The Odyssey of Humanity on Nova

Two hour show this Sunday.  Lots of  good video.  Lots of inane commentary.  Lots of astounding conclusions presented without any of the evidence to support them.  For instance, the voice over says that Neanderthal man lacked projectile weapons (bow and arrow, throwing spears) that Homo Sapiens possessed.  The voice over fails to mention any evidence for this bold claim.  Were there counts of flint arrowheads from Neanderthal sites and homo sapiens sites?  How does one tell the difference between a flint spearhead from a thrusting spearhead from a throwing spear?  It's an important issue.  Hunting with a bow and arrow is one helova lot more effective than hunting with just a flint knife or a thrusting spear, merely because the hunter doesn't have to stalk as closely and risk spooking the game.  With a bow and arrow the hunter only has to get within 50 yards of his prey.  Which is a lot easier than stalking to within touching distance ( zero feet). 
   Then the voice over goes into the old Bering Land Bridge theory, the idea that man crossed over from Asia to America when the oceans were low and the Bering Straits became dry land.  This is a land lubber's idea.  In real life Alaskan Eskimos used to cross the modern day Bering Straits in skin boats (Umiaks) until the Soviets made life impossible for them after WWII.  The umiaks were covered with walrus hide, a quarter of an inch thick, tough as fiberglass.  Eskimo umiaks are strong enough to take the thrust of a 40 horsepower outboard motor. 
   They did show a umiak on video, but the voice over clearly doesn't under stand the difference between rowing and paddling.   If your boat is strong enough to take the thrust of the oarlocks,  rowing will take you much further and faster than paddling.  Indian birch bark canoes were paddled because the birch bark isn't strong enough for oarlocks. 
   Then we see a truly impressive Pacific ocean catamaran.  Two masts, cabins, big crew, very impressive vessel.  It's a modern replica.  No discussion of ancient catamarans.  Do they have pictures? rock carvings? a salvaged wreck?  or what?  I'd love to believe that Polynesians reached Hawaii in such a craft, but I'd like a little evidence.  Plus no details of the impressive modern replica, like length, displacement, speed, how high she could point up into the wind, what each of the twin hulls was made of.  Or what the sails might have been made of.  The replica's sails looked like modern Dacron to me.
   Nova  had a lot of dramatic flashy video, made a nice TV show, but the voice over displayed so much ignorance as to discredit the whole thing.
