Why did no one understand how Hans could do such remarkable and unusual feats?

Animals

Explanation:

The number faculty is profoundly rooted in our biological ancestry, not dependent on our ability to use words. In view of the multitude of contexts in which we humans use numerical knowledge, life without numbers is inconceivable.

It turns out that processing numbers provide a major survival advantage, which is why this behavioural characteristic is present in many animal populations. Several research studying animals in their ecological settings indicate that the representation of numbers increases the ability of animals to access food sources, hunt prey, escape predation, navigate their habitat, and persist in social interactions.

Long description. This is the best I could do. Hope it helps. I did not quite understand your question. Sorry.

subject: why anyone can be a genius.

occasion: moving forward in life.

audience: average person

purpose: to push you further in life

speaker: many famous geniuses.

here is the poem:

here is thy, and here is thee, genius is for what he can be.

poem is a matter of rhyme, but like ben frank said, life is a matter of time.

we have great inventors such as thomas edison, who said, "genius is one percent inspiration and 99% perspiration." no, no perspiration as what comes from your skeleton.

we have great minds, from places of all kinds, such as yu kaw la chi tie, (now im switching languages because yu kaw was japanese.)

てちハラスイヒイス, てちラスイヒイス

てちのちみスイヒイス.

you are a genius, well not yet, but you are capable, and that is a bet.
