Evolution
In Evolution, Strickberger has condensed a huge body of
scientific literature onto a manageable number of pages. He
explains patterns of evolution in plants, vertebrates and
invertebrates, and he does this in ways that will help teachers to
show their students what organic evolution is all about.
Evolution is divided into four major parts. In Part I,
called "The Historical Framework," Strickberger first recounts the
emergence and development of ideas about the origin of life and
about putative relationships among living things -- these ideas, he
says, are the "intellectual threads" that have led to our modern
concept of organic evolution. Then, in a chapter called "The
Darwinian Impact: Evolution and Religion," he confronts creationism,
describes the creationists' efforts to undermine the teaching of
biology, and provides an outstanding five-page article titled
"Responses to Creationist Arguments." Without rancor but with
considerable efficiency, Strickberger disposes of various assertions
that creationists put forth, including the claim that schools must
offset science with doses of biblical pseudoscience to achieve
"fairness." (Strickberger asks: Why stop there? Shouldn't the
schools also be required to teach astrology or phrenology or Mary
Baker Eddy's nonsensical ideas about disease?) Given the present
resurgence of creationist attacks on science education,
Strickberger's article is timely indeed and a real boon to teachers.
In Part II ("The Physical and Chemical Framework"), Part III ("The
Organic Framework") and Part IV ("The Mechanisms") Strickberger not
only explains evolutionary biology's major concepts but also
presents significant details that make those concepts
comprehensible. He shines as he provides well written discussions
of topics such as molecular clocks, neutral mutations, and
definitions of species -- and as we would expect, his
discussions of the genetic aspects of evolution are always adept,
concise and straightforward. (See, for example, his explication of
the homeobox gene complexes that govern segmentation in animals.)
His discussions of current, unresolved questions in evolutionary
biology will surely be useful to teachers who want to help their
students begin to think critically about science.
In his final chapter, "Culture and the Control of Human Evolution,"
Strickberger addresses such vexed topics as sociobiology, eugenics,
cloning, and genetic engineering. I find his material to be
reasoned, logical and suitably cautious. For example, he calls
attention to "the insufficiency of sociobiology when applied
uncritically to humans" (page 613), and he observes that prospective
applications of genetic engineering to humans will depend on the
development of "consensual ethical principles" to deal with genetic
manipulations and with the effects of genetic screening on privacy
and other values (page 620).
I think that Evolution falls short in two respects:
Strickberger has not given attention the evolution of quantitative
characters, and he has not told about the mathematical modeling of
evolutionary processes. Even so, Evolution is an excellent
book and will make a worthy addition to any high school's
professional library. It will be valuable not only to biology
teachers but also to teachers who give courses in history,
anthropology or sociology.

Laboratory of Molecular Systematics at the California Academy of
Sciences. He has written books about evolutionary genetics and the
genetics of speciation, and he is a coauthor of a college-level
general-biology text.

Will Prize This BookDavid L. Jameson
Monroe W. Strickberger's Evolution is an introductory college
text that many high-school teachers will prize as a reference book.
Strickberger is a veteran teacher and author whose other works
include a fine, comprehensive college textbook of genetics. His
thoughtful writing reflects his years of experience in teaching
bright students and in answering the questions that such students
ask.
