Conifer convergence

Convergent local adaptation is typically studied within a species or between closely related species. In these cases, it is perhaps not unexpected to observe parallel evolution due to common genetic variation, constraints, etc. Convergence between species is somewhat less studied, … Continue reading

The tarsier’s nuclear genome comes with a bonus mitochodrial genome

This week Nature Communications published a paper presenting a new genome assembly for Tarsius syrichta, the Phillipine tarsier. Tarsiers are the subject of one of the best of Ze Frank’s “True Facts” videos, and they occupy an interesting place in … Continue reading

The Hidden History of Kiwi Diversification

Of the millions of Earth’s species that likely remain to be described, a majority is thought to be invertebrates, plants, fungi, or microbes. Nevertheless, the pace of species description in some vertebrate groups has not slackened over the past few … Continue reading

Divergence and Linked Background Selection

We have widely discussed the reduction in neutral diversity due to demography and linked selection effects (e.g. selective sweeps and hitchhiking, or background selection) in several previous posts (e.g see here, here, and here). However, how linked selection affects neutral divergence … Continue reading

Building bridges across the chaos

In a new review, Eldon and co-authors (in press) attempt to build a bridge across the chaos of genetic patchiness in the sea. They i) describe the patterns characterized as chaotic genetic patchiness, ii) discuss the potential causes of these patterns and … Continue reading

The almighty CRISPR-Cas9 technology: How does it work?

CRISPR-Cas9 took the whole world of biology by storm. Selected Science’s 2015 Breakthrough of the Year, the CRISPR-Cas9 technology is revolutionizing science. Within five years of the official announcement (Jinek et al. 2012), it became the genome-editing technique of choice. … Continue reading

Is equilibrium out of reach or are there some sneaky bouts of sex?

Reproductive systems impact the evolution of genetic diversity at the population level. Yet, we don’t know a lot about organisms that are partially clonal, despite the large component of biodiversity that dabbles in asexual reproduction to varying degrees. Clonal dynamics are … Continue reading
