Re‐make, re‐model: evolution and development of vertebrate cranial lateral lines

open access: yesBiological Reviews, EarlyView.
ABSTRACT Lateral lines are placodally derived mechanosensory systems on the heads and trunks of many aquatic vertebrates. There is evidence of lateral lines in the earliest known vertebrate fossils, and they exist in organisms with widely different craniofacial morphologies – including the presence or absence of jaws, external or internal nostrils, and

Separate Determination of Strontium and Barium Mass Fractions in Calcite and Dolomite in Carbonate Rocks by a Multi‐step Sequential Leaching Procedure

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points A ten‐step sequential leaching procedure was applied to dissolve carbonate samples, with 10% of the sample mass dissolved in each step. Calcite dissolves preferentially compared with dolomite. Strontium and barium concentrations released in each step are proportional to the dissolved calcite‐to‐dolomite ratio.

Genome duplications, genomic conflict, and rapid phenotypic evolution characterize the Cretaceous radiation of Fagales

open access: yesJournal of Integrative Plant Biology, EarlyView.
Fagales show “early burst” model of phenotypic disparification, with morphospace being filled during the early radiation of the Fagales crown and its major families. The elevated levels of phenotypic evolution often correspond to hotspots of gene duplication, whereas species diversification is decoupled from both phenotypic and genomic evolution ...

Bipedalism or bipedalisms: The os coxae of StW 573

open access: yesJournal of Anatomy, EarlyView.
There has been a long debate about the possibility of multiple contemporaneous species of Australopithecus in both eastern and southern Africa, potentially exhibiting different forms of bipedal locomotion. Here, we describe the previously unreported morphology of the os coxae in the 3.67 Ma Australopithecus prometheus StW 573 from Sterkfontein Member 2
