What do you know/think about the genetically modified chickens that look like dinosaur headed?
I would like to argue more about this topic but I'm kind of lazy to write all I want to say.I don't think that's how bringing back dinosaurs would be, those primal genes that composed dinosaurs morphed and/or adapted to fulfill birds needs and also to be able to survive, at most, we are creating a new chicken species or a chicken dinosaur looking, but we are not resurrecting and extinct animal, it's kind of the same with the wolves they tried to revive. For the question "do we need dinosaurs back" I would say we definitely don't, since they become extinct for a reason, but some of them might be beneficial on today's world. Not long time ago, I saw an article which basically said that scientists are trying to bring back Mammoths to terraform arid places with their wastes (I that's not all the reasons but it's like the most important one). with that, I want to say that maybe bringing back big herbivores such as sauropods (long necked dinos such as brachiosaurus and amargasaurus) might be beneficial for terraforming arid land. One downside of that would be that it would definitively affect and change the whole food chain of said places.
