The slow, and sometimes incomplete, journey to diploidy

Whether you are reading this as a plant, an animal, or fungus, it is likely that some ancestor of yours doubled up on genomes. However, it is likely that these extra genomes disappeared over evolutionary time. What gives? Where are those extra … Continue reading

Sweeps and Demographic Inference

Population genetics presents us with numerous conundrums – several of which have to do with how the same genomic disposition can be “reached” over evolutionary time with multiple alternate demographic or selective processes. I have discussed several of these issues … Continue reading

One of these things is not like the other……

While we know that bacteria are pretty scandalous with their DNA, not minding horizontal gene transfer (HGT) and such (which can be pretty confounding when trying to discuss species concepts), and although it’s clear that this kind of genetic material … Continue reading

Island-Hopping with an E.I.D.

If you live in the U.S. and feel like Zika virus is getting closer to home, that’s because it is. Although there are no known cases of Zika transmission by natural vectors in the lower 48, experts have stressed that … Continue reading

New branches on the tree of life

(Trees from Darwin (1837), Haeckel (1866), and Woese (1990)) We’ve come quite a long way since Darwin sketched out his tree in 1837 connecting, with branch tips representing animals and microbes currently in existence and branches and trunks their ancestors. … Continue reading

Results of the Molecular Ecologist’s Survey on High-Throughput Sequencing

Some days ago, we asked our readers to fill in a survey (now closed) on your use of high-throughput sequencing techniques. We got a lot of responses, a total of 260 people filled in the form. Thank you! Here are the results of your answers. The … 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
