Sparrows and spiders and aggression, oh my!
One of the major goals of evolutionary biology is to link phenotypic variation with specific genetic variation, yet for behavioral phenotypes in non-model species, this task remains daunting and generally elusive. Although behaviors are heritable and clearly acted upon by … Continue reading →

How many samples do you need to investigate relationships between genetic make-up & immune function?
When an organism is exposed to a pathogen, what determines their ability to resist or recover from infection? Mounting an effective immune response is a complex dance with multiple partners, changing tempos, and maybe even a costume change or two: … 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 →

Earth BioGenome: The launch of biology’s moonshot
The Earth BioGenome Project aims to sequence all currently described ~1.5 million eukaryotic species on earth (Lewin et al., 2018; Figure 1). The scale and scope are enormous, and it is hard to imagine a more ambitious but exciting goal. … Continue reading →
Evolution 2018: assortative mating, combinatorial speciation and genome dynamics
The Evolution conference in Montpellier is over, and as the sun, wine and great science become a memory, here is my recap of some conference highlights following on from a great first day: Sharon Strauss (University of California Davis) gave … Continue reading →

The eyes have it!
Eyes are pretty darn complicated, which makes them cool models for studying complex trait evolution. Maybe the first time I realized how interesting eyes are when I saw this by the oatmeal about the amazing-ness of the mantis shrimp (are they your … Continue reading →

Metabarcoding for every body, every habitat, every time
The immediate reason why I wanted to write about Boosting DNA metabarcoding for biomonitoring with phylogenetic estimation of operational taxonomic units’ ecological profiles is its usefulness for the scientific community and the effort of the authors to make their study reproducible. … Continue reading →

What is DAS? A new tool to recover genomes from metagenomes
There are a lot of data out there, and if you haven’t already noticed the ‘omics train has steadily stayed its path through the fruitful (but challenging) world of metagenomics. Metagenomics offers the chance to unravel complex microbial communities without … Continue reading →
Chromosomal inversions and the maintenance of species barriers
Chromosomal inversions have long fascinated evolutionary biologists for their role in adaptation and speciation. These structural variants are abundant in natural populations and can have diverse evolutionary consequences. They can cause reproductive isolation through hybrid sterility or protect sets of … Continue reading →
