Population genomics finds veritas in the demographic history of vino

One of the more, hah, fruitful applications of genomic data has been in crop and livestock improvement. Biologists know that domesticating plants and animals for human use has involved powerful artificial selection — usually inadvertent at first, then intensive and … Continue reading

We have the technology. Is sequencing getting better, smaller, faster?

Okay, I know some version of the phrase “recent developments in rapid and affordable sequencing have made blah blah blah possible…” is something you’ve probably read 10,000 times. However, third-generation sequencing platforms have turned out to be pretty darn astounding. … Continue reading

Experimental harvesting reduces gene expression variation

Human activities represent unique selective pressures for natural populations. This is especially true for fish species where we routinely harvest individuals from the wild, i.e., through fishing. It has been recognized for some time that overfishing can result in population … Continue reading

Non-model organisms are so hot right now

What makes a model organism? Well, as the name suggests, they are widely studied and have been adapted to a vast array of common genetic techniques. A few of the most often utilized organisms, which you are most likely already … Continue reading

The largest mammalian genome is not polyploid

Some 40 million years ago in South America, following the arrival of the common ancestor of caviomorph rodents from the Old World, big changes were afoot. Specifically, the caviomorph colonists were beginning to give rise to an extant evolutionary progeny … 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
