Life is always changing. Everyday is always a different day. Humans and animals are adapting everytime and that’s what makes the universe expand. I was raised in America and nature is all everywhere, and everything is always changing. The way we talk, act, even lifestyles are all changing in time. As years change, humans are learning plenty. But it ain’t just humans that are learning. It’s animals as well. They change their lifestyles as well by learning. They way they upgrade their “wealth”, their lifestyle, their skill, etc.
