Does the inheritance of acquired characteristics play a significant
role in evolution? In this book, Eva Jablonka and Marion J. Lamb
attempt to answer that question with an original, provocative
exploration of the nature and origin of hereditary variations.
Starting with a historical account of Lamarck's ideas and the
reasons they have fallen in disrepute, the authors go on to
challenge the prevailing assumption that all heritable variation is
random and the result of variation in DNA base sequences. They also
detail recent breakthroughs in our understanding of the molecular
mechanisms underlying inheritance--including several pathways not
envisioned by classical population genetics--and argue that these
advances need to be more fully incorporated into mainstream
evolutionary theory. Throughout, the book offers a new look at the
evidence for and against the hereditability of environmentally
induced changes, and addresses timely questions about the
importance of non-Mendelian inheritance. A glossary and extensive
list of references round out the book. Urging a reconsideration of
the present DNA-centric view prevalent in the field, Epigentic
Inheritance and Evolution will make fascinating and important
reading for students and researchers in evolution, genetics,
ecology, molecular biology, developmental biology, and the history
and philosophy of science.
