descended from shipwreked forrunners, this would also explain the deformities if you take inbreeding into account.
