Here are all four definitions of "religion" from Dictionary.com:
Dictionary.com said:
1.a Belief in and reverence for a supernatural power or powers regarded as creator and governor of the universe.
1.b A personal or institutionalized system grounded in such belief and worship.
2. The life or condition of a person in a religious order.
3. A set of beliefs, values, and practices based on the teachings of a spiritual leader.
4. A cause, principle, or activity pursued with zeal or conscientious devotion.
Now I don't think ANYBODY argues that evolution fits with 1... There is just no particular "supernatural power" or "creator and governor of the universe" in the theory of evolution. Theistic evolutionists ascribe TO a religion by believing in the supernatral God and his son Christ, but that's entirely aside from evolution in most cases. At least I've never HEARD a Christian say that their Christianity is based on evolution in some way!
Number two isn't really a definition of "religion" but is a descriptor of somebody who is IN a religious order. This doesn't apply to evolution unless evolution can be shown to be a "religious order" so again, we'll move on.
Number three is more vague. Does evolution point towards a particular set of beliefs and values? I argue no. Evolution has been USED as the justification for some horrible things (such as genocide) and "social darwinism" was used to suppress lower social and economic classes. However, it was never the evolutionary biologists who promoted these things! These conclusions were created by the propagandists (like Hitler) or by those who sought to perpetuate class division.
In the end, evolution is a DESCRIPTION of how populations change over time. It even describes what WILL happen in the case of genocide or some kind of misguided artificial selection. But never does it make ANY kind of value judgement about whether genocide or selection is bad OR good. In fact, evolutionary theory predicts the general outcome of a population that has few selecting factors JUST AS WELL as a population that is strongly culled.
Can people make judgements based on this information? Absolutely! Does the prediction of how a population will evolve SUGGEST one particular course of action over another? Absolutely NOT!
Thus number three is also not applicable. The values and beliefs are simply not based on the teachings of any person or more importantly on the teaching of a theory. Nowhere in the prediction of how a population will change is there any HINT of a suggestion that we should try to artificially direct this change. Perhaps more importantly, nowhere in this prediction does the theory make any judgement about what is "better" or "worse" from a moral or ethical point of view. We, as humans, might be better or worse adapted to our environment, but when has our ability to survive cold weather without clothing or survive in a desert far from water been lauded as a reason to make humans change faster by killing those least suited to the environment? Such a ridiculous suggestion, even if it were made, would be based not on evolutionary theory which PREDICTS the outcome of a certain selection. It could only be a conclusion based on the ASSUMPTION that better adaptation to dehydration is better for humanity. Evolution is a tool, not a paradigm that suggests one outcome is better than another.
Finally, definition number four is laughable. It conflates the definition of religion to anything people enjoy doing or do with a lot of energy... I've written quite enough, so I won't waste more of my time or yours explaining why it's so worthless in this context.
