Well, I think everyone knows by now that the case for macro-evolution is not very well supported.
No species evolved to from an entire other group of species. We simply do not have the physical evidence of this.
I would like someone to show me clear evidence of one species transitioning into another with clear stages of skeletal development etc. I will be open minded, without saying it's impossible. But at this point I really am not convinced that macro evolution took place.
That's my 2 cents worth.
