[Taxacom] DNA contamination

[Kim van der Linde]

Yeah, when I did the supermatrix analysis of the drosophilids, this was 
one of the issues we ran into and that we addressed in the supplementary 
ascension code data table,

I think when you get a weird outlier, it is always advisable to 
re-sequence it extra careful to be sure it is correct. I do that with 
reviews as well, suggesting that they double check certain species when 
it looks like a weird outlier.

Another example was recently published in the last Pantera phylogeny 
article, which explained some of the phylogenetic inconsistencies that 
had plagued that genus.
