Born in the year of Cuvier s death [1832], Gulick lived to see--and applaud--the introduction of Mendelism in biology. His career spanned and exemplified first the age of the naturalist explorers, then the period of ambitious and often contentious evolutionary theorizing that marked the decades around 1900.
