Wonder

Did you know that humans are a type of lobe-finned fish!? Turns out our story begins 400 million years ago, when some very special fishies began making the move from sea to land, and we want to talk about it!! Dr Alice Clement heads up the Early Vertebrate Evolution Lab at Flinders University and has dedicated her career to understanding this history of life on Earth ... how the evolution of fish is the story of our own beginnings, too.Alice joins us in the studio for a conversation about her first fieldwork at the GoGo Formation in the Kimberley - one of the most extraordinary fossil sites in the world - to the moment she split open a limestone nodule and found a beautifully preserved fish inside (now on display at Melbourne Museum!). Alice brings the joy of discovery into every corner of this fun episode. One of our favourite moments was when she walked us through her favourite fossil - an Elpistostege - a predatory fishapod from a famous site in Quebec that Alice then helped image using high-powered X-rays. The x-rays revealed finger bones, hidden inside a fish's fin, that are anatomically equivalent to your own. How good!And we get the full story of Materpiscis, the pregnant fish with a fossilised embryo and umbilical cord still intact, whose species name is Attenborough (yes, the Sir David...). Alice is a wonderful guest, and this won't be the last time you hear her on Wonder.Thanks to the Geological Society of Australia for making this episode of Wonder possible!Find us at www.thegeoco.com.auInstagram & TikTok: @thegeocoSign up for GeoCo News on Substack: thegeoco.substack.comGeoCo comes to you from the traditional country of the Kaurna people of the Adelaide Plains, South Australia.

What does it take to discover a continent? Apparently four months in the Madagascan wilderness with no phone, some crunchy crickets to snack on, and a whole lot of time bouncing around on terrible roads in a beat-up Peugeot while thinking some very big thoughts.Professor Alan Collins from Adelaide University joins Holly and Anthony for a conversation that spans the formation of Gondwana, the naming of a long-lost ancient continent, and the importance of being beautifully, productively bored. This is a genuine delight as Alan shares with us his vintage field photos, stories of sleeping in remote villages, learning Malagasy on the fly, and finding dinosaur bones by the side of the road. What a geology-kinda-life!!And the science? Alan's research reconstructed continental collisions 600–700 million years ago when the oceans were pink and the continents a rusty-red... and a mountain range as mighty as the Himalaya that has long since vanished. Alan walks us through the plate reconstructions and explains why understanding all of this helps us understand why our planet turned out the way it did. Oh, and we find out where the name Azania actually came from. Spoiler: it involves a very well-thumbed Lonely Planet!Alan is a returning guest on Wonder. If you’ve heard him before, you’ll already know why we had to get him back. If you haven’t, this is a very good place to start.Make sure you're following Wonder wherever you get your podcasts - and chuck that notifications bell on!

The Rocky Mountains - lands of towering peaks glacier carved valleys, huge faults and unique geological heritage. In this episode of Wonder, we lace up our boots and head into the heart of the Rockies with the endlessly enthusiastic Nick Zentner, professor of geology at Central Washington University . Nick is a great storyteller, and together we unravel the colossal forces that built this iconic mountain range.Nick is a friend of our little podcast and we really appreciate his generosity of spirit in giving us his time.Make sure you're following Wonder wherever you get your podcasts - and chuck that notifications bell on!

We adored our time with writer, illustrator, educator, and 'not-geologist(!!!)', Vojta Hybl (aka @vojta.illustrates). Look, we don't have better words to summarise these ideas than those Vojta gifted us throughout this conversation.... so, please, go listen & enjoy 💗 What a joy.Here you can Vojta's gorgeous new book, Rocks, A Guide to the Stones Around Us and the Stories They Tell.

We start todays episode at the end of the world with Professor of Earth System Evolution, Ben Mills. Soon we're looking at his incredible grid cell model of the Earth and watching 537 million years of evolution play out in pixels: continents drifting, plants evolving, ice sheets growing, CO2 falling, climates flipping. Ben then really shows us something cool: a simulation wherein we build, or rather terraform, an exoplanet from scratch into a habitable planet. In realtime we seed a lifeless world with cyanobacteria... wait for oxygen... drop in algae, tinker with plants... And how did we go? Well, let's just say we're glad Gaia took care of this all on our planet, because left to us three, we're probably not making it out of the Snowball...If you haven't listened to part 1 yet, don't start this episode until you've done that!!!
