Norman A. Johnson is an
evolutionary geneticist and science writer who serves as an Adjunct Professor at the
University of
Massachusetts. He received
a B.S. in Biology with high honors in research from the College of William and Mary (1987). His Ph.D. is
from the University of Rochester (1992) where he investigated
the genetic basis of sterility seen in male hybrids between closely related
species of Drosophila. In his
research, Dr. Johnson has taken several approaches to examine the genetics and
evolution of reproductive isolation between developing species, as well as the
evolution of development. He is also the author of Darwinian Detectives: Revealing the Natural History
of Genes and Genomes (Oxford University Press, 2007), a book written
for general audiences about how biologists infer evolutionary processes from
patterns seen in DNA sequences.
