If dinosaurs were still alive today, it would have a significant impact on the world as we know it. Here are some possible scenarios based on the search results:
- Dinosaurs would be different: If the asteroid that caused the extinction of the dinosaurs had not hit Earth, dinosaurs would have continued to adapt and evolve, resulting in an entirely different mix of unknown dinosaurs. Even if we were able to clone long-dead dinos, it would be a challenging proposition, and most dinosaur species havent walked the Earth in about 65 million years, so the chances of finding DNA fragments that are robust enough to resurrect are slim.
- Humans and other mammals may not have evolved: With a preponderance of dinosaurs remaining on our planet, humans and many other mammals would not have had the chance to evolve into existence.
- Dinosaurs could cause serious damage: Dinosaurs could cause serious damage, especially if they were aggressive, due to their height and enormous weight.
- Feeding bonanza for carnivorous dinosaurs: Dead herbivores lying around would have presented a total feeding bonanza for carnivorous dinosaurs, such as Tyrannosaurus rex, and other at-least-partial scavengers.
- Reduced population of Earths inhabitants: If dinosaurs still existed, the population of the Earths inhabitants would be reduced. The dinosaurs would probably cut it in half, especially if humans could no longer survive with them. Not only would the number of humans be reduced, but the number of plants and animals would also be reduced. The number of animals, which is about 500 trillion, and the number of plant species, which is about 400,000, would decrease because they would become food for a large number of dinosaurs.
- Dinosaurs would be hunted: Smaller dinosaurs that infringed on crops or livestock would probably be hunted as "nuisance" animals, as wolves and dingoes are today. It would be really hard for large sauropods to survive alongside humans. Theyre so big and would require so much food.
In summary, if dinosaurs were still alive today, it would have a significant impact on the world, and it is unlikely that humans and other mammals would have evolved. Dinosaurs could cause serious damage, and their presence would result in a reduced population of Earths inhabitants. While it is interesting to speculate about what could have been, it is unlikely that we will ever need to worry about roaming herds of dinosaurs disrupting our rush-hour commutes.
