Our latest paper revisits Haldane 1957 on speed limits to adaptation, the paper that triggered neutral theory. We clarify and then significantly extend the theory, and apply the resulting model to

Substitution load revisited: a high proportion of deaths can be selective
Abstract. Haldane's Dilemma refers to the concern that the need for many “selective deaths” to complete a substitution (i.e. selective sweep) creates a spe

There are even more direct cuts — because Haskell is run through the federal Bureau of Indian Education, 30% of staff and faculty were let go last night.

Our latest paper

shows that mass PCR testing could control a range of potential respiratory pandemics at low societal cost. We also explore logistics. Even a prototype would be really nice now with H5N1.

We found high levels of adaptive evolution in genes expressed in barrier tissue immune cells including 🫁, and/or expressed early during immune responses --> host adaptation likely works best when it cuts infections short early, before pathogens reach high numbers.

Our new preprint changes the way we look at an “extinction vortex” in which a small population loses fitness, causing it to become even smaller.

Extinction vortices are driven more by a shortage of beneficial mutations than by deleterious mutation accumulation
Natural populations are increasingly at risk of extinction due to climate change and habitat loss and fragmentation. The long-term viability of small populations can be threatened by an extinction vor...
