"This is a fascinating book, challenging a number of preconceptions
and adding yet another mechanism for non-gradualist evolutionary
processes. . . . it is absorbing and authoritative, with many novel
thoughts for anyone interested in evolutionary processes."--The
Biologist
"An excellent addition to the Oxford Series in Ecology and
Evolution. . .readers are almost assured of an opportunity to
reconsider the latest published evidence in an engaging synthesis
of this topic."--Plant Science Bulletin
"Through a discussion of numerous intriguing studies, this book
makes multifaceted case for the importance of hybridization. It
also highlights the biases, misconceptions, and misinterpretations
that might lead to an underestimate of the evolutionary importance
of hybridization. . . .A convincing well-crafted testament to the
importance of hybridization in evolution. The reader will be
enlightened."--Science
"Comprehensive. . .thoroughly documented and illustrated with case
studies from many perspectives (including fossil, morphological,
and molecular genetic) and taxonomic groups." --Choice
"A book which will dispel many naive notions about hybridization
and is a clear and interesting read."--Trends in Ecology &
Evolution
"Intelligent, rewarding, and important. . . .Mike Arnold presents
the most extensive exposition on record for one side of an argument
that has deep roots in evolutionary biology. This argument revolves
around whether natural hybrids, and the variation releases by
hybridization, have a future. . . .A worthy and often original
addition to the literature on hybridization." --American Journal of
Botany
"Arnold has written a clearly structured and stimulating review of
current research on hybrid zones--especially valuable for its
summary of his work on the Louisiana Iris, which gives us probably
the best study of natural selection on field hybrids....Natural
Hybridization and Evolution is a substantial step in the right
direction..."--Genetical Research
"Arnold defines natural hybridization as a process in which
successful matings occur in nature between individuals from two or
more populations which are distinguishable on the basis of one or
more heritable characters. Hybrids are the result . . . Hybrid
zones are places where two or more populations of individuals that
are distinguishable on the basis of one or more heritable
characters overlap spatially and temporally, and cross to form
viable and at least
partially fertile offspring. Introgression is the movement of genes
or alleles from one population or species into another. . . .
Hybridization and introgression have been neglected in
evolutionary
biology since the 1940's. Arnold's book shows why we should not
ignore these phenomena . . . The major hypothesis of Arnold's book
is that natural hybridization can affect the evolutionary history
of the groups in which it occurs . . . This book generates much
thought and I recommend it highly."--Evolution
