Jakarta, CNBC Indonesia – Dinosaurs died out 66 million years ago when an asteroid hit the Earth with the force of 10 billion atomic bombs.
This event changed the course of evolution. The sky darkens, plants stop photosynthesizing, and food chains collapse.
However, this cataclysmic event made human evolution possible. The surviving mammals thrived, including the tiny proto-primates that would evolve into what we are today.
Imagine the asteroid missed and the dinosaurs survived. Dinosaur scientists, discovering relativity or discussing a hypothetical world that mammals could have conquered the Earth.
In the 1980s, paleontologist Dale Russell proposed a thought experiment in which carnivorous dinosaurs evolved to become intelligent tool users like humans. Scientific alarmWednesday (21/12/2022).
This “dinosauroid” had a large brain, opposable thumb, and walked upright, as discussed in the Canadian Journal of Earth Sciences.
The common thread connecting dinosaurs is that they were sauropods. Dove possessed the anatomy of a sauropod, consisting of a lung, hollow bones with a high strength-to-weight ratio, metabolism, which unlocked their evolutionary potential. It allowed them to grow in a way that land animals never could before.
Similarly, carnivorous dinosaurs repeatedly developed large predators. Over the course of 100 million years, megalosaurids, allosaurids, carcharodontosaurids, neovenatorids, and finally tyrannosaurs evolved into gigantic apex predators.
Dinosaurs had large bodies, but their brain sizes were not that large. Dinosaurs showed a weak trend of increasing brain size over time. Jurassic dinosaurs such as allosaurus, stegosaurus and brachiosaurus had small brains.
By the end of the Cretaceous, 80 million years later, tyrannosaurs and ducks had evolved larger brains. But despite its size, the T. rex brain still weighed just 400 grams. The Velociraptor brain weighed 15 grams. The average human brain weighs 1.3 kilograms.
Dinosaurs occasionally entered a new niche. Small herbivores are becoming more common and birds are becoming more diverse.
It seems that dinosaurs had an increasingly complex social life. They started living in herds and developed horns for fighting and showing off. But most dinosaurs seem to have repeated it, developing giant herbivores and small-brained carnivores.
They may have evolved slightly larger brains, but there is little evidence that they evolved genes. Nor is it likely that mammals will replace them. Dinosaurs monopolized their environment until the end of their lives when an asteroid hit.
