Like the suture line in ammonites, he uses the septal structure in the corals to retrace their evolution. |
But where's the EVIDENCE that the septal structure or suture lines are genetically determined? |
Where's the evidence that they're not? They're definitely inherited from generation to generation.
| Quote | | Why do you think I keep asking you how many base changes are required to change the identity of a vertebra, a much more complex structure than either of these? |
To change the subject after your embarassing attempt to falsify Schindewolf by "evidence" you refused to back up.
| Quote | | Quote | | Notice the transition from 'b to c' and 'b to f', |
So how many mutations are required for this transition? How many mutations are required for the transition between a cervical vertebra and a thoracic one with ribs? |
You tell me -- you're the expert.
| Quote | given what educated people know about developmental genetics.
...
What was known about inheritance at the time Schindewolf wrote this ...
...
Where's the evidence that shows that it cannot be bridged by a single base change?
...
Why would single mutations yield "gradual, smooth transitions" anyway? |
So you've found Schindewolf's mechanism.
Bully for you!
