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

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