Darwin’s theory of agency: back to the future in evolutionary science?

By Ben Bradley

Was Darwin a one-trick pony? The scientists who most laud him typically cite just one of his ideas: natural selection. Do any know that his theory of evolution—like his take on psychology—was drawn from a comprehensive analysis of organisms as agents? This fact has long been eclipsed by the “gene’s-eye view” of adaptation which gained a strangle-hold over biology during the twentieth century—and hence over sociobiology and today’s “evolutionary” psychology.

Dead zones: growing areas of aquatic hypoxia are threatening our oceans and rivers

By David Kirchman

A lake, sea, or coastal ocean turns into a dead zone when the supply of oxygen from the atmosphere and photosynthesis is overwhelmed by the use of oxygen during organic material degradation.

Darwin's Historical Sketch: An Examination of the 'Preface' to the Origin of Species

Ten things you didn’t know about Darwin

By Christina Fleischer

Charles Darwin’s birthday on 12 February is widely celebrated in the scientific community and has come to be known as “Darwin day.” In recognition of Darwin’s 212th birthday this year we have put together a list of ten interesting facts about the father of evolution.

Good news for honey bees from 150-year-old museum specimens

By Casey McGrath

The past several decades have been hard on Apis mellifera, the Western honey bee. Originally native to Europe, Africa, and the Middle East, Western honey bees have spread worldwide thanks to the nutritional and medicinal value of their honey, pollen, beeswax, and other hive products.

Unique adaptations allow owls to rule the night

By Casey McGrath

As the only birds with a nocturnal, predatory lifestyle, owls occupy a unique niche in the avian realm. Hunting prey in the dark comes with a number of challenges, and owls have evolved several features that leave them well-suited to this task.

When deterrence doesn’t work

By David P. Barash

No one likes to be threatened, and yet we threaten and are threatened all the time. From animal self-defence to how we raise our children, from religious teaching to gun ownership, capital punishment and nuclear deterrence, threat is an ever-present tool employed to influence an often-unpredictable external environment. But does it always work? And what are the consequences when it doesn’t?

Bring living waters back to our planet

By Rebecca Tharme, Julian Olden, Michael McClain, Angela Arthington, Mike Acreman, and Dave Tickner

Demanding the Indian government take action to clean and save the nation’s Mother River, the Ganga, activist and former civil engineer Professor G.D. Agarwal died from heart failure in 2018, after fasting for 111 days. Agarwal’s hunger strike remains symbolic of the mounting desperation many of us feel faced with the fragility of rivers, lakes, […]

How water conflicts hurt marginalized populations

By Naho Mirumachi

There are 286 international transboundary river basins that are shared by 151 countries. These basins are the source for water as well as livelihoods to 2.8 billion people. In many of these places the already vulnerable and marginalised are at great risk due to problems managing water. Sudden, sharp changes in these basins are not […]

Charles Darwin’s five-year journey [timeline]

By Andrea Standrowicz

Charles Darwin is most known for his journey to the Galapagos Islands, and for the work he published around the theory of evolution, The Origin of Species, as a result of that trip. And though his time in the Galapagos was vital to Darwin’s work, he also visited many other places, a small selection of […]

There’s no vaccine for the sea level rising

By William Rouse

We will get by the current pandemic. There will be a vaccine eventually. There will be other pandemics. Hopefully, we will be better organized next time. Waiting in the wings are the emerging impacts of climate change, the next big challenge. There will be no vaccine to stem sea level rise.

Why politics is so polarized, even though Americans agree on most key issues

By Carl Hunt, Lawrence Kuznar, and Stuart Kauffman

In 1971, Jerry B. Harvey created “The Abilene Paradox” to describe a pernicious failure: mismanagement of agreement. The late professor and management consultant posited that “the inability to cope with agreement, rather than the inability to cope with conflict, is the single most pressing issue of modern organizations.” “Getting on the bus to Abilene,” as […]

Six ways to reduce your environmental impact

By F Stuart Chapin

Over the last 50 years, human population has doubled, and global trade has increased ten-fold, drawing more deeply on Earth’s natural resources, warming the climate, and polluting the global environment. If current climate trends continue, a third of the global population will live in places warmer than the heart of the Sahara Desert 50 years […]

Envisioning a post-crisis world

By Carl W. Hunt and Stuart A. Kauffman

Their aim: Shape the Post […]

Earth Day at 50: conservation, spirituality, and climate change [podcast]

By Steven Filippi

Today is Earth Day. In fact, it is the 50th anniversary of the first Earth Day, when, at the behest of Wisconsin Senator Gaylord Nelson, an estimated 20 million people across the United States gathered to raise awareness for environmental protection and preservation.

How we can equip ourselves against climate change

By Ilan Kelman

Earth Day highlights the need for climate action, but what role does human-caused climate change play in creating disasters? Science paints a nuanced picture, instructing us to focus on reducing vulnerabilities to weather and climate, irrespective of how the environment is changing. Starting with the basics, a disaster is a situation requiring outside help for […]

The surprising scientific value of national bias

By Anne C. Rose

Emotions seem by their very nature to defy scientific analysis. Private and evanescent, and yet powerful and determining, feelings resist systematic observation and measurement. We are lucky to catch a glimpse in a facial expression or inflection of speech. The emotions of animals are all the more difficult. Without words to communicate what might be […]
