Exaggerating the Evidence
nNational
Academy of Sciences booklet:
nDescribes Darwin’s finches as “a particularly
compelling example” of the origin of species.
nExplains how the Grants showed “that a single
year of drought on the islands can drive evolutionary changes
in the finches,” and that “if droughts occur about
once every 10 years on the islands, a new species of finch
might arise in only about 200 years.”
