DNA sequence data shows that this “living fossil” isn’t so fossilized after all

Living fossils are a tricky concept for evolutionary biology. In principle it seems simple: living organisms that closely resemble creatures seen in the fossil record going back millions of years. Usually they’re a single representative of a fossil record containing … Continue reading

RADseq and missing data: some considerations

Unlike Sanger sequencing, where loci are directly targeted for each individual and sequencing errors are relatively rare, massively multilocus datasets from next generation sequencing platforms are characterized by large amounts of missing data. This is particularly true for restriction digest … Continue reading

hyRAD and museum genomics

While the RAPTURE may have arrived, the development of novel restriction digest-based library prepartation techniques — and portmanteaus — continues unabated. In a paper published in PLoS ONE last month (and previously available as a preprint on bioRxiv), Tomasz Suchan … Continue reading
