To the final estuaries

For the final stop on our Japanese sampling leg, we ventured to the most populous metropolitan area in the world. Tokyo was known as Edo (江戸), or estuary, until it became the imperial capital in 1868. An apt location to end our field expedition … Continue reading

Genomics of domestication in chicken and cattle

Two recent studies attempt to understand the process of adaptive evolution in domestication and artificial selection by characterizing (a) sweeps, and their association with phenotypes in extant hybrid lines (Sheng et al. 2015), and (b) phylogenomic position of an extinct … Continue reading

Small mammalian genomics of adaptation

While large mammals have had their day on our blog, two recent studies on small mammals reveal the genetics of size evolution in island mice, and differential introgression of mitochondrial and nuclear genomes in chipmunks – steps towards understanding the … Continue reading

The unforeseen genomic consequences of domestication

When a desired genome is selected for propagation, all mutations, beneficial, neutral, or deleterious, shift in frequency, and this sometimes can have unforeseen consequences. Natural selection takes the good with the bad. Beneficial and harmful mutations combine to provide a net … Continue reading

Where’s your wine from?

Human-mediated selection of yeast cultures has played a huge role in the development of numerous unique strains of Sacchromyces cerevisiae, often attributed to production of a wide variety of wines the world over. Previous studies have indicated a single domesticated … Continue reading

Clonal conundrum, part deux

In the second installment of the clonal conundrum, one hallmark of clonality is one that surprisingly hasn’t been validated that many times using species that have both sexually and asexually reproducing populations. Theoretically, clonal reproduction should generate massive … Heterozygote excess … Continue reading

Clonal conundrum, part un

Molecular ecologists are faced with a clonal conundrum when we wish to investigate the evolutionary ecology of clonal organisms. An attack of the clones is not something that should frighten one away …
