divergence estimates based on gene identity in
the presence of migration (p. 142).The fact that
migration (even if it is small) increases gene
identity (and hence decreases the divergence
time estimate based on it)was known from Nei
and Feldman (1972)and Chakraborty and Nei
(1974)even before Slatkin, Maruyama, and Li’s
papers (cited by Jorde) and Nei and
Roychoudhury (1974) made adjustments
accounting for recent migration. The blunt
characterization of such estimates as an
“exercise in futility” (p. 142) is, thus, overly
harsh. Similar comments apply to his migration-models section as well. Nevertheless, it is a
good review and should stimulate new readers
of the subject.
The subject of genetic epidemiology, which
constitutes the major thrust of the volume,
and where the connection to anthropological
genetics is loosest, is presented in six chapters
(Chapters 9 through 14).Though the history of
this subject is reviewed at great length in these
writings, it is unfortunate to see that no single
article cites Neel and Schull(l954)or Neel et al.
(1965),
who coined the term and identified all of
the aspects of genetic epidemiology that characterize the current directions of research in
this subject. These six chapters, in aggregate,
set forth the methodological approaches of the
proponents of segregation analysis (R.C.
Elston, C. Cannings, E.A. Thompson, etc.)
path analysis (N.E. Morton, D.C. Rao, T.
Reich, etc.), and the use of specific sampling
designs (e.g., Half-sib design reviewed by C.C.
Li). The 165 pages of reading leaves one with
the idea that these methods are bestowed with
the “power of resolution” in distinguishing
between the degrees of biological and cultural
determination for traits that run in families
and refer to the “greatly oversimplified
models” of others. But are these methodologies
without caveat? Lewontin (1974), Karlin
(1979),
as well as others, have raised objections
to the different aspects of these various analytic strategies, some of which are obviously
known to these authors. We expected some
words of caution if such criticisms are indeed
valid, or at least counterarguments proving
their inadequacies. A critical reader will find
this to be a serious drawback.
Overall, the book is certainly an up-to-date
description of the subject and should be useful
for students and teachers alike. I t is well produced, and should tolerate the heavy use it
warrants. A few typographic errors (none very
damaging however) occasionally marred the,
otherwise, nice print-scripts (e.g. an extra 6
factor in the denominator of the intermediate
step of equation 2.3 on page 330; and on Figure
5 of p. 332 the vertical dotted lines are to be
labeled as $,,
and $AA instead of 4,,,
and 4,).
