Discover strange facts about evolution: Tiktaalik's transition to land, Opabinia's five eyes, Charles Darwin's finches, and the natural selection events...

Explore how evolution shapes life on Earth through natural selection, sexual selection, convergent evolution, co-evolution, and adaptive radiation. Covers Darwin, living fossils, punctuated equilibrium, and evolution observed in real time.

Everything about Tiktaalik roseae: the 375-million-year-old fishapod that bridges fish and tetrapods, its Late Devonian habitat, anatomy, and the prediction-driven discovery on Ellesmere Island.

Everything about Hallucigenia sparsa: the bizarre 508-million-year-old Cambrian lobopodian from the Burgess Shale, reconstructed upside-down and backwards for forty years and now recognised as an ancient cousin of velvet worms.

Everything about Anomalocaris canadensis: the 515-million-year-old Cambrian apex predator from the Burgess Shale, misclassified as three separate animals for 99 years, and armed with 16,000-lens compound eyes and a radial-toothed circular mouth.

Everything about Opabinia regalis: the five-eyed, clawed-proboscis Cambrian oddity from the Burgess Shale whose 1975 reconstruction was so strange that delegates at the Paleontological Association meeting laughed out loud.
