Let's see where this goes.

Great apes are not able to pass on their knowledge to the next generation or even to their own generation. This has the effect that each generation of apes starts again at level 1, be it behaviour or general knowledge. This lack of key ability makes apes very different from humans. For this reason, apes do not progress and cannot develop culturally. All knowledge that an ape acquires in the course of its life is lost when it dies. For example, if an ape wants to crack a nut, it has to learn it on its own and find out the best nut-cracking technique for itself, even though its parents are experts at cracking nuts. Humans have the advantage of not having to start from level 1, because we have the ability to pass on knowledge and thus develop it over generations. In itself, our intelligence is not much greater than that of a great ape. However, the decisive difference is that we can expand our intelligence. So if a person acquires knowledge in the course of their life, this knowledge can live on even after their death, provided they pass it on. So if a person wants to crack a nut, they develop a technique for doing so just like an ape, but unlike an ape, they pass this technique on. This gives other people and future generations the opportunity to hone this technique. Even today, we can still crack a nut by force, for example by placing it on a table and hitting it hard, but we all know that it would be easier with a nutcracker, which could also open the hardest nut to crack. So a big part of progress is developing knowledge and then passing it on. Only by passing it on is the progress you make a contribution to the progress of humanity.
