Like a billion years ago, one cell literally vored another cell without killing it and became the first eukaryote. That is, the first cell with mitochondria. They evolved in tandem where one of them focused on providing energy to the other so they could both thrive and become greater than the sum of their parts.
Literally every animal and plant is trillions of predator × prey ships working to make a multicellular organism that can better interact with its environment.
