What happened if dinosaurs did not disappear? Scientists have the picture

Merdeka.com – About 66 million years ago, the Earth, ruled by various species of dinosaurs, had to undergo major changes. The change occurred when an asteroid 10 kilometers wide with a force of 10 billion atomic bombs hit the Earth.

The blow caused earthquake earth, tsunami, in the death of 90 percent of living creatures that live on Earth. Although it brought great destruction, scientists revealed that it was this event that allowed humans to evolve.

Mammal species including primates may have thrived after the death of various dinosaurs.

But imagine if the dinosaur-killing asteroid never hit Earth. They believe that the asteroid strike that spurred human evolution will never happen. People with brains to think, with tools, languages, and diverse communities also believe that they do not dominate the Earth.

So, what would happen to life on Earth if the dinosaurs never went extinct and humans never existed?

Paleontologist Dale Russell in the 1980s once revealed that dinosaurs that never died may have evolved into intelligent tool users. At that time Russell called dinosaurs that evolved similar to humans as ‘Dinosauroids’.

Russell believes that dinosaurs themselves could walk upright because of their human-like bodies. But Russell’s speculation must be proven considering the many species of large-bodied dinosaurs that have ever been found. This was quoted in the Conversation, Monday (28/11).

Imagine the dinosaur Brontosaurus that weighed 16 – 22 tons and was 21 – 23 meters long evolved in

dinosaurs weighed 30-50 tons and had a body length of 30 meters. Sauropod dinosaur species then evolved beyond their lung capacity, hollow bones, and metabolic capacity.

Carnivorous dinosaurs such as megalosaurus, allosauridae, carcharodontosauridae, neovenatoridae and tyrannosaurus then evolved to become top predators of the giant food chain.

It is believed that all dinosaur bodies would have grown in size over time if the asteroid had never hit Earth. But the big body does not go hand in hand with the development of the brain.

Even before the Cretaceous Age or 80 million years ago, the brain of a tyrannosaurus only weighed 400 grams. The velociraptor’s brain weighed only 15 grams. Both brains are even lighter than the human brain which weighs an average of 1.3 kilograms.

Because they believe that the evolution of dinosaurs will stop due to the failure of the development of their brains. Although evolution has stopped, scientists believe that dinosaurs used to live in their respective herds.

Herd life shows the complexity of dinosaur life. But the herd’s life would also come to a halt because of its underdeveloped brain.

But scientists believe the dinosaur’s brain can continue to grow. Although it continues to grow, there is little evidence that dinosaurs may have evolved human-like intelligence.

Unlike mammal species. Although mammals could evolve, they would never evolve into giant animals. The brains of mammals also continue to develop, including killer whales, chama whales, whales, elephants, leopards and monkeys.

Because of this, scientists say that the evolution of mammals, including primates, cannot be avoided. In Africa, the area that scientists believe is the place of human evolution, encouraged human ancestors for seven million years to be able to survive and use various ancient tools.

Scientists also believe that humans evolved because the African environment encouraged brain development, the use of tools to walk upright.
