Experts can be respected in their limited area of expertise. I agree.
Why the presumption that their fields are limited? If you're looking for a broader remit there's likely someone who is an expert at that level.
But not when we need to look at something differently or when other factors need to be considered.
First you have to justify why you think there's a 'broader perspective', then you have to ask if you're talking to the right expert - look back to your attempts to use the output of a cardiologist to justify calling evolutionary biology's established findings into question.
Problem is that experts generally have a very microscopic perspective and cannot see the woods for the trees.
No, the problem is that you keep trying to justify presuming there's something more on no more basis than your personal incredulity.
I am not saying that just about anyone can comment on their area of expertise. No! However, other scientists and philosophers who have a bigger picture view can comment very constructively on the subject.
You're mixing philososphy and science here, and they are massively different fields of expertise. People can always comment constructively, can always ask interesting questions, but it takes something spectacular to overturn generations of well-established science and whatever that might be you don't have it.
Any area of study does not exist in isolation in the world.
And in my experience, experts in a field are pretty good at understanding how their field of expertise fits in - it's almost like expertise involves having a context.
It is a part of a bigger reality and it is necessary to see how it fits into the totality.
But what it doesn't have to do is to fit into your interpretation of the totality. If you want to overturn expertise and established science you need new science, not questions (valid or otherwise), woo and people talking outside of their own areas of expertise being used as attempted justification for throwing out the established scientific consensus on a question of science.
