Dawkins doesn't understand the second law of thermodynamics. We know that the second law is valid, hence we know that evolution does not contradict it. The complexity of life does not come from the energy of the sun, as Dawkins mistakenly thinks. It comes from the complexity of the sun. It is not evolution that violates the second law, it is the theory of natural selection that violates the second law.
You are taking two different definitions of entropy and confusing the terms, one relating to thermodynamics and your version which relates to configurations. We'll distinguish them as "Thermodynamic entropy" and "Configurational entropy."
Classical entropy, which is thermodynamic entropy, refers to an isolated system as it relates to 2LoT. This doesn't conflict or invalidate natural selection because the principle that entropy can only increase or remain constant when it is applied only to a CLOSED system. Is the Earth a closed system? Whenever a system can exchange heat with its environment, an entropy decrease of that system is entirely compatible with the second law. So since the earth is clearly not a closed system, what does it have to do with your argument? I'll spare the suspense. It doesn't.
Your version of entropy relates to configurational entropy, that is, that all things tend towards disorder when left to itself. In a sense you confuse Boltzmann's constant with Claude Shannon's theories on
information loss. Though they have similarities in how loss works, they aren't the same thing.
So when referring to entropy from now on, you might want to distinguish between the two kinds of entropy. 2LoT and evolution have nothing to do with one another.
Information loss and heat/energy loss are similar, but they aren't the same thing. Please stop saying things like evolution violates the Second Law of Thermodynamics because it's just not true. If you want to use the term "entropy" to clarify your point, do so without falsely introducing 2LoT.
