Could Dinosuars have evolved like humans if they had survived the mass extinction event?
To put things into perspective it only took us 7 million years to evolve from apes into modern humans.
Now imagine how 65 million years of evolution would've changed the anatomy of dinosaurs if they evolved like us.
In order for any species to become a tool building civilization it would require them to have atleast the following features:
2) Long arms
3) Grasping hands with sensitive fingers and opposable thumbs
4) Binocular vision
5) A large brain
Bipedalism gave dinosaurs a head start on mammals in the race for intelligence. Like the hominids, having discovered that they could run on their hind
legs, they must eventually have realized that their forelimbs were freed for the manipulation of objects.
Just like our ape ancestors having a decent pair of arms would've been a major benifit. If the arms played a functional role that contributed to their
survival then dinosaurs could also have been able to use their arms for more complex tasks like using stone tools.
In order to grasp something one of the digits, the thumb, should be opposed enabling its tip to touch the tip of the other digits. opposed digits were
very common in dinosaurs. Most theropods would typically use their hands for grasping prey and climbing trees.
Binocular vision is the ability to direct both eyes simultaneously at an object.The importance of this ability for the growth of the brain is that it
allows a better judgment of distance. It is well known that many Theropods such as Velociraptors & Troodons had binocular vision which allowed them to
easily spot prey from a distance.
The popular idea that the dinosaurs were dim witted, with brains no bigger than a ping-pong ball is only partly true. But it is not true of many
others dinosaurs, the ones noted above with the grasping hands and binocular vision, the smaller, agile coelurosaurs and dromaeosaurs that lived late
into the Cretaceous period. Knowing what we do about these, it is not so surprising that they had evolved large brains to coordinate their
sophisticated movements and vision.
On my final note I think it's entirely possible for dinosaurs to evolve like hominids did.
There are many speculations over the years of what dinosaurs would've looked like if they did evolved into a humanoid form here are just some artistic
depictions I found online.
