I reckon the beauty of our class exercise lies at the tail end of the essay question: "What examples would you present to illustrate how pervasive this is in the living world?"
Indeed it is a living world, at least according to some. Perhaps all living things comprise one biological entity, one large functioning ecosystem (life-force) with planet Earth as skeleton. Has been denied by many. But Lovelock thought so. Margulis supported it. Heck, maybe Lennon did too, "I am he as you are he as you are me. And we are all together" ("I Am the Walrus"). It really depends on one’s definition of "life", on what a discrete "species" or "individual" is, how you view "time". It is fine if you don’t want to believe in Gaia, but for the sake of this essay try to entertain it…or something similar.
OK, right, so Charles’s work suggests we all came from one common ancestor. And if evolution as we know it is true, then every living thing that was and currently is, is from the same "seed" or "stock" – in a way it’s the same organism. Contained molecules, appearing and behaving differently in space and time. Somehow, the prokaryote we (likely) evolved from is our great, great, great…grandmother.
1) Life is connected because it (likely) comes from the same, single prokaryotic origin. Information with function passed down and modified over time. It’s all one force. Each bit of it, interacting with other bits of it, to sustain it. You’ll notice the "tree of life" is composed of many branches but its still just "one tree." One Life.
Life doesn’t die (at least not yet); it falls apart (is digested). The organic matter is broken down, recycled into remineralized nutrients ("dust to dust"), and then rearranged by "life" as it evolves. So as each component ("individual" of a "species") falls apart, it gets recycled back into the system. It supports itself, regenerates itself, transfer pieces of itself around to other parts of itself.
2) Life is connected because the atoms that compose it are under constant rearrangement; shuffling through different components, or between what were "living things" to other "living things." Much of these rearrangements are made possible by microb
