That's preposterous to assume that testing a hypothesis would interfere with your job or require training.
Are you not willing because of your false assumption, or because you don't want to know if your hypothesis is false?
But you'll understand the science far better if you test hypotheses for yourself than if you depend on others to correct your glaringly mistaken assumptions. False hypotheses still help us learn.
That's not what any of us are referring to. The misunderstanding of basic biochemistry and structural biology is yours, not ours.
Instead of depending on hearsay, why don't you look for yourself?
Me: are the crystallins in the lenses of your eyes categorically different from all amoeba proteins?
Your assumptions are not helping you. Test your hypotheses!
That depends entirely on how you define "function," as Swamidass told you. That's why you learn more when you test the empirical predictions of hypotheses, even if others have already done so.
