Inversion of C3 stereochemistry of monoterpenoid indole alkaloids (MIAs) has to occur at some point during their biosynthesis; however, the mechanism has remained unresolved. Here, the authors report an oxidase–reductase enzyme pair encoded within a gene cluster and demonstrate their collaborative role in inverting MIA C3 stereochemistry.

Although live birth evolved repeatedly in other clades, it has not been found in archosauromorphs, the group including modern birds and crocodilians. Here, the authors describe a fossilized pregnantDinocephalosaurusfrom ∼245 million years ago, providing evidence of live birth in archosauromorphs.

Analysis of fossils of the oldest known caecilian provide insights into the origin and morphological and functional evolution of caecilians.

Using palaeohistology and geochemistry, the placental-like life history of a pantodont species 62 million years of age is determined.

This study found E. coli phylogenetic background shapes TEM-1 beta-lactamase expression and co-amoxiclav resistance. Phylogeny alone shifted isolates from susceptible to resistant, stressing a need for lineage-sensitive genotype-phenotype prediction.

Low oxidation state aluminium complexes have gained wide recognition as discrete and versatile 2-electron reductants, but neutral trimeric structures remain elusive. Here the authors report the synthesis and characterization of two neutral Al(I) trimers whose trimeric structure is retained in solution.

New human fossils from Jebel Irhoud (Morocco) document the earliest evolutionary stage of Homo sapiens and display modern conditions of the face and mandible combined with more primative features of the neurocranium.

Hymenoptera is an incredibly diverse order, with numerous behavioral and morphological innovations. Here, the authors compile a time-calibrated Hymenoptera phylogeny and find that secondary transitions to phytophagy, plant feeding, are associated with significant increases in diversification rate in this group.

The fossil record of the reproductive traits of early birds is limited. Here, Bailleul and colleagues describe the Cretaceous enantiornithine bird Avimaia schweitzerae, which preserves an unlaid egg in the abdominal cavity and putative medullary bone.
