You're still contradicting yourself. But considering your responses are just the same repetitive soundbites, you likely don't even realize where the contradiction lies.
This started with your claim that
"We can say there is a common design in life and it works just as well. Because we can use that common design to make all the discoveries we want.", in response to my discussion about applications of evolutionary biology.
I then presented a paper to see if you could demonstrate it:
Discovery of Regulatory Elements by a Computational Method for Phylogenetic Footprinting. Specifically the paper described an algorithmic approach to finding regulatory sequences in genomes using phylogenetic trees. Phylogenetic trees are
by definition a hierarchy of evolutionary relationships. And just for emphasis, this isn't merely a case of "commonalities". They show specific evolutionary relationships (i.e. which organisms share specific common ancestry) as well as data related to relative divergence times. This is about patterns not mere commonalities.
Your response was the lackluster,
"All those things you talk about are evidence of common design."
By this you are effectively stating that phylogenetic trees are somehow evidence for common design, which on the surface makes no sense. But I'll run with it and thus you are implying two things:
1) that phylogenetic trees are valid hierarchical relationships of different organisms; and,
2) since phylogenetic trees are constructed on the basis of evolutionary relationships, if life was designed then it has the appearance of these evolutionary relationships.
IOW, you're basically saying that life has the appearance of evolution.
But when you turn around and claim that there is no evidence for common ancestry, you're effectively stating that phylogenetic trees are in fact
not valid. And if phylogenetic trees aren't valid, then they certainly can't be evidence for common design.
Now this would be the more logical approach for a creationist to take, since phylogenetic trees make no sense from the perspective of independently designed objects. Again, phylogenetic trees are constructed on the basis of evolutionary relationships. If you're saying those relationships aren't valid, then the trees themselves aren't valid.
But let's go back to your prior claim:
"We can say there is a common design in life and it works just as well. Because we can use that common design to make all the discoveries we want."
You're now in a quandary. The example I showed you makes use of evolutionary relationships via phylogenetic trees for genomic analysis. If you want to claim you can do the same with "common design" AND reject evidence for evolution at the same time, you need to come up with a valid substitute instead of phylogenetics. But you don't actually have one do you?
Consequently your claim about using "common design" for scientific inquiry is false.
Thus you're stuck repeating contradictory sound bites ad nauseum without even realizing those contradictions. It's like you're the creationist equivalent of Schrodinger's cat, only simultaneously affirming and rejecting evolution.
