We have a scientist saying everything is only a theory then saying evolution doesn't break a single LAW (which is untrue, btw). |
Well, a scientific law itself isn't even claimed as cold hard fact. A scientific law is simply a statement of repeated observation: "Every time conditions X are met, Y is observed, with no reproducible exceptions to that having yet been recorded." Laws are not written in stone. Newton's laws, as he originally conceived them, were simply wrong. They later needed to have conditions imposed on them, as science learned more about the universe.
As for evolution violating the laws of thermodynamics, that's simply not true. The relevant law here is the second, which can be roughly stated as "The entropy of an isolated system will tend to increase over time." The key word is "isolated." In scientific terms, that means that no matter or energy can enter or leave the system. A biological organism (or even the Earth itself) is not an isolated system. The order being created on our planet (or in ourselves) is at the expense of massive overall entropy gain.
Are you a scientist of biology/anthropology/paleobiology/geology? |
I received my Ph.D. as a Theoretical Chemist (statistical mechanics, thermodynamics, etc.) and now work in Biochemistry, modelling protein structure and function. Proteins are created in the body by directly translating the organism's DNA sequence (word for word, so to speak). It's possible to follow the mutation in function from one species to the next. As a new species (A) emerges and engages in new and different behaviour, you can see the DNA/protein sequence itself changed slightly from the parent organism - just enough to give an old protein a new function. A completely different, unrelated species (

which engages in the same behaviour but which descended from different species, will have arrived at that functionality from a completely different path. Thus, while the protein has the exact same function in both species, they are completely different proteins in terms of their sequence. Their sequences bear much more resemblance to their ancestor species than they do to each other.
If someone wants to study the evolution of species over the past few billion years, then they have no choice but to study the external wiggly bits on fossils and try to draw conclusions. However, if they want to study evolution of the species that are around us today, the evidence of it is written into the DNA sequences of the species themselves, just waiting to be read.
