Yeah, facts. What do they prove, eh?

Rob writes:

Exactly what I said in the other thread...

Dr A writes:

You maintain that facts don't prove anything?

Rob writes:

Exactly the opposite...

Well, it's a good thing I brought all this popcorn.

Do carry on. You are most interesting --- though not for the reasons you'd like.

Edited by Dr Adequate, : No reason given.

They often prove that our philsophical constructs are invalid. Where are you coming from?

Concluding This Topic
None of the recent posts show an interest in the thread's topic, so I think the next step should be for you to repost the thread's conclusions so it's the last post, then I'll close this thread.

Conclusion
The conclusion is that there is no one overall theory of evolution, but we can arrive at a statement that is a synthesis of numerous tested and validated theories for how evolution happens. This can be stated at different levels of detail as follows:

Message 158
(1) The modern theory of biological evolution is a synthesis of several validated theories on how species change over time.

(2) The modern theory of biological evolution is a synthesis of several validated theories on how species change over time; it includes theories on how change is enabled, and it includes theories on how changes made within each generation are selected.

(3) The modern theory of biological evolution is a synthesis of several validated theories on how species change over time; it includes theories on how change is enabled, due to the available variations (diversity) within populations from the formation and accumulation of different mutations in hereditary traits, and it includes theories on how changes made within each generation are selected, due to the differential response of organisms under prevailing ecological pressures to their individual development, their ability to pass on hereditary traits to the next generation, and their opportunities to disperse into other ecological habitats.

(4) The modern theory of biological evolution is a synthesis of several validated theories on how species change over time; it includes:

  • theories on how change is enabled
    ...(list of theories on different mechanisms for the formation and accumulation of different mutations in hereditary traits within populations)
  • theories on how changes made within each generation are selected
    ...(list of theories on different mechanisms of selection and where and when they operate)
    ... etc

Now it may be interesting to flesh out #4 with the lists of theories from natural selection to genetic drift to punk-eek to runaway sexual selection ... etc.

Evolution is the change in hereditary traits within populations of species over time, and these theories explain different mechanisms and processes that occur. These theories also explain the existing evidence known from genetics, lab and field studies and the fossil record.

One could say that the overall theory of evolution is that evolution happens, has happened and will continue to happen.

Enjoy.
