DINOSAURS an always fascinating creatures which we hadn't even witnessed in our lifetime.WE all know the dinosaurs went extinct as a result of asteroid explosion.Asteroids are huge rock like structure that orbits the sun. Meteroids are the asteroids which survive the earth landing.Around 66 million years ago the day of extinction of dinosaurs excluding bird like dinosaurs is experienced.As the asteroid fell on the central coast of America,there was a huge explosion.A 93 mile wide crater is found in coast of mexico which is now buried under the sea floor. As a result,a huge number of dinosaur species went extinct.There is also a theory that there was a huge volcanic eruption in northern India leading to destruction of plants and blackening of sky which led to hebivore's destruction and carnivore's craving for food which results in extinction.Volcanic eruption intervened food chain.It is also said that the reason for their extinction could have been a supernova a star which is only few only a few light years away from earth may have exploded and destroyed dinosaur species. But now let's imagine that dinosaurs didn't go extinct as imagination is endless.

  Some say we cannot determine how the world would have been if the dinosaurs were still in picture.To know the endpoint we all need to know the starting point as all species don't evolve in a uni direction.Dinosaurs had evolved in its weight but it had weak trends in brain size.T-Rex brain size was about 400 milligrams. Human brain size is 1.3 kg.Mammals such as elephants,whales had a huge intelligence increase.But we can see how some scientists interpreted it.Some scientists say that they may have evolved exactly like human beings walking with two legs,going to moon,inventing telephone.Some say the world would not have much of a difference as human species would also have found a way for its evolution and become a dominant race. More than brain's size neuron distribution in brain shows the congnitive functions of that certain species.Mammals developed neocortex in which the neurons are arranged in a thin layer and one can communicate with other.Most intelligent dinosaurs were the troodons(bird like dinosaurs).There is also a interpretation that their species would not have lived this long and become extinct some million years ago.As there was not a significant increase in their intelligence there would not have be development like a society .And that may lead have made them ceas to exist.That's all for today.Comment your thoughts!
