Welcome … to Cute-E!
During our Spook-E series, we speculate on the evolution of monsters from myth and popular media, but we leave out fiction’s more adorable creatures. In Cute-E, we choose cuddlier critters and discuss how they – or something like them – could evolve here on Earth, pulling inspiration from real-world species across our planet’s history. This year’s theme is Monsters of Nintendo.
This episode, we pluck precious partners from the soil. What could be the evolutionary background of tiny and colorful workers that blend the features of plants and animals? Our creatures to create this time: Pikmin.

Generally speaking, it’s not a good idea to mess with ants. But several lineages of animals have evolved to be ant-eating specialists. This episode, we discuss anteaters, the suite of adaptations that allow them to focus on ant-eating, and the variety of other species that have evolved similar adaptations for the same purpose. We explore the evolutionary history of ant-eating mammals and even dinosaurs through the fossil record and genetic evidence.
In the news: butt-drags, ancient leeches, Neanderthal tracks, and spider genomes.

The faces of vertebrate animals are often soft and full of teeth, but there is a common alternative. Birds, turtles, and many more groups have developed toothless snouts covered in a tough sheath. This episode, we’ll explore the defining features of beaks and their various functions. And we’ll take a tour through animal life past and present to investigate the reasons behind the repeated evolution of beaks among dinosaurs and beyond.
In the news: Life on Mars, ancient sharks, mammoth microbes, and ant-eaters.

Dodos are probably the single most famous case of recent human-induced extinction. First documented in the late 1500s and extinct within a century, dodos have become a global reminder of the devastating potential of human activity. This episode, we review the brief history of human interactions with dodos, and we explore what recent research and fossil evidence has taught us about these birds and their closest relatives.
In the news: Cretaceous crocs, extra-spiky dinosaurs, turtles of the sea, and cave fish evolution.
