Actually HappySqurriel your demonstrating my point quite nicely in that you think these subjects aren't interconnected. Which is usually the last desperate hope or outright denial I hear when I bring up this point. Basically the people who go off on their tantrums do actually know that they don't know. Somewhere in their head the also know that they never wanted to know all along. They have no argument and they have no defense. That is why it seems to hurt them so much. You can almost always keep your cool when you think your in control, but when you find that you are helpless thats when you usually go off the rails.
You need to brush up on geology, because life is a expert rock builder. Be it Limestone, coal, petroleum, and a plethora of crystals. Natural Selection is at the heart of why it happens, and where it happens, and where things can be found. To be blunt understanding the evolution of life on this planet is as fundamental to understanding geology as Volcanism, Plate tectonics, and erosion. Without life you don't get a state like Florida which is built of limestone. Basically the carcasses of dead sea creatures. We can readily see this, but Natural Selection tells us why this habitat allowed for this to occur. Further more Natural Selection can look at the planets record, and say look for this biproduct of biology here, because swamps don't grow in places that were mountains, and oil doesn't form in places that were never oceans. Any prospector looking for oil or coal in virgen territory isn't going to be long for a career without a rudimentary knowledge of paleogeology.
Archaeology has more to do with Natural Selection then you think, because human beings aren't seperate from the forces of natural selection. Alterations in the biosphere has had profound impact upon the culture and the very survival of past cultures. Without understanding the connection between a ever changing environment, and the people that live there your missing something incredibly critical. Look to late Ice Age settlements many of which can now be found under water, and see how the change in environment altered the flora and fauna, and see how the human population was forces to respond. Look to Meso America and the Mayans. Many leading theories ascribe the fall of the civilization to ecological catastrophe, and then compare that to the modern populations in the region.
Going onto psychology I can't believe you are unaware of this. Natural Selection has been applied to the human condition almost since its inception. There is a reason we look to our primate cousins to understand the origins of our own behavior. Why do our brains function in certain ways while not functioning in other ways. That might on the face of it seem more beneficial. Why do we share similar psychological phenomena like common dreams. This field even has a name Evolutionary Psychology. Go and look it up.
Anatomy I swear this one really fucking shocks me. Anatomy is the study of the structure of living things. Quite frankly it has been said that there is no understanding of Anatomy without a understanding of Natural Selection. Living things are riddled with illogical contradictions. From difficulty in child berth for humans, to hiccups, to gill slits in fetuses, to the propensity to herniate. I could just rattle these babies off all day, and Natural Selection is that explanation it isn't even optional. Ask any reputable Anatomist.
Meteorology this is the one we are bombarded with every day. Plant life is an extreme arbiter of this planets atmosphere. Just going beyond the fact that it pumps millions of tons of Oxygen into the atmosphere every day it also sequesters water, alters the thermal signature of the ground, and removes kinetic energy from the wind. Understanding how a bioshpere is going to change in response to a changing environment is crucial to understanding future weather patterns. High end computer models have to take these effects into account. The weather isn't just up in the sky its at ground level.
Sociology, you actually said Sociology? Eugenics, and Social Darwinism don't ring a bell. Hold up I just got a call yeah this is the holocaust calling, and saying what the fuck. You have to be shitting me Sociology and Natural Selection have been dancing together since day one of print. Usually giving people bad ideas, and weak justifications to do some pretty evil shit. That said respectable Sociology incorporates no value base when it comes to Natural Selection. It is used pretty effectively to understand group behavior like the mob mentality, and frankly without Natural Selection it would be a complete mystery. The behavior is basically logically in the past sense, but not in the present sense.
You really need to read up on the subject, because your just not tying everything together.
