Today, billions of people around the world start their day with caffeine. But how and why did the ability to produce this molecule independently evolve in multiple, distantly-related lineages of flowering plants, again and again? youtu.be/PzshAqowsyI

Although they both produce caffeine, ☕coffee and 🍊citrus plants last shared a common ancestor over 100 million years ago! Why would so many different plants independently evolve to produce caffeine? ow.ly/1wpN50K972c

Humans are part of the only group of mammals that do not produce the chemical marker "Alpha-Gal." In fact, we actively produce antibodies against it. Why did our lineage ditch an otherwise universal feature of mammal biology? This is what we'll investigate in this week's episode!

In today's new Eons episode, we're filtering through the evidence around the evolution of the "big mustache inside a whale's mouth" a.k.a. baleen. Let's just say, sometimes the history of life on earth is weirder than we expect! 🐋 youtu.be/ITEMAKa4-lc

A fossilized leaf shows evidence of ants' "death grip" and is the oldest known evidence of zombie ants -- which still exist today! 🧟‍♂️🐜How and why are these fungal spores able to infect and create zombified ants? Hear the whole story in today's video! ow.ly/JLfF50Kqt9j

The discovery of a new domain of life was pretty surprising, even if archaea looks like bacteria. But in recent years it’s been archaea's connection to us that's turned out to be full of surprises. We may be connected to a group called Asgard Archaea. ow.ly/hLvT50LkQlN

Paleontologists have found more than 2 dozen of the oldest known seahorse fossils in Slovenia. But what were seahorses doing there? These animals are better suited to clinging to a stalk of coral or a blade of seagrass, not open-ocean swimming... Find out in tomorrow's new video!

🎉Another episode of our podcast is available on YouTube! This episode is a mystery in the most classic sense of the word. It’s a whodunit detective story that spans more than a century -- the saga of the Piltdown Man Hoax. ow.ly/Hy2750LRKOi

Shanidar Cave in modern day Kurdistan is the final resting place of a Neanderthal known as “Shanidar IV," nicknamed the “flower burial.” But did Neanderthals actually bury their dead? Tomorrow's new video will explore this possibility and what it might tell us about Neanderthals.

~30 million years ago, Nautilus fossils began to vanish from the fossil record of marine environments across the world. Whatever caused this population contraction seems to still be active today. Who is the nautiloids' unexpected predator? Find out now! youtu.be/3vQ55ToQeWI

Confession: We spend so much time talking about animals here on Eons that sometimes we forget how fascinating plant evolution can be! 🌿 Dig into today's new video to unearth the surprising story of how some plants survived the K-Pg extinction. youtu.be/4XmFUWdgKWk

What would humans be like if some of the steps on our evolutionary journey had gone a little differently? l8r.it/4XDD
