Loved this book. Gives one a sense that human progress in understanding the living world is so embedded in culture. Perhaps we’re on the eve of a Buffonian Renaissance.

FIGURE 4 | Estimated mean dates for biogeographic events in Erythrinidae on tectonically active (Western) and passive (Eastern) continental
margins. (A) Phylogenies of species in erythrinid genera from Figure 2A. Numbered circles represent biogeographic events dated using the geological
literature (Table S3). Lettered tip labels represent biogeographic areas on the map. Red numbers at tree nodes represent mean divergence time esti-
mates (Ma). (B) Lineage-age distribution of biogeographic events for clades in Panel A. Estimates are reported for minimum, median and maximum
(mean dates from Figure 1) event age (Table S3). Ages of tectonic uplifts are indicated by horizontal rose bars. Note pulsed-age distribution of bio-
geographic events in clades on the active Western margin, while the more continuous age distribution of events on the passive Eastern margin. Note
opposite directions of watershed migration and geodispersal routes. Fish photographs: Hoplias and Erythrinus (Martin Taylor) and Hoplerythrinus

Very proud of this paper led by @lsu.bsky.social students where we examine what β€˜Unexplored’ means in a natural history context - we recommend β€˜biodiversity blindspots’ instead for places that lack digitized public data

Turns out the Snail Darter, which halted a TVA dam’s construction in the first major test of the Endangered Species Act, was never a distinct species. All species descriptions are hypotheses open to testing.

The "Oxyrhynchus fish" (Mormyrus god fish) itself is worth a visit to the Motor City. Would love to know how many of these there are in U.S. museums.

Low engagement is not the issue. A journalist baselessly called a pedophile and multiple death threats proffered. No consequences. Not off to a promising start.

It probably hasn't been. I'm mostly here for the fish. But when I read the story above my blood boils. Yours doesn't?

I wanted to like you Bluesky, I really did. You're a young platform still finding its legs. But if this is designed to be a "safe space" for people with views far left of center with no viewpoint diversity and you can't shut down murder threats against journalists my time here will be short.
