That's the scientific process at work. Theories are developed, research, tested, and published for other to examine and challenge. Sometimes the theory is found to be inaccurate and is replaced with a newer theory. Often the additional research supports the original hypothesis. All science, including evolution, goes through this.
Why isn't a similar process used in intelligent design or creationism?
They'd have to find a different species of Bible. LOL!
It's time to abandon the "mechanism" hypothesized two centuries ago and take a good look at what's really going on at the cellular level.
