What is the most basic/essential piece of human nature?

I think the greatest difference with humans and animals we are more educated. We have the ability to read and write and they do not. We go to school and learn. We grow and grow mre each year. We don't just grow physically like animals, but we grow mentally. We are able to purchase houses and stock; we also learn how to get and keep a job. Animals have certain instincts that helps them survive, but they can't get educated like we can. We can easilt communicate with each other, and we speak many different languages. Who is to say that animals can or can't communicate with each other because we really don't know since we are humans. Seems like animals can communicate with each other or it would be difficult for them to continue on, but they're language is probably a lot simpler than ours. They don't get educated on grammar and where commas should be and all that like we do.
