What If Dinosaurs Were Still Alive Today? - sciencenerds

Wouldn't it be cool to ascertain a real-life t-rex, if only that one fatal asteroid never hit the world, would dinosaurs still be alive today? would they have evolved? what humans have survived this long?  could we ever learn to coexist?




Here's what would happen if dinosaurs never went extinct until 66 million years ago dinosaurs of all shapes and sizes roamed the earth intelligent adaptable and sometimes weighing as much as two jet planes it'shard to believe that it only took one rock to wipe them all out of course this was no ordinary rock, the asteroid that took out the dinosaurs was nine miles wide and hit the earth with the destructive force of ten billion Hiroshima bombs, the radioactive shockwave obliterated everything for hundreds of miles in every direction and 75% of all species on earth went extinct if that asteroid had hit just a little earlier a little later or even a few miles off courses we would be living in a very different world today.

The rock that killed the dinosaurs struck the shallow waters of Mexico's Yucatan Peninsula had it landed a little farther off the coast in a deeper part of the ocean the water might have absorbed some of the blasts along with its devastating effects on the atmosphere but even if the asteroid missed the earth dinosaurs would have to survive many significant global events in order to make it to our time.
55 million years ago temperatures rose, the climate was 8 degrees hotter than it is today, rainforests crowded and vegetation flourished, herbivores would have adapted and thrived but they'd have started to look a little different, the plants of this period were less nutritious and easier to digest the meaning, dinosaurs would likely shrink in size since their new diet wouldn't have as much energy roughly 20 million years after that South America and Antarctica split creating a cooler and drier world climate during this period long-legged, fast-moving dinosaurs would have evolved to travel the huge landmasses across the globe.

Compared to mammals of this era, dinosaurs held significant advantages like having more teeth and better eyesight considering the dinosaurs were already so advanced scientists ponder whether mammals would have evolved in the least if dinosaurs hadn't gone extinct it's likely that the large animals we all know today would are preying the dinosaurs but remember humans evolved alongside woolly, mammoths and sabre-toothed cats while those species didn't survive the ice ages of two .6 million years ago given the evolutionary traits of some dinosaurs there is a chance they could have persisted but what about us could we handle freezing temperatures and large terrifyingly vicious predators and that they say running keeps the body warm but which may also cause you to taste better in an alternate universe if we did survive alongside these prehistoric beasts, it's possible we could see a true live t-rex on a protected reserve, not unlike Jurassic Park.

Human population growth and excessive hunting would have driven larger dinosaurs to near extinction today they would most certainly be an endangered species but those that shrank and adapted over millions of years could coexist peacefully among us, in fact, some actually do where do you think pigeons came from it's hard to believe that birds were once the size of biplanes but then again it's hard to believe that with a slight twist of fate we might have walked with Dinosaursor we might have become dinosaur chow and not have evolved at all but seeing is believing,

Science stands on facts, not faith so if you've got a passion for the incredible then keep Reading.
