Dr Alice Clement, an evolutionary biologist from Flinders University, joins the team to discuss the coelacanth—an ancient lineage of fish often referred to as "living fossils." Coelacanths have fleshy fins with a bone structure similar to human limbs, providing clues about vertebrate evolution. These rare fish live deep in the ocean, relying on immense pressure for survival.

Thought to be extinct for 66 million years, a coelacanth was rediscovered in 1938, which Clement likens to "a triceratops stumbling around in a forest." 

Clement recently discovered a new coelacanth species from 185 million years ago, with remarkably preserved fossils. Her research delves into how tectonic plate movement, or "proxy flux," affects the evolutionary rates of these fish and their extensive family of over 80 related species.
