Focusing on the origins of body plans, this book explores the broader evolution of animal development. It delves into the biological and evolutionary processes that shape how animals develop, providing insights into the intricate relationships between structure and function across various species.
Why do the best-known examples of evolutionary change involve the alteration of one kind of animal into another very similar one, like the evolution of a bigger beak in a bird? Wouldn't it be much more interesting to understand how beaks originated? Most people would agree, but until recently we didn't know much about such origins. That is now changing, with the growth of the interdisciplinary field evo-devo, which deals with the relationship between how embryos develop in the short term and how they (and the adults they grow into) evolve in the long term. One of the key questions is: can the origins of structures such as beaks, eyes, and shells be explained within a Darwinian framework? The answer seems to be yes, but only by expanding that framework. This book discusses the required expansion, and the current state of play regarding our understanding of evolutionary and developmental origins.
This book is for everyone with an interest in whether there is extraterrestrial life. Recent discoveries of planets beyond the solar system (more than 4000 of them) suggest that the question is not 'whether?' but 'where?'. This book enables general readers to understand current endeavours to answer this question and the related one of 'what kind?'
Exploring the philosophical implications of evolution, this work emphasizes the significance of complex organisms emerging from simpler forms, a perspective often overlooked in both scientific and popular discussions. The book critiques the tendency to focus on horizontal diversification among species, such as finches and moths, while neglecting the vertical progression of life forms. By addressing the historical context that has led to this omission, it aims to reshape the understanding of evolutionary biology and its broader implications.
Covering all the main animal groups, from jellyfish to mammals, this book unravels the story of animal evolution.
This groundbreaking book introduces Evolutionary Developmental Biology in an accessible format for undergraduates and general readers. It explores the relationship between evolution and development, highlighting key concepts and discoveries in the field. The text presents complex ideas in a clear manner, making it suitable for those new to the subject, while offering insights that engage a broader audience interested in the mechanisms of biological change and diversity.

All humans share three origins: the beginning of our individual lives, the appearance of life on Earth, and the formation of our planetary home. Wallace Arthur combines embryological, evolutionary, and cosmological perspectives to tell the story of life on Earth and its potential to exist elsewhere in the universe.
This book is aimed at anyone interested in the existence and nature of extraterrestrial life, including general readers and students of astrobiology, astronomy, planetary science, and evolutionary biology. It focuses on two key issues: where is alien life to be found, and what is it like?
