speaking of intelligence in birds:

Our brain is much larger than even a chimp’s brain. A lot more of our head is brain. A lot more of a chimp’s head is mouth.
Plus, we eat meat, and start its digestion by cooking it first. This frees more energy for our brain.
Then. we have hands. Beautiful hands. We can manipulate things better than most of our fellow advanced animals (I’m thinking of birds and the other mammals).
Then, there is our throat. We can speak. And, with words, there are ideas. Abstractions. And, with abstraction, there is reason.
Finally, there is our muscles. Our muscles are weak as compared to chimp’s. Our senses aren’t that good either. This means we cannot rely on our strength. Our ancestors needs tools to hunt, and also to hunt in packs. Hunting in packs that included wolves (who became dogs).
You’ll find hands like ours on some animals, and throats like ours on some birds. But, our combination and our enormous brain sets us apart.
The advanced animals are terrific, as is the entirety of creation. But we are the pinnacle of creation.

Yet humans struggled for survival, and only one species of human remains.
