Humanity, you felt for MacQuirk as you ought to do, and if you had beencontented to assist him indirectly, without anotorious denial of justice, or openly insulting the sense of the nation, you might have satisfied every duty of political friendship, with- out committing the honor of your sovereign, or hazarding the reputation
hmm?? Friendships

So, I read up on this just to answer this question. In basic terms, it revolves around natural selection. Natural selection is simply when the organisms that are 'better adapted' live on to pass on their genes. The animals that aren't the 'better adapted' have to find ways to survive. This is what leads to the development of these relationships. For example, small insects may climb onto animals to get food. The organisms support each other. Does that help?
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
