Re: biological evolution
I'm glad to see this thread started.
I'm not competent to contribute much to it. But I'd like to see a PRATT addressed during the discussion.
A creationist might state that nature cannot create the "information" required to produce novel features and "macroevolution" . Dog breeding includes human intervention which can be viewed as being similar to an ID agent stepping in to add information allowing new features like wiener-dog legs.

Under a government which imprisons any unjustly, the true place for a just man is also in prison. Thoreau: Civil Disobedience (1846)
The apathy of the people is enough to make every statue leap from its pedestal and hasten the resurrection of the dead. William Lloyd Garrison

Re: Information
The amount of information required to transmit some information content over a lossless channel is equal to the amount of information content. If you have a 2 megabyte disk file on your computer then it will take 2 megabytes of information to transmit that file over a lossless channel.
The latter sentence cannot be right. Not every 2 megabyte disk file contains 2 megabytes of information. For example, a compressed text file contains the same information in both the compressed and uncompressed format. Yet the rules governing the translation from one format to another might require only a few bytes to transmit.
I'll note that the latter quoted statement does not follow from the former statement above regarding the amount information required to transmit an amount of information across a channel.
I have a vague recollection that we have discussed this issue before.
Of course the above should suggest that information and entropy cannot be inversely related as the entropy in a compressed and uncompressed file are different.

Re: Information
Zaius has cheered your post and ignored mine, so he must have interpreted your post as a successful rebuttal of my argument for a direct relationship between information and entropy.
I'm not sure why Zaius would think that. I did include a rebuttal of that argument. Maybe he just likes the idea that you were incorrect about something.
I wasn't referring to overhead and such. I'm referring to files that are compressible. Like 2 Megabyte files containing all zeroes as an extreme example. The information content of such a file is very small and we can transmit that information across a lossless channel in only a few bytes, even if we count the bytes describing the decompression algorithm.
