Grim Reaper 6 Posted August 12 #1 Share Posted August 12 A rock that smashed violently into our planet some 66 million years ago changed the course of life on Earth. The chain reaction of changes across the globe marked the end of days for the giants that roamed. Non-avian dinosaurs disappeared into the fossil record – but their demise opened the way for other forms of life to rise and thrive.. Not long after the impact, the earliest ancestors of today's birds emerged. And now, scientists have found traces of the catastrophe in birds' genomes – dramatic changes wrought by the mass extinction event that allowed birds to diversify, becoming the wildly successful and varied class of animals that fills our world today.. https://www.sciencealert.com/traces-of-dinosaur-catastrophe-found-in-genes-of-todays-birds 1 Link to comment Share on other sites More sharing options...
Ell Posted August 12 #2 Share Posted August 12 That is impressive science. No doubt many chemical biologists will take notice of it and have it shape their own research and careers. 1 Link to comment Share on other sites More sharing options...
Oniomancer Posted August 13 #3 Share Posted August 13 (edited) Quote Berv and his colleagues used this software to analyze the differences in the genome between all the major groups of birds. This allowed them to identify shifts in the genome composition since the Cretaceous-Permian extinction. Uuuuuh....what? Permian was at least two extinctions before the dinos snuffed it. Did they mean to say the KT or are they tracking across multiple extinction events? They should've said earliest avian lineage ancestors as well.

I am also a little confused and I agree they should have included the earliest Avian lineage to this study. Link to comment Share on other sites More sharing options...
