Why haven’t other animals evolved into ”smarter animals” like us humans have, if we originally came

I didn't even know animals had any smarts until I got one. That shows you how dumb I was. The ape. As always.

Hominidae include very intelligent members from Orangutans to Chimpanzees and each as about equal in intelligence except humans. All non human apes are very very smart. Humans evolved language ability and our brains grew to accommodate it. IMO, that is the main reason for the differences. When H. erectus began developing language as evidenced by growth of spinal chord for lung control, they gradually developed bigger brains right until modern humans evolved. There is only one animal on earth that has a language like ours and if there was another, I suspect it would intrude on the niche of the other meaning it would be a competitor and a threat and one or the other would probably survive.

Smarter is neither a goal of evolution nor the ultimate trait.
Speed, strength, mimicry etc are often more efficient.

Usually, intelligence evolves just enough so the predator is slightly smarter than the prey, More would be a waste of energy.
Example: human brain weighs only 2% of our body mass, but burns 20% of our energy.
That means the smart hunter has to get 20% more meat than the stupid one

Intelligence is only beneficial when facing very challenging conditions
Human intelligence has been beneficial during quaternary violent climate changes (when it's suddenly becoming cold, inventing fire and clothing is a good alternative of migration or waiting thousands of years for evolution giving us a thick fur).
As a consequence, humans are so (successful that we are now overpopulated, while our chimpanzee cousins are endangered.

Sometimes when not regulated by natural selection evolution is carried away and may produce abnormal traits, especially traits selected by sexual preference (peacock tail, narwhal tooth...).
Intelligence above than strictly necessary might be this kind of abnormal evolution.

Other animals show a higher than expected level of intelligence: octopuses, cetaceans, corvid birds.

Other apes have evolved other skills like strength (gorilla), tree climbing (orangutans) etc.
Seems intelligence had been the winning wager of the recent millions of years

Intelligence is found often in species that live in large groups, where group dynamics is essential for group survival. Knowing one's place in a social hierarchy, being able to coordinate activities, and protect each other all act as spurs to the growth of intelligence. Having a big, complex brain requires lots of energy: the kind of energy not supplied by food sources like leaves, and grasses. Protein is the key. If it's not a large part of your diet as a species, the chances of developing intelligence is extremely remote.

A part of evolution is adaptation. In humans, not being the strongest or the fastest, we evolved to be the smartest. But our intelligence is about different, separate adaptations that occurred at different times. Becoming bipedal is one. Using tools is another. There were many different drivers that forced us to become more intelligent and evolve into humans. For other animals, they would need to run into the same series of circumstances to evolve the same as us.

DO your research

and how do you know some haven't ?? man has been around keeping records only for a 1,000 years or so, and the animals have been around for over a million....

Foxes are evolving and wanting to be like dogs. There are plenty of you tube videos showing this. Even the foxes in the wilds of Russia are becoming friendly.

We are still apes and because we are one of kind.

Crows and dolphins are pretty smart, they just lack hands for making stuff. But it is a good question... (it doesn't disprove evolution but it is something to think about)
