We started the discussion about how crow has better cognition than sparrow, using a mirror test.
*Walking behaviour of sparrow and crowโฆ
Crow is smarter than sparrow because crow can walk forward and backward, as well as jumpโฆ
But in the case of sparrow it can only jumpโฆ that compared to crowโฆ
Sparrow and Crowโs mental ability was different, crow is very smart.
If we put the mirror into sparrow, they break the mirror, They canโt identify their ownโฆ Thatโs an example for mental ability of sparrowโฆ
Then we jumped in to the evolutionโฆ
We ( human beings ) are more flexible than monkeys and apesโฆ
Just looks the hand and thumb of monkeys, apesโฆ They are different from humansโฆ Thatโs also the part of evolutionโฆ
Then we discussed about our ancestorโs brain size and our ( Homo sapiens ) brain size,Our brain size is larger than most of our ancestorsโฆ
Our Ancestorsโฆ
- Dryopithecus,
Ramapithecus,
Australopithecus,
Homo Erectus,
Neanderthalensis
Homo Sapiensโฆ
Humans would have been extinct had we not possessed technological skills? 
And free hand movements including thumbs offered more manipulative skills?
Crows have disengaged motion than sparrow?
What is intelligence?
Some references that taken from the chatbox
Why Did Humans Lose Their Fur?
We are the naked apes of the world, having shed most of our body hair long ago
We also found that humans reach by far the highest manipulation complexity, even higher than predicted for our brain size. Human foragers occupy the most complex foraging niche of all mammals57, and forager diet requires intensive processing and relies heavily on enhanced manipulative skills58. common ancestor of human and apes - Google Search

These so-called hominoids โ that is, the gibbons, great apes and humans โ emerged and diversified during the Miocene epoch, approximately 23 million to 5 million years ago. (The last common ancestor that humans had with chimpanzees lived about 6 million to 7 million years ago.)common ancestor of human and apes - Google Search
few other animal list with flexible thumb. its not only human or apes or monkeys
One question in an animal cognition is whether animals other than humans have the ability to recognise themselves. A classic way of testing this, established in 1970 by Gordon Gallup, is the โmirror testโ.Crows take a look in the mirror - Scientific American Blog Network
