The Enigma of Angiosperm Origins

by Norman Francis Hughes

Overview

The origins of angiosperms are still debated, despite many years of work by scientists from differing disciplines. The progress made toward resolving the problem is reviewed in this book. The author suggests that the only fruitful method of study is the total integrated use of the fossil record, particularly dispersed palynomorphs. This includes the use of electron microscopy and refined data handling to record the occurrence of microscopic fossils, rather than the extensive use of morphology and cladistics. The methods advocated in this book could result in a rethinking of the current classification of living plants, and it is hoped that the ideas presented will initiate discussion between both professionals and students of paleontology and plant science on the wider possibilities that may clarify the enigmatic origins of the dominant flowering plant groups.

Editorial Reviews

"The Enigma of Angiosperm Origins contains much of value and should be read by all those interested in angiosperm evolution. It is a thought provoking and controversial book in that it challenges conventional ideas and methods." Mary Dettmann, AASP Newsletter

"..a superb book..challenging and thought-provoking, without being intimidating...should make us all think about what we are doing and why." P.M. Rees, Geological Magazine

"...provides a useful overview on the Lower Cretaceous succession of monosulcate columellate-tectate pollen types." David Cantrill, Plant Science Bulletin
