Evolution Evolving - The Developmental Origins of Adaptation and Biodiversity

Overview

About this book

A new account of the central role developmental processes play in evolution.

A new scientific view of evolution is emerging—one that challenges and expands our understanding of how evolution works. Recent research demonstrates that organisms differ greatly in how effective they are at evolving. Whether and how each organism adapts and diversifies depends critically on the mechanistic details of how that organism operates—its development, physiology, and behavior. That is because the evolutionary process itself has evolved over time, and continues to evolve. The scientific understanding of evolution is evolving too, with groundbreaking new ways of explaining evolutionary change. In this book, a group of leading biologists draw on the latest findings in evolutionary genetics and evo-devo, as well as novel insights from studies of epigenetics, symbiosis, and inheritance, to examine the central role that developmental processes play in evolution.

Written in an accessible style, and illustrated with fascinating examples of natural history, the book presents recent scientific discoveries that expand evolutionary biology beyond the classical view of gene transmission guided by natural selection. Without undermining the central importance of natural selection and other Darwinian foundations, new developmental insights indicate that all organisms possess their own characteristic sets of evolutionary mechanisms. The authors argue that a consideration of developmental phenomena is needed for evolutionary biologists to generate better explanations for adaptation and biodiversity. This book provides a new vision of adaptive evolution.

Reviews

“Assembling a rich toolkit of insights from dung beetles and orcas to foxes and humans, Lala and colleagues have begun a major renovation of the comfy theoretical edifice constructed by the architects of twentieth-century evolutionary biology. Considering the impact of multiple inheritance systems (e.g., epigenetic, cultural, and microbial), plasticity, developmental biases, and niche construction on the core of evolutionary theory, they effectively raise the roof, knock down walls, and excavate the foundations, aiming to construct a more suitable theoretical structure for understanding the ‘endless forms most beautiful and wonderful’ of the twenty-first century. An engaging read, Evolution Evolving is an illuminating exploration for those curious about how all the new findings can fit into Darwin’s venerable house.”—Joe Henrich, author of The Secret of Our Success

“We can only come to fully understand and appreciate how novelty arises and how feedback and interactions—along with selection—shape the biological world if we expand our perspective, bringing together molecular, developmental, and evolutionary insights. With wonderful examples throughout, this book is a beautifully written and illustrated guide to help the reader better interpret and appreciate these interactions.”—Sarah Otto, University of British Columbia

“Evolution Evolving is a fascinating and original expansion of evolutionary theory, giving prominence to processes of embryonic development and the origins of novelty. The book is enlivened with many endearing examples and compelling stories, but the authors leave no doubt that their serious purpose is to demonstrate that cellular and developmental mechanisms deserve a central place in the thrilling story of the origin of species. A tour de force!”—Marc Kirschner, coauthor of The Plausibility of Life: Resolving Darwin's Dilemma

“This book is a signpost in the ongoing journey of evolutionary thinking, even though not everyone will agree with the direction it is pointing. Only a frank and open discussion will eventually lead to a renewed ‘synthesis’ of evolutionary knowledge. For that this book will be an important point of reference.”—Günter P. Wagner, author of Homology, Genes, and Evolutionary Innovation

“An eloquent, example-laden, accessible narrative setting the stage and offering the story of a truly contemporary evolutionary theory. The book represents a myriad of theoretical frames and approaches united by the focus on developmental biology, with robust examples, well-argued theory, and a sincere, even compassionate, invitation to think together.”—Agustín Fuentes, Princeton University

A thoughtful, interesting, and informative overview of major themes and research areas in contemporary evolutionary biology. Although some of the perspectives outlined in this book are controversial (and I often found myself disagreeing with the authors!), I would recommend this book to anyone seeking a better understanding of the ideas at the core of the 'Extended Evolutionary Synthesis'.”—Russell Bonduriansky, University of New South Wales

Series: Elements in Metaphysics

Teleology

Summary

Teleology is about functions, ends, and goals in nature. This Element offers a philosophical examination of these phenomena and aims to reinstate teleology as a core part of the metaphysics of science. It starts with a critical analysis of three theories of function and argues that functions ultimately depend on goals. A metaphysical investigation of goal-directedness is then undertaken. After arguing against reductive approaches to goal-directedness, the Element develops a new theory which grounds many cases of goal-directedness in the metaphysics of powers. According to this theory, teleological properties are genuine, irreducible features of the world.

The Unfinished Reconstructed Nature of the Last Universal Common Ancestor

Review Open access

Published: 18 July 2024

Luis Delaye



Abstract

The ultimate consequence of Darwin’s theory of common descent implies that all life on earth descends ultimately from a common ancestor. Biochemistry and molecular biology now provide sufficient evidence of shared ancestry of all extant life forms. However, the nature of the Last Universal Common Ancestor (LUCA) has been a topic of much debate over the years. This review offers a historical perspective on different attempts to infer LUCA’s nature, exploring the debate surrounding its complexity. We further examine how different methodologies identify sets of ancient protein that exhibit only partial overlap. For example, different bioinformatic approaches have identified distinct protein subunits from the ATP synthetase identified as potentially inherited from LUCA. Additionally, we discuss how detailed molecular evolutionary analysis of reverse gyrase has modified previous inferences about an hyperthermophilic LUCA based mainly on automatic bioinformatic pipelines. We conclude by emphasizing the importance of developing a database dedicated to studying genes and proteins traceable back to LUCA and earlier stages of cellular evolution. Such a database would house the most ancient genes on earth.

Explanatory gaps in evolutionary theory

Open access

Published: 01 September 2024

Volume 39, article number 22, (2024)

Abstract

Proponents of the extended evolutionary synthesis have argued that there are explanatory gaps in evolutionary biology that cannot be bridged by standard evolutionary theory. In this paper, we consider what sort of explanatory gaps they are referring to. We outline three possibilities: data-based gaps, implementation-based gaps, and framework-based gaps. We then examine the purported evolutionary gaps and attempt to classify them using this taxonomy. From there we reconsider the significance of the gaps and what they imply for the proposed need for an extended evolutionary synthesis.

SALVE A DATA!

Lançamento do livro: "A Evolução é Fato"

Nos dias 19 e 20 de setembro, às 9h, a Academia Brasileira de Ciências lançará sua mais nova publicação “A Evolução é Fato”, obra que busca reforçar uma mensagem clara: a evolução é um fato científico e a pedra basal na qual se sustentam as ciências biológicas, sua existência é provada todos os dias na biodiversidade do planeta e também nas biotecnologias, como as vacinas e antibióticos em constante atualização para combater novas cepas de patógenos.

O livro é fruto de um trabalho conjunto de membros da ABC coordenados pelo Acadêmico Carlos Frederico Martins Menck. O lançamento ocorrerá em duas datas, no dia 19 de setembro, na sede da Financiadora de Estudos e Projetos (Finep), e no dia 20, no Fórum de Ciência e Cultura da UFRJ. Ambos são localizados no bairro do Flamengo, no Rio de Janeiro.

A ABC não compactua com criacionismo ou desenho inteligente. A ciência baseia-se em evidências e observações empíricas testáveis, é dependente de métodos científicos, da compilação de dados. A ciência busca explicar fenômenos pela avaliação, comprovação e experimentação, e está sempre em desenvolvimento. A evolução é o princípio fundamental da ciência moderna.
