science has been unable to demonstrate the molecules to man scenario, correct.
Ahhh but the problem is, they didn't, "discover" the notion that molecules will become men, for they do not. Therefore, "science" accepts unfalsifiable gibberish stories.
science has identified why it hasn't been able to demonstrate it though.
at one time i would've said you are right.
The problem is one of delineation. You must discern that which is the baby and that which is the bathwater. I am not throwing out the baby with the bathwater for I accept all of the things which operational science has uncovered, but the problem is, historical philosophies are enjoying the REPUTATION of operational science, but they aren't operational science!
evolutionary theory was indeed based on historical events, some of which could never be proved.
in my opinion, the current change in evolutionary theory is going to change all of that.
epigenetics is proof evolution is an operational paradigm.
it's my opinion that epigenetics will be found to be the primary force of evolution.
macro evolution will likely be found to be the result of epigenetics not being able to stabilize the genome.
this will result in a cascade (series) of major changes.
the above opinion of mine fits well with available data.
