On the Feasibility of Cloning a Neandertal

Scientific American has just posted a very cool interactive feature online today that’s  entitled “Twelve Events that Will Change Everything.” One of these game-changing events,  suggests the magazine,  will be human cloning.

The section on human cloning is relatively short,  but it includes several points of interest.  As regular readers here know,  I take a strong interest in scientific research on Neandertals,  particularly on  developments that could lead to the cloning of this extinct hominin.   Read more…

The Lords of Beringia

I am continually gob-smacked by the obsessive public interest in Atlantis.  Why, oh why, does a mere mention of this fabled continent quicken the heartbeat of so many?  Google, as I just did, “continent of Atlantis,”  and you will turn up a whopping  1,020,000 hits.  And a depressing number are devoted to bizarre lunatic-fringe theories concerning the location of the sunken continent  (my current favorite puts Atlantis somewhere off the coast of the Indonesia).

By contrast,  try mentioning Beringia to your friends and kids.  How many of them have heard of it?   It’s a real, honest-to-goodness sunken land–a huge chunk of northern real estate that once connected Alaska to Siberia and that now lies at the bottom of the Bering Sea.  It drowned,  as many of you undoubtedly know,  when huge ice sheets melted at the end of the last Ice Age and topped up sea levels by some 330 feet.

Clothes Make the (Ancient) Man

“Good clothes,”  wrote Thomas Fuller in 1732  in his book of proverbs, Gnomologia,  “open all doors.” The British physician was  almost certainly thinking of the importance of a spiffy tailcoat and breeches and a dressy lace shirt when trying to make friends among the wealthy and titled in 18th century England. But Fuller’s proverb could apply to early hominins as well:  with the right clothing, our ancestors could survive winter cold and colonize increasingly hostile environments  in Eurasia.

All this of course begs a question,  or rather two.  Who were the first clothes horses?  And when did our mania for fashion begin?  Archaeologists have never had much clear evidence to go on,  for pieces of hide clothing or textiles tend to rot rapidly in the ground.    But new research presented last week at the American Association of Physical Anthropologists sheds new light on the matter,  by looking at an unlikely source of information: the human body louse.
