Quote | On the other hand, let’s look at an evolution example. An evolutionist uses DNA sequence data to construct phylogenies. First, the data are processed to cull homologous sequences, thus rejecting differences. Then the analysis is rerun several times to hone the results, and remaining outliers are explained as a consequence hypothetical evolutionary scenarios. The results are published, and later become strong evidence for evolution and we use them to confirm our flimsy conclusions. |
There's a lot to say about this paragraph, but since I'm tired and irritable, I'll give you time to support this statement if you wish. Just two questions:
If molecular phylogenies are simply exercises in forcing the evidence to match preconceived ideas, then:
1) Why do the molecular trees surprise scientists so often, and
2) How are these phylogenies able to predict patterns of SINE insertions? The Afrotheria hypothesis was validated by retroposon evidence, and while it's true that the authors posit a "hypothetical evolutionary scenario" to explain a possible discrepancy caused by one insertion, the overall pattern supports common ancestry for these mammals. |

What an ignorant fool.
He must have gone to the Paul Nelson school of molecular phylogenetics.
Nelson once claimed that the order in which a taxon is placed in a dataset and then aligned will dictate its position in the phylogeny, that experimenter bias essentially produces the desired outcome.
So, I took a dataset that I had been working on at the time, scrambled the order of the taxa in the alignment, coded their names, and removed all gaps. I offered to send him this dataset, provided links to free software with which he could align them himself, and to free phylogenetic software that he could then run his dataset through. I wrote that if his outcome was different than the outcomes that I got with that dataset, then he might have a point worth discussing.
But...
Darn it, he just didn't have the time...
... to test his claim....
But he went right on making it.
The more I read, the more I am convinced that these people are just plain old pathological liars.
