New insight into the genetic basis of industrial melanism

The evolution of coloration in peppered moths during the industrial revolution is one of the most well known examples of natural selection in action. Part of the appeal of the system is the apparent simplicity. The once-abundant light colored morph … Continue reading

Microbes are going to infinity and beyond! Monitoring community changes on a simulated space station

As we’ve discussed previously here, understanding microbes in the natural and built environment around us, has implications related to human health and disease. It has turned out to be pretty tricky to clarify what is going on with our most … Continue reading

Mitogenomes from extinct New Zealand wrens shed light on the oldest songbird lineage

The order Passeriformes, commonly known as “perching birds” or “songbirds,” contains over half of all known avian species. Sister to all other Passeriformes are the acanthisittid wrens, a small and enigmatic family of New Zealand endemics. Though their providential phylogenetic … Continue reading

The Great Migration and African-American Genomic History

Over 45 million African-Americans share a recent common history largely shaped by “The Great Migration” (1910-1970) from out of the Southern United States. And yet, the admixture history of the African-American community, and its consequences for public health are little … Continue reading

The not so singular process of hybridization

What, if anything, are hybrids? Zach Gompert and Alex Buerkle ask this question in a special issue in Evolutionary Applications. Hybrids occur when unrelated individuals mate, but how distant do the taxa need to be to constitute a cross? The varied … Continue reading

Data, data everywhere and another tool to use: Taxonomer, a web-tool for metagenomics data analysis

Because sequencing. With all the affordable genome and metagenome sequencing available, we’ve reached an unprecedented point at which we can profile microbial communities more accurately than ever before. For this reason, it’s essential to develop efficient methods for data analysis. … Continue reading

Steelhead in a random forest: identifying the genetic basis of migration

Genome-wide association studies (GWAS) have been quite successful in identifying variants associated with various phenotypes (I suppose there is some debate surrounding this statement. For an interesting, if dated, discussion look here). While most of this work was originally conducted … Continue reading
