What has allowed humans to get continuously better at collective learning?

Symbolic language

Explanation:

Collective learning is the human ability to educate and teach one another, and gain knowledge and achieve goals together. The ability to develop and to get better at collective learning has come first from language and intelligence, and later from what is known as “symbolic language”

Symbolic language is the human ability to imagine, represent, and communicate various concepts and ideas. This kind of interaction is particular to humans and allows us to understand and convey ideas, concepts, feelings, and emotions that are not directly stated. Through symbolic communication, we can use various symbols and metaphors to represent different meanings, and the person to whom we communicate will understand them.

As this complex communication got better and more developed, people could represent ideas more, and, therefore, get better at collective learning.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
