tried   to  identify    ethnicities or  ethnic  groupings   for the purpose of  study,
soliciting  the help    of  physical    anthropology.   Under   the influence   of  Charles
Darwin’s    pioneering  work    on  evolution,  the 19th    century saw a   wealth  of  racial
theories    about   the human   species,    many    of  which   built   on, or  degenerated into,
unscientific    racist  doctrines.
The colonialist expansion   had led European    scholars    to  discover    the ‘wisdom of
the Indians’,   the ‘Chinese    scientific  genius’,    and made    them    salute  ex  oriente lux
(‘out   of  the east,   light   comes’).    However,    their   appreciation    of  other   ‘high’
civilizations   did little  to  undermine   the general assumption  of  the white   man’s
superiority,    which   legitimized the continuation    of  slavery,    domination, and
exploitation,   in  spite   of  the Enlightenment’s ideals  of  freedom and equality,
which   were    all-inclusive   only    in  name.
The catastrophes    of  the 20th    century,    notably the extermination   of  Jews    in  the
Shoah,  discredited the most    blatant forms   of  racism, but racialist   notions proved
to  be  hard    to  eradicate   completely  from    the investigation   of  humanity’s  ethnic
multitude.  It  was only    in  the 1980s,  when    major   progress    in  genetic research
gave    rise    to  the monogenesis theory  of  a   common  African ancestry    of  humanity,
that    skin    colour  and other   physical    traits  were    recognized  as  adaptive    features    of
discordant  groups  rather  than    distinguishing  human   races.  Ever    since,  human
biologists  have    mostly  discarded   race    as  a   meaningful  category.
Ethnographers,  however,    sustained   their   project of  separating  groups  and
subgroups,  replacing   race    by  culture,    understood  as  the ensemble    of  artefacts,
customs,    beliefs,    and institutions    accepted    by  a   group.  Small   groups  living  in
remote  areas   held    the promise of  presenting  primeval    ways    of  life    uncorrupted
by  modernity   and were    therefore,  for some    time,   the ethnographers’  preferred
object  of  investigation.  They    were    always  marginal    and are more    so  today.
Already in  the 1930s,  French  cultural    anthropologist  Claude  Lévi-Strauss
entitled    his study   of  the secluded    Nambikwara  in  the wilds   of  Brazil  Tristes
Tropiques   (Sad    Tropics),   knowing that    their   way of  life    was doomed. Stagnation
means   death.
Modern  civilization    has left    few areas   untouched.  As  global  capitalism  spreads,
commodities,    technologies,   and populations circulate   around  the globe   with
increasing  intensity,  pushing many    indigenous  peoples to  the brink   of  extinction.
This    does    not mean    that    humanity    fuses   into    one big homogeneity or  that    a
