I agree with what you said

with the "but" and "however" being the least
necessary key words in your essay. I have always thought a a semi-colon rather than a comma should precede "however" when it is a compound sentence. Besides that it doesn't matter much, do you think this is true?

Would you also agree with my zoology professor that many experiments, if they are not theory-laden, simply wasted experimental resources? I bet you would. Most of my comments here on the forum are as theory-laden as I can make them...
theory figures greatly in my thinking.

Cordially,
Mike
