Can you answer the question: What tangible benefit does teaching students Darwinian evolution produce? If you attended a college or university, did you study evolution in any of your courses.?
While there are many direct benefits to knowing evolutionary science that several of the people in the thread have already gone into, the study of evolution can be a very good "test case" to teach students about how the scientific method functions: how initial evidence can suggest a hypothesis, which then suggests a method, which leads to observations and conclusions, which must then be reconciled with other science.
In this regard, it's a lot like the study of history: it's often less about the actual subject and more about things like critical thinking, judgement, and learning
the process of figuring out what's happened in the world.
A person who has a very good understanding of evolution will be able to apply the same scientific principles to just about anything, and will have the basic mental tools to understand and interpret just about any scientific proposition. That's immensely valuable to anyone, IMO.
jarofthoughts,
Is teaching Darwinian evolution ever "relevant". Once again, you couldn't list any tangible benefits. Darwinian Evolution is a circular theory, sort of like you need to learn it to understand it. You label it science, but the point is that any other "science" has produced tangible benefits to society: knowledge and understanding of the human body has helped doctors cure patients, knowledge and understanding of atoms has allowed chemists to produce useful materials, knowledge and understanding of electromagnetics has allowed engineers to create radios and televisions.
Darwinian evolution appears to have produced no such tangible benefits, although it has been around a long time. This belies its title as "science".
I'm a civil engineer. One aspect of my job is minimizing the effects of urban development on the surrounding ecosystems. Without the science of ecology, I wouldn't be able to do this. Without evolution, there is no science of ecology.
You say you're an engineer; if so, then you know that it's part of our professional duty to know and understand the effects of our professional decisions. If we don't understand how our engineering decisions can affect environments and the species within them, then it's impossible for us to fulfill this part of our duty.
As an electrical engineer, I understand that your immediate work may be somewhat distanced from the natural environment, but hopefully you realize that the larger context of the projects you work on - whatever they are - does have implications for the natural world.
If you're going to understand the full implications of your work - and I would argue that every engineer has a duty to do so - then you need at least a basic understanding of biology, which includes a basic understanding of evolution.
Unless you can state a tangible benefit, then that's at least one vote for no tangible benefits. It will only make sense for me to respond again if you at least attempt to list a tangible benefit.
You might as well be asking for a tangible benefit of the differential equation.
Evolution is the theory that allows biology to make sense. I once heard a quote that struck me: "without evolution, biology is just butterfly collecting." Without a knowledge of evolution, you can examine living things and describe their function, but to understand them and the inter-relationships going on in the natural world, you need evolution.
