Why We Only Have Ten Toes (It's a Long Story)

Today, all mammals from humans to bats have five fingers or fewer. Yes, even whales, whose finger bones are hidden in their fins. Birds have four or fewer and amphibians get the best of both worlds, often having four digits on their “hands” and five on their “feet.” But no species of vertebrates have more than five digits, let alone eight!

How Horses Went From Food To Friends

Do our modern horses descend from just one domesticated population, or did it happen many times, in many places?

EP3  How the Rise of Social Insects Shrunk These Dinosaurs
Jan. 27,2022
How the Rise of Social Insects Shrunk These Dinosaurs

We often think of dinosaurs as either preying on other dinos or mammals, or as plant-eaters -- but in ecosystems today, those aren’t the only two options. So why would we expect dinosaurs to have only been carnivores or herbivores, with the occasional omnivore thrown in the mix?

EP2  Primates vs Snakes (An Evolutionary Arms Race)
Jan. 19,2022
Primates vs Snakes (An Evolutionary Arms Race)

The Snake Detection Hypothesis proposes that the ability to quickly spot and avoid snakes is deeply embedded in primates, including us - an evolutionary consequence of the danger snakes have posed to us over millions of years.

Jan. 11,2022
How our deadliest parasite turned to the dark side

Around 10,000 years ago, somewhere in Africa, a microscopic parasite made a huge leap. With a little help from a mosquito, it left its animal host - probably a gorilla - and found its way to a new host: us.
