The theory of evolution is regarded as a triumph of disinterested scientific reason. Yet, on the 150th anniversary of "On the Origin of Species," new research reveals that Darwin was driven to the idea of common descent by a great moral cause

Mutual Aid: A Factor of Evolution
Mutual Aid: A Factor of Evolution is a 1902 collection of anthropological essays by Russian naturalist and anarchist philosopher Peter Kropotkin. The essays, initially published in the English periodical The Nineteenth Century between 1890 and 1896, explore the role of mutually beneficial cooperation and reciprocity in the animal kingdom and human societies both past and present. It is an argument against theories of social Darwinism that emphasize competition and survival of the fittest, and against the romantic depictions by writers such as Jean-Jacques Rousseau, who thought that cooperation was motivated by universal love. Instead, Kropotkin argues that mutual aid has pragmatic advantages for the survival of human and animal communities and, along with the conscience, has been promoted through natural selection.
Evolution
Evolution is the change in the heritable characteristics of biological populations over successive generations. It occurs when evolutionary processes such as genetic drift and natural selection act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation.

Sapiens [Tenth Anniversary Edition]: A Brief History of Humankind
New York Times Readers’ Pick: Top 100 Books of the 21st CenturyThe tenth anniversary edition of the internationally bestselling phenomenon that cemented Yuval Noah Harari as one of the most prominent historians of our time—featuring a new afterword from the author.One hundred thousand years ago, at least six human species inhabited the earth. Today there is just one. Us. Homo sapiens. How did our species succeed in the battle for dominance? Why did our foraging ancestors come together to create cities and kingdoms? How did we come to believe in gods, nations, and human rights; to trust money, books, and laws; and to be enslaved by bureaucracy, timetables, and consumerism? And what will our world be like in the millennia to come?In Sapiens, Professor Yuval Noah Harari spans the whole of human history, from the very first humans to walk the earth to the radical—and sometimes devastating—breakthroughs of the Cognitive, Agricultural, and Scientific Revolutions. Drawing on insights from biology, anthropology, paleontology, and economics, and incorporating full-color illustrations throughout the text, he explores how the currents of history have shaped our human societies, the animals and plants around us, and even our personalities. Can we ever free our behavior from the legacy of our ancestors? And what, if anything, can we do to influence the course of the centuries to come?Bold, wide-ranging, and provocative, Sapiens integrates history and science to challenge everything we thought we knew about being human: our thoughts, our actions, our heritage...and our future.
Without a theory of intelligence
The history of science — and of progress — is a series of benefits that are direct results of new tools.

Mutual Aid: A Factor of Evolution
From Mutual Aid In the animal world we have seen that the vast majority of species live in societies, and that they find in association the best arms for the struggle for life: understood, of course, in its wide Darwinian sense — not as a struggle for the sheer means of existence, but as a … Continued

This idea that intelligence is solely a function of what you've observed since birth and not also a function of the 500 million years of evolution that preceded your birth is surprisingly sticky despite being demonstrably untrue. https://t.co/m2z5cN8Byb— Jon Barron (@jon_barron) January 28, 2026

Speculations on the Future of the Scientific Method
The following essay was published 20 years ago (January, 2006) on my blog The Technium. I edited the intro here, but the speculations are basically unchanged.

Maximum power in evolution, ecology and economics
Ludwig Boltzmann suggested that natural selection was fundamentally a struggle among organisms for available energy. Alfred Lotka argued that organisms that capture and use more energy than their competition will have a selective advantage in the evolutionary process, i.e. the Darwinian notion of evolution was based on a fundamental, generalized energy principle. He extended this general principle from the energetics of a single organism or species to the energetics of entire energy pathways through ecosystems. Howard Odum and Richard Pinkerton, building on Lotka, extended this concept to ‘The maximum power principle’ and applied it to many biological and physical systems including human economies. We examine this history and how these ideas relate to concepts from other disciplines including philosophy. But there has been considerable confusion in understanding and applying these concepts which we attempt to resolve while providing various examples from routine life and discussing some unresolved issues. This article is part of the theme issue ‘Thermodynamics 2.0: Bridging the natural and social sciences (Part 2)’.
