THREAT DOWN! Gene flow from polar bears into brown bears
What do you get when you cross a male polar bear with a female brown bear? Trick question: Nothing, because it doesn’t really happen!*
Phonemes and Genomes
Human phonemes and genomes are thought to have evolved hand-in-glove out of Africa. Several recent studies have attempted to capture a picture of this global variation in languages and peoples, often supporting (and rejecting) a serial founder model (eg. see … Continue reading

From crocodiles to coconuts
The first plant trypanosomatids were discovered in plant tissues over 100 years ago, but we know very little about their biology, life cycle or how they have adapted to life inside plants. Jaskowska et al. (2015) provide a review of … Continue reading

Discordance in ancestry inference using human mtDNA and autosomes
Mitochondrial haplotypes have been used extensively over the last few decades for inference of a population structure in humans. Key findings from these studies include what has come to be known as the “Mitochondrial Eve” hypothesis (see the controversial Cann, … Continue reading
Linking gene expression and phenotype in an emerging model organism
Last week in his post “Transcriptomics in the wild (populations),” TME contributor Noah Snyder-Mackler focused on a recent paper by Alvarez et al. that reviews the last decade of transcriptomic research including the goal of linking gene expression and phenotype. Researchers today routinely collect transcriptomic data for non-model … Continue reading
