Yes elmo, I think you’ve got stuck in question mode. I’m sure you knew the answer to this one. We’ve talked a lot about the origins of life and evolution. At what point you call something ‘life’ is difficult but is probably related to the arrival of DNA/RNA and the first cells. Dinosaurs had to evolve from the cellular level. I guess they were around about 230 million years agow whereas life probs originated over 3 billion years ago…
