Naturally selected and intelligently designed

[this is my obsession with a concept, not an idea for an art project exactly]
I have, in the last month, become obsessed with natural selection. Every conversation I have, article I read, and project I work on has become about natural selection.
It started with a project given to me by Michael Rees, my professor in an individual study on Industrial Design, which was to do a complete analysis of an orange from a design aspect. Initially I thought it was ridiculous but then I started thinking: this orange has been design by natural selection- an unbiased, objective selector that has one goal: the reproduction of the species, and chooses the aspects of the orange (or plant or animal) based on whether they help to further the goal. Which means that every plant or animal we see on earth has been the best it has ever been in existence (with the except ion of the rare case of a bad mutation, which will work itself out in the long run). Which means every aspect of the orange has a reason for people there because if it didn’t help the orange reproduce, then it wouldn’t stay around- it would be replaced by something that did. The analysis isn’t important- the concept is.
I began thinking about human beings as being designed- t his came about in a conversation with my friend Mike. He was saying that human beings are so advances, etc- which is not a dumb claim- we can move very fast, we have opposable things, our eyes are pretty good, also our smell, hearing, etc. We have the ability to think quickly, problem solve, build tools, etc. However, I then began to think that for each of the things that I listed- there are other animals who do it better (except, maybe for, problem solving- but I’ll get to that later). Panthers run faster, hawks see better, dogs smell better, lions hunt better, etc. While we are very good building tools- just recently scientists discovered apes in the wild that had build spears to hunt- so we aren’t the only tool builders.
Now, as for problem solvers- it seems as thought that is what we are good at. because we have buildings, bridges, airplanes, clothing, computers, sensors, guns, bombs, etc. But this is where I started to question just how smart we are- what is important here? what is the goal? The subject human-centric goal seems to be- conquer as much land, influence others as much as possible, gain power over others, gain money, gain beauty, etc. However, the objective goal of existences, according to Darwin, is not that- it is to continue existing. How are humans doing on that goal? We are depleting our resources, killing each other, overshooting our population capacity for our land, poisoning our biosphere (that we depend on for existence) etc. So if Darwin is right about what is important, we aren’t doing so well. In fact, if you view earth taking a step back- and, from our scientific knowledge, that the earth has been around for millions of years before humans- then human beings will look like a little random mutation that wasn’t good for reproduction, a failure of a mutation, and that worked itself out (i.e. we worked ourselves out of existence). How? we fought against natural selection- our medicine and anti-aging procedures helped keep those not best suited for evolution alive. Our societies replaced physical work and exercise with machines and virtual worlds, so that we became dependent on electricity and things outside of our control for our basic necessities. We forgot how to hunt for ourselves, cook for ourselves, prepare our food, build shelter, etc. In ancient times, heavier women were celebrated because it meant they were better prepared to have children (wide hips)- today? not so much. Once you start thinking about it, more and more examples pop out in everyday life.
