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 …

Haploid-diploidy, a (brief?) history

Haploid-diploid life cycles are not only good exercise for the brain, but they’re also fantastic study systems to investigate a myriad of questions. Yet, the majority of molecular studies have focused on the diploid-dominated life cycles of animal and plant … Continue reading

sedaDNA sleuths: embracing your inner Sherlock

Awhile back fellow TME contributor Rob Denton posted about a recent review on environmental DNA by Pedersen et al. (2015). Environmental DNA (eDNA) is obtained from samples such as sediments, ice or water and can provide scientific sleuths with tantalizing clues about past … Continue reading

From cats to rats: two studies on domestication and tameness

Anyone who has ever read Charles Darwin is acutely aware of his fascination with domestication – particularly how he fancied fancy pigeons. Darwin drew on his domestication obsession while writing his book, The Variation of Animals and Plants under Domestication, … Continue reading

Domesticated genes gone wild

Artificial selection of domesticated plants and animals has been cited as a test case for natural selection since Charles Darwin first conceived the latter concept. But we generally consider that these two forms of selection operate to very different ends—that … Continue reading

In the holiday spirit

It’s that time of year again, where conifers across the globe are chopped down and taken into people’s homes or workplaces in celebration of Christmas. According to the IUFRO (International Organizations of Forest Organizations), over 80 million trees are consumed … Continue reading
