lived   in  Europe  for at  least   a   hundred thousand    years.  For the most    part,
this    was a   time    of  cold,   and for stretches,  it  was intensely   cold,   with    ice
sheets   covering    Scandinavia.    It  is  believed,   though  it’s    not     known   for
certain,    that,   to  protect themselves, the Neanderthals    built   shelters    and
fashioned   some    sort    of  clothing.   Then,   roughly thirty  thousand    years   ago,
the Neanderthals    vanished.
All sorts   of  theories    have    been    offered up  to  explain the vanishing.
Often    climate     change  is  invoked,    sometimes   in  the     form    of  general
instability leading up  to  what’s  referred    to  in  earth   science circles as  the
Last    Glacial Maximum,    and sometimes   in  the form    of  a   “volcanic   winter”
that’s  believed    to  have    been    caused  by  an  immense eruption    not far from
Ischia,  in  the     area    known   as  the     Phlegraean  Fields.     Disease     is  also
sometimes   blamed, and so, too,    is  simple  bad luck.   In  recent  decades,
though, it’s    become  increasingly    clear   that    the Neanderthal went    the way
of   the    Megatherium,     the     American    mastodon,   and     the     many    other
unfortunate megafauna.  In  other   words,  as  one researcher  put it  to  me,
“their  bad luck    was us.”
Modern  humans  arrived in  Europe  around  forty   thousand    years   ago,
and again   and again,  the archaeological  record  shows,  as  soon    as  they
