Page "Microevolution" Paragraph 33

However, Leavitt was using the term to describe what we would now call developmental biology ; it was not until Russian Entomologist Yuri Filipchenko used the terms " macroevolution " and " microevolution " in 1927 in his German language work, " Variabilität und Variation ", that it attained its modern usage.

The term was later brought into the English-speaking world by Theodosius Dobzhansky in his book Genetics and the Origin of Species ( 1937 ).
