2025 Ep 28 Fish Evolution: Dr. Alexandre Siqueira
Dive into the deep past of our oceans with evolutionary biologist Dr. Axelandre Siqueira, whose work uncovers the origins and transformations of coral reef fishes over millions of years. From rare fossil records to cutting-edge genetic research, Alexandra explains how mass extinctions, shifting climates, and reef expansion shaped the dazzling diversity of species we see today.
In this wide-ranging conversation, we explore how fish evolved new feeding strategies, why coral reefs act as “fish factories,” and what ancient ecosystems can teach us about resilience in a warming world. Alexandre also shares his personal journey from inland Brazil to some of the most unique reefs on the planet, offering a fascinating perspective on science, discovery, and the wonder of marine life.
Whether you’re obsessed with fish ID or just curious about life beneath the waves, this episode reveals how evolution’s grand story is written in the scales and shapes of reef fishes.
