Okay, I admit, I was lurking!
I don't need to demonstrate those barriers because the burden of speciation proof is on you.
You lost me Herep. You seem to be suggesting (or quoting) that there are "barriers" that prevent morphological change. But "barriers" is a very vague word. It's not unreasonable to ask for a definition / example / mechanism.
Are you talking about something that exists within the genetic code? Are you talking about something that exists in physical world outside of the organism?
You're saying that the burden of proof is on evolutionists, but we've given you data, mountains of it. If you want to disprove the data, offer data of your own.
The burden of proof is on the party trying to change the status quo. Evolution is quite clearly the status quo. If you hold a different belief, please offer a clear explaination of your belief and data to support your explaination.
Otherwise, why should we take your theory any more seriously than flat-earth or boogeyman?
