Every Monday for the next six weeks I’ll be posting about my recent trip to the Galápagos. After a week on a big boat, hopping from one imposing volcanic island to the next, I saw most of the odd creatures that Charles Darwin famously wrote about: century-old tortoises, finches with beaks of all sizes, swimming […]

There’s a song we all like to sing along to at our house. “Popcorn” by the Barenaked Ladies is uptempo, wistful, and propelled towards an explosive crescendo by an onomatopoetic beat. There’s much to love, in other words, but I always get tripped up a little by the first line of the lyric: Mama […]
You may have seen the extensive (and entertaining) press reaction days ago to a recent press release that cited Columbia University chemist Ronald Breslow taking liberties in his paper on the chirality of α-methyl amino acids. Breslow mentioned “advanced versions of dinosaurs,” who may live “elsewhere in the universe.” Gasp! The kicker? “We would be better off […]
This worm is born to travel. It begins life in human lymph, only to seep out of the lymphatic vessels into the grimy fluid that bathes our organs. From there, it drifts into the blood stream. During the day, it keeps to deep veins. Once darkness falls, it migrates up to the skinny veins just under […]

But the intelligent designer was missing in action, apparently, when it came time to assign our powers of excretion and elimination. The fish and birds […]

Patton and his colleagues at the Museum of Vertebrate Zoology were retracing the steps of renowned naturalist Joseph Grinnell, who surveyed California’s wildlife early in the last century — and obsessively documented his work in […]
In 2008, I published a book about the evolutionary origins and cultural development of warfare throughout human history. John Horgan, about as distinguished a science writer as one is likely to find, graciously invited me to share my thoughts on war’s deep past and possible futures on a web video show he hosted. It was […]
