Why do scientists believe that dinosaurs are related to birds?

Scientists have discovered that the tissues used to produce scales in reptiles are similar to those that produce feathers in birds. This suggests that there is a common ancestor between dinosaurs, birds, and reptiles.

What is the stupidest bird?

Kakapo
Making it on the list as the dumbest bird, the Kakapo, out of New Zealand, is a parrot owl. The species is a large flightless bird. A night animal, this ground-dwelling bird belongs to the Strigopoidea super-family endemic to its home country. The bird’s also incredibly stupid.

How intelligent were dinosaurs?

Dinosaurs evolved into modern birds and some of them are extremely intelligent. In Japan, there are crows that have learnt to use the traffic to crack the shells of nuts that they drop – and they will wait for the lights to turn red, so they can safely retrieve them.

Why aren’t birds as intelligent as humans?

One reason that birds still aren’t as intelligent as humans is that a heavy, energy-hungry brain doesn’t mix well with birds’ main adaptive advantage – flying. It’s important to realise that intelligence isn’t the goal of evolution, nor is it always the best adaptation to the environment.

How big is a dinosaur brain compared to a human brain?

Dinosaurs had smaller brains relative to their size than birds or mammals. Diplodocus had a brain weighing 100,000 times less than its body weight. Compare this with a small bird’s brain, which is only 12 times lighter than its overall weight. The brain of an adult human is about 40 times lighter than its body.

Did dinosaurs have brains bigger than a walnut?

It didn’t help that one of the earliest dinosaurs to be discovered and classified (the above-named Stegosaurus, in 1877) possessed an unusually small brain, about the size of, yes, a walnut (its brain was so small, in fact, that paleontologists once speculated that Stegosaurus had a supplementary brain in its butt).
