From this basic assumption, we can derive metrics for the expected covariance among PAIRS of lineages. In effect, we convert a standard phylogenetic covariance matrix into a lineage-pair covariance matrix -- and we can use this to account for non-independence in comp. studies of lineage-pair traits

We start by considering the following tree. Six lineage-pairs can be derived from this tree, three of which are AB, AC, and AD. We ask: of those three pairs, would we expect any two to be more similar to each other than either is to the third in some continuous lineage-pair trait?

RIP Jane Goodall. There's of course no better way to understand Goodall than in her own words, of which there are volumes to explore. But I also love Stephen Jay Gould's introduction to her "In the Shadow of Man": archive.org/details/insh.... As Gould notes, and Goodall embodied, "Nature IS context"

A text box from our Ecology Letters paper on character displacement as a process or pattern
Spoiler: it's explicitly defined as both in the literature, so all we can do is be clear about the particular definition we're using

Fun news to share: I'll be heading to Atlanta in the new year to start my lab at the School of Biological Sciences at Georgia Tech! My group will study the ecological, genetic, and genomic processes that promote the origin of new species and prevent their collapse, thereby building biodiversity.

Spotted at my local barber shop: a 1977 Time Magazine article on the still-raging sociobiology wars. Lol the comics
