If Dinosaurs Had Not Become Extinct, How Could They Have Evolved?

Evolution of Dinosaurs

By Michelle ShiroPublished 3 years ago 5 min read

Some of the most fascinating creatures to have ever walked the earth are dinosaurs. It's a shame that we won't be able to see some of the coolest creatures come to life in Jurassic Park, but we are actually living with some creatures that are just as old as dinosaurs- like crocodiles and sharks. They haven't changed much since they appeared millions of years ago, but most dinosaurs didn't make it when the asteroids struck Earth.

The asteroid hit Earth and caused a lot of changes. Plants couldn't grow, and many herbivores became really hungry. This led to some dinosaurs changing their diets, and some evolved into new animals we know today. If the asteroid had hit Earth a different way, dinosaurs might have stayed on the planet. That would've affected evolution in ways we can't imagine- possibly helping human beings ascend to top of the food chain.

Think of a world where dinosaurs were still around today. We would have to compete if dinosaurs had evolved at the same rate as humans. Several species of humans, including Homo sapiens, or us, were alongside them overcome a humanoid dinosaur would be odd.

First off, they would appear different and more reptile than we do. Comparing a human and a dinosaur side by side would be interesting for several reasons, including the fact that dinosaurs had scales instead of human skin, sharper teeth, and probably fewer fingers on each hand. Dinosaurs also had sharp claws instead of scales for their nails. Dinosaurs had much better vision than mammals, so it's probable we'd see dinosaurs with enormous eyes. We don't know what they would sound like, although they might be guttural like crocodiles.

8 billion people now call the Earth home, a staggering number. With that said, if dinosaurs were the dominant organisms, the environment would be appropriate for them speaking of physical characteristics. We altered our surroundings to suit our demands. The creature may not look like the ideal reptile and its appearance might not be flattering, but if dinosaurs had evolved then these creatures could be your classmate or colleague at work. Scientists predicted what dinosaurs would look like if they had evolved into intelligent creatures that walked upright and had opposable thumbs. These Wiggly thumbs are important for evolution since they helped humans start using tools for defending themselves and hunting.

The largest land-dwelling dinosaur was the titanosaur, albeit the measurements are simply approximations based on fossilized bones. Not all dinosaurs were the same as fossils have shown; some were enormous while others resembled any present animal. The creature lived between 195 and 122 feet, according to estimates. There were dinosaurs all over the world in various time periods, climates, and landscapes, but only a few were known as Giants. However, while they excelled in body size, they lacked in brain size. Some of the most well-known dinosaurs, like the Allosaurus and Stegosaurus, had very small brains like me, meaning it would have been nearly impossible for them to properly comprehend their environment.

Nonetheless, the T-Rex, with its Allosaurus and greater brains, roamed the earth in the late Cretaceous Period. Contrary to popular belief, the T-Rex was actually quite slow and a human could have easily outrun it, so we know that these days they wouldn't belong in any competitive sports that involve running. The T-Rex's brain only weighed just under a pound while the human brain is nearly three pounds. It might have been cool to see a T-Rex evolve into an intelligent being with opposable thumbs on its tiny stick hand.

Although we are aware that dinosaurs may have been both herbivores and carnivores, the uprising. One thing remained constant: they had small brains. Other dinosaur species, such as long-legged and horned dinosaurs, were also present. Regardless, they were at the top of the food chain, even when tiny mammals made cameo appearances. However, when asteroids fell and wiped out the dinosaurs, mammals took over. The world today would be very different than it is today if dinosaurs and mammals had shared the top spot in the food chain and had evolved along similar lines. Dinosaurs would have had larger brains and would have challenged humans for the title of most intelligent animal.

Because of the strength and structure of our tongues, humans and parrots are able to communicate. If developed dinosaurs wished to speak like humans, their skulls would have been fashioned differently to accommodate such a tongue. We evolved the ability to stand up straight to detect predators, which was one survival strategy we had to master. But what would dinosaurs have to master if they were already the most dominant creatures? This is one of the reasons why humans have survived to where we are now.

Their evolutionary path would have been very different from that of humans and possibly even more advanced because some of the big brain dinosaurs had long legs, allowing them to run quickly, detect predators, and grab food that would otherwise be out of reach. Their brains may have evolved into something impressive, making them smarter than us and having quicker reflexes. Think of a dinosaur discovering gravity before Isaac Newton or producing plays and poems superior to William Shakespeare.

Imagine that dinosaurs had the creative ability to create some of the best works of art in history. Music and film would be inspired by dinosaur culture, and clothing would have an otherworldly appearance. We would coexist peacefully with dinosaurs, but we would definitely compete with them. Dinosaurs and humans would compete for their respective national teams in the World Cup, but clubs would be made up only of humans or dinosaurs. Some occupations would be controlled primarily by one species, and more physically demanding ones, such laborers and security guards, would be held by dinosaurs.

Dinosaurs would eventually rule the planet because they were physically more powerful than humans and had superior brains. Greater benefits than we have animals like whales, elephants, and other apes have bigger brains than humans, who are the smartest creatures on the planet, so why are we smarter than them? Humans, on the other hand, would need to figure out a way to keep up with Dinosaurs. Mammals had a different path of evolution than dinosaurs, never growing into enormous super beasts as dinosaurs did. Instead, their brains developed and grew big.

The answer is that we don't know the brain is the most complex organ we have, and because we know so little about it, we don't even know exactly why it's so complex or why it behaves in that way. Today's dinosaur descendants, like crows and parrots, have complex brains that enable them to communicate, use tools, and even count. Although size doesn't always equate to intelligence, in this case a parrot's brain is smaller than a cat's but it's far more complex and intelligent than that of any feline out there.

Some scientists argue that dinosaurs, in terms of evolution, the depictions in the movies aren't entirely accurate, and some little feathered dinosaurs might have followed the road taken by primates and evolved into a primate that lives in trees or into a different type of human.
