Revisiting evolution theories: Dinosaurs were on way out before meteor hit


You thought dinosaurs became extinct after a meteor hit the Yucatan region of Mexico some 66 million years ago? Think again! A new study suggests the impact did indeed doom the animals, but that they were already on their way out due to a drop in temperatures. In this edition, we discuss this groundbreaking discovery with the co-author of the study, Fabien Condamine. 


We all know that some 66 million years ago, a six-mile-wide space rock hit the Yucatan region of Mexico, wiping dinosaurs off the face of the Earth. But would they have survived without it? New groundbreaking research suggests otherwise. Scientists at the Institute of Evolutionary Science in Montpellier have studied 1,600 fossils from 247 dinosaur species that lived during the late Cretaceous period. They found that some dinosaurs had already started to become extinct before the impact occurred. 

We talk to Fabien Condamine, the co-author of the study, and ask him how it's changing the way we view evolutionary theory and the need to constantly keep an open mind and revisit past beliefs. 

Our tech editor Peter O'Brien tells us how this applies not just to dinosaurs, but to our own species too. In fact, even Charles Darwin may not have had all the answers.

Plus, the source code for the World Wide Web has been auctioned off at Sotheby's in New York for $5.4 million in the form of an NFT. The programme paved the way for the internet as we know it today. 

And in Test 24, we take a look at how far underwater drones have come, from those that pilot themselves to one that anyone can pilot from home.
