I think it's rather a PR-issue what science suffers from.

Many, if not most, scientific theories aren't as easy to comprehend as people think they are.

If scientists try to explain something to someone without any clue in that particular field, they drop things to decrease the complexity.

This is also the case for evolution. A scientist 10 years ago would explain the concept of evolution just as he would today. But that doesn't mean science and the understanding of the process of evolution did not advance in that period of time.

Scientists are studying their whole life, and it's just not possible for them to share their knowledge with someone who didn't have the same experience.
