Kropotkin Was No Crackpot:
What is not so often mentioned is cooperation between species - symbiosis - now believed to be pretty ubiquitous.
An example is the human relationship to its gut biota, essential for health. I think there are thought to be more microbial cells in the human body than bodily cells.
Symbiosis is so prevalent that it has been questioned how far organisms can be usefully distinguished.
Our very cells are derived from symbiotic interactions many millennia ago.
We cannot separate ourselves from our biological and social context. We would not have been able to develop our sense of being individuals if it was not for that context.
