Definition of relative dating of fossils
The thermodynamics argument against evolution displays a misconception about evolution as well as about thermodynamics, since a clear understanding of how evolution works should reveal major flaws in the argument.
Evolution says that organisms reproduce with only small changes between generations (after their own kind, so to speak).
In any nontrivial system with lots of energy flowing through it, you are almost certain to find order arising somewhere in the system.
If order from disorder is supposed to violate the 2nd law of thermodynamics, why is it ubiquitous in nature?
This is not a problem for evolution because evolution doesn't propose occurrences even remotely like that.
In fact, if we ever observed a frog turn into a cow, it would be very strong evidence against evolution.
"Evolution violates the 2nd law of thermodynamics." This shows more a misconception about thermodynamics than about evolution.
Evolution makes predictions about what we would expect to see in the fossil record, comparative anatomy, genetic sequences, geographical distribution of species, etc., and these predictions have been verified many times over.The number of observations supporting evolution is overwhelming.What hasn't been observed is one animal abruptly changing into a radically different one, such as a frog changing into a cow."Evolution has never been observed." Biologists define evolution as a change in the gene pool of a population over time.One example is insects developing a resistance to pesticides over the period of a few years.
