Humans are mediocre sprinters, but in 36–41°C heat researchers watched a hunter pursue an oryx until the animal's body reached 44°C while his own stayed below 39°C — a glimpse of an endurance advantage our genus may have begun evolving roughly 2 million years ago scienceblog.com/t-human-endu…

A Namib field study recorded an oryx at 44°C while one instrumented hunter maintained thermal control. The result supports feasibility, not proof that persistence hunting drove human evolution.

A new article argues that a new C. dilepis complex species is invalid under ICZN rules, the description does not uphold the claims made to define the new species, & that elevation of additional subspecies to species status are premature. tandfonline.com/doi/full/10.…

Whole‐Genome Data to Investigate Recent and Historical Dog Introgression Patterns in Italian Wolves

We analyzed whole-genome data from Italian wolves and dogs to assess the extent, timing, and functional relevance of dog introgression in the Italian wolf. Five wolves showed recent admixture within...

Just in time before Christmas 🎅🏻🧬 Very happy to share this work, where we identified several horizontal gene transfers between fishes. This is a first for vertebrates (except for the anti-freeze protein example) ! biorxiv.org/content/10.1101/…

Strong evidence for multiple horizontal transfers of immune genes between teleost fishes

Horizontal gene transfer (HGT) is less frequent in eukaryotes than in prokaryotes, yet can have strong functional implications and was proposed as causal factor for major adaptations in several...
