This is probably the most accessible explanation of the 2nd Law of Thermodynamics I've ever read.

It's put together by an emeritus Professor of Physics, and manages to be both a) intuitive and b) correct.
In a "sequel" website, Dr. Lambert also discusses evolution with regards to the 2nd law:
Just a moment...
Note this is from someone with no professional association with evolutionary biology, but rather a physicist.
Finally,

is written by a Chemical Engineer/Evangelical Christian, who says both of the following:

I am an evangelical Christian. I believe the Bible to be entirely trustworthy in conveying God's messages.

So some creationists, recognizing that their argument fails for the thermodynamic entropy, assert it in terms of the information entropy, which talks about things related to "complexity" and "disorder." It still doesn't work. First, there are real problems, without satisfactory solutions thus far, in quantifying the information entropy of living things. Someday this may be do-able, but right now science is not sufficiently well-developed to make definitive statements with regard to information entropy and life. Second, the first flaw mentioned above still applies in that the systems under consideration are not isolated. This means that, even if one can apply a "second law" to them, it will not be in the simple "entropy must increase" form valid for isolated systems. Finally, I can mention that, contrary to statements one finds in the creationist literature, cases are known in which genetic "information" (by some reasonable definition of the term) in living creatures can increase via natural processes.
