Dinosaur they are living beings that have become extinct. Until now, the existence of these large reptiles could only be proven through the fossils found by researchers.
However, has it ever occurred to detikers what would have happened if dinosaurs hadn’t gone extinct? Can humans coexist with these large animals?
According to the site The conversation66 million years ago a 10-kilometer asteroid with a magnitude of 10 billion atomic bombs fell to Earth and destroyed the dinosaur species.
Due to the asteroid impact, there were various kinds of natural disasters such as earthquakes, tsunamis, up to the death of 90% of living things living on Earth. Scientists reveal that this event made humans experience revolution.
Mammalian species, including primates, experienced rapid development after the extinction of the dinosaurs.
So what would the Earth look like if dinosaurs didn’t go extinct?
The existence of dinosaurs becomes an obstacle to human evolution
Just imagine if the asteroid hadn’t hit the Earth, perhaps human evolution would never have happened.
Even though humans have minds and brains to think, speak, gather with many communities, the existence of dinosaurs will become an obstacle and prevent humans from dominating the Earth.
In the 1980s, a paleontologist named Dale Russell suggested that dinosaurs never went extinct and could have evolved to become intelligent tool users.
At that time, Russell called dinosaur which evolved similar to human like Dinosauroid.
Dinosauroid he believed he was able to walk upright because his body is human-like. Unfortunately, Russell’s speculation hasn’t been proven, considering most dinosaur species were large in size.
Dinosaurs body gets bigger
The dinosaur’s body grew bigger and bigger until it became a giant over time. For example, the dinosaur brontosaurus, which weighed 16-22 tons and was 21-23 meters long, evolved into a dinosaur weighing 30-50 tons and a body length of up to 30 meters.
Even so, the development of dinosaur body size was not accompanied by their brains. In the Cretaceous era or 80 million years ago, the brain of the tyrannosaurus weighed only 400 grams.
Meanwhile, the velociraptor’s brain weighed 15 grams. Compared to the human brain which weighs up to 1.3 kilograms, the dinosaur brain is much lighter.
Therefore, it is believed that the evolution of dinosaurs stopped due to the failure of the brain development of these large reptiles. However, scientists believe that dinosaurs lived with their herds.
Dinosaur brain development was different from mammals
This grouped life is testament to the complexity of dinosaurs. However, he can also stop due to his undeveloped brain.
On the other hand, scientists believe that dinosaur brains could continue to grow. However, there is little evidence to suggest dinosaur can evolve to become a genius like humans.
It’s different with mammals. Scientists say that mammalian evolution is inevitable, you can see this from the mammalian brain that continues to develop. Furthermore, the size of mammals has also evolved, but not to the point of becoming gigantic.
