Population genetics takes the “co” out of snake-newt coevolution (maybe)

A textbook example of predator-prey coevolution could need revision, if the conclusions of a recently posted pre-print hold up more broadly. The manuscript, lead-authored by Michael Hague with Amber Stokes, Chris Feldman, and Ed and “Butch” Brodie, calls into question … Continue reading

“It takes all the sequencing you can do, just to keep up with coevolution”

One of the most fundamental observations of evolution is that it never seems to stop. This is particularly true in host-pathogen coevolution, in which each species must adapt in response to the other. This constant evolution is the process biologists … Continue reading

Symbiotic organs shaped by distinct modes of genome evolution in cephalopods

Last week I was whining about gaps in our understanding of evolutionary processes in the ocean. The universe heard me, and today I am satisfied to write about the published genome of Euprymna scolopes – the Hawaiian bobtail squid and … Continue reading

Found in translation: The evolutionary history of RNA viruses in vertebrates

I have to admit, viruses aren’t normally my thing, but this is pretty darn cool. In a study out by Shi and colleagues this week, researchers identified 214 new viruses that, as the authors so succinctly state, reveal “diverse virus-host … Continue reading

Exploring the genomic diversity of tubeworm endosymbionts

Tubeworms are cool. (To be read only in your best (eleventh) Doctor Who voice). Although, depending on how close they are to a hydrothermal vent, they might be more on the hot side….Regardless, if you’re on the fence about how … Continue reading

Genomes are coming: Sequence libraries from the honey bee reflect associated microbial diversity

One of the coolest of reasons that cheap sequencing is nifty, in my opinion, is that it has allowed researchers to study individual eukaryotic organisms, and their associated microbes (their microbiome). Let’s be real, we are in the midst of … Continue reading

When less might be more: The evolution of reduced genomes

The advent of affordable genome sequencing has provided us with a wealth of data. Researchers have sequenced everything from Escherichia coli (4.6 Mbp genome size), to sea urchins (810 Mbp), chimpanzees (3.3 Gbp), and humans (3.2 Gbp). Then there are the … Continue reading

A sponge and its symbionts, using genomics to unravel complex relationships

The ocean is full of interesting organisms and even more fascinating (as well as difficult to tease apart) are the interactions among them. From deep sea giant tube worms, to the adorable bobtail squid, symbioses have a central role, and … Continue reading

Different ways to have sex, yet still be a weed

Baker (1955) noticed that when mates are lacking, the ability to undergo self-fertilization will greatly enhance colonization success. Uniparental reproduction seems to be common in colonizing species, whether it’s from a continent to an oceanic island, during a biological invasion or during range … Continue reading
