Biologist studying mammalian phylogeny, morphology, comparative biology, and macroevolution.

The largest mammalian genome is not polyploid

Some 40 million years ago in South America, following the arrival of the common ancestor of caviomorph rodents from the Old World, big changes were afoot. Specifically, the caviomorph colonists were beginning to give rise to an extant evolutionary progeny … 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

A Comparative View of Comparative Phylogeography

A recent issue of PNAS includes papers from a Sackler Colloquium on comparative phylogeography. As stated by the organizers, a major purpose of that gathering “was to bring together leading scientists to address the current state of phylogeography as the … Continue reading

The Genomics of Rapid Adaptation

Phenology (the timing of life cycle events such as growth, breeding, or migration) is among the most sensitive organismal traits to climate and environmental change. In recent years, phenological shifts have been documented in numerous taxa, in traits such as … Continue reading

How do Missing Data Impact Phylogenetic Inference with UCEs?

Next-generation sequencing (NGS) has put gobs of sequence data in the hands of molecular biologists, and that data is measurably advancing our prospects for a fully resolved Tree of Life. Nearly simultaneously, however, we have realized that every NGS dataset … Continue reading

Greetings from Austin, with a look towards Evolution 2016.

As the yearly conference season approaches full swing, the minds of many evolution-oriented scientists turn, naturally, to Evolution. The Evolution conference is the annual conclave of three of the discipline’s foremost societies (American Society of Naturalists, Society for the Study … Continue reading
