Darwin's insight was grounded in sensory observation and humility. His first drawing of an evolutionary tree is distinguished by the profound marking near the top: I think. (Image in the public domain)

What Darwin Saw

Sir Charles Darwin realized that humanity is interwoven with nature, that all of life is in a state of constant flux. The empowerment of nature, made possible by Darwin’s integration of human life into the whole, and grounded in his lived experience and profound humility, is the foundation of modern ecology.

Ecological Succession: Forest Fires to the Ocean Floor

A new study reveals that new microbes supplant the active hydrothermal vent’s microbes after the site ceases to produce thermal energy. Though more research is necessary to fully understand the regeneration process in the dormant hydrothermal vents, the study provides an additional platform for ecologists to explore how ecosystems recover from natural unbalances and how species adapt to severe changes in temperature, acidity, and chemical composition.

Evolutionary Psychology of Climate Change

Why haven’t we rallied our collective power to mitigate climate change? Daniel Gilbert, a professor of psychology at Harvard University, argues that human brains evolved to respond to threats that have four features, ones that global warming lack.

Biomimicry: Learning From Nature’s Genius

Biomimicry is the science of studying and emulating nature’s solutions to the problems that human beings are trying to solve. Over the 3.8 billion years that life has existed on Earth, nature, through evolution, has come up with sustainable and robust solutions that work and that endure.

Penguin With a Pocket Square of Blue

Whether waddling amongst its young in snowy Antarctica or swimming in the northern shores of the Galápagos Islands, the familiar image of the penguin, with its black and white tuxedo is truly iconic. The Little Blue Penguin, however, reminds evolutionary biologists and wildlife enthusiasts that the world is rarely black and white.

The Red Queen and The Evolution of Sex

In the biological world, both within and between species, adaptive progress and success are relative. This notion of evolutionary relativism is known as the Red Queen Effect, a term derived from the Red Queen’s race in Through the Looking-Glass by Lewis Caroll.

Katherine Pollard: What Makes Us Human?

For the past six years Katherine Pollard has been working with the Chimpanzee Sequencing and Analysis Consortium comparing the genes of chimps and humans in order to more fully understand how the human genome has evolved. Using the software she created to study genomic data, Pollard was able to identify the areas of the human… read more
