Shapes of Time by Kenneth J Mcnamara
This text explores evolution down an avenue that links natural selection and genetics - the effect of changes to the rates and timing of growth and development. It delves into the living and fossil worlds to show how animals and plants have evolved when the carefully orchestrated pattern of embryological development is gently nudged off course - producing species that may have developed "beyond" their ancestors, or others that have developed less, looking more like over-grown juveniles. McNamara shows how this phenomenon - known as heterochrony - has affected many aspects of evolution, including the mechanism behind the selection of different breeds of animals, differences between sexes, and animal behaviour. Heterochrony accounts for the "Peter Pan syndrome," in which some species look like their ancestors' children. It explains what was really behind the evolution of flightless birds, how the dinosaurs got so big, how pterosaurs managed to produce a wing supported only by their fourth fingers, and what has driven the evolution of the animal closest to our hearts - the largest primate species with the biggest brain and longest childhood - Homo sapiens.
"Pleasantly and clearly written..[this book] has splendid diagrams that make their point brilliantly."--'New Scientist' "McNamara explains the complex facets of evolutionary biology [such as heterochrony and paedomorphosis] in a delightfully clear and entertaining matter...his engaging style of writing helps bring the reader into the fantastic world of evolution. By and large, 'Shapes of Time' is an excellent find to be savored like a good malt whiskey. I raise my glass to McNamara."--'Earth'
Kenneth J. McNamara is senior curator of invertebrate paleontology at the Western Australian Museum in Perth. He has investigated the role of heterochrony in evolution in a wide range of living and fossil animals in Europe, Australia, China, and Africa. He is co-author of 'Heterochrony: The Evolution of Ontogeny'.
