For some reason, animals keep evolving into things that look like crabs, independently, over and over again. What is it about the crab’s form that makes it so evolutionarily successful that non-crabs are apparently jealous of it?
Thanks to Franz Anthony for all of the ancient crab (and "crab") illustrations featured throughout this episode! franzanth.com/ And special thanks to Dr. Jo Wolfe, Dr. Javier Luque, and Dr. Katie Collins for assisting Franz with research for those illustrations.
And thank you to Dr. Rodney Feldmann for providing a photo of the Paralomis debodeorum fossil!

Fermis paradox solved. Civilizations develop in an an infinite number of planets, inventing technologies and ultimately space travel. But unbeknownst to them at the same time their doomsday clock is already ticking. The lucky ones kill themselves off with nuclear wars or climate change before their time runs out. But some make it to the singularity. Sending out messages to space, exploring their solar system. Looking more and more desperately for signs that they are not alone. Their electromagnetic output grows at an exponential rate, a beacon for everyone else to see. But it is too late. The messages cease, then one last explosion of brightness, one final deathcry. „The crabs are coming“ Then silence.
