Microfossils reported from Archaean BIFs most likely were liposome-like protocells, which had evolved intracellular mechanisms for energy conservation but not for regulating cell morphology and replication.

Vertical locomotion in arboreal mammals is shaped by a complex interplay of body mass, limb proportions, grasping abilities, and head mass, and primates use distinct upright postures during descents.
Centralized migration accelerates adaptation and drives parallel evolution, emphasizing the key influence of spatial organization on evolutionary dynamics across systems from pathogen transmission to species range shifts.

Claims for a Triassic-aged crown lizard merit detailed reanalysis, the results of which find that Cryptovaranoides is not only not a lizard, but is a more distantly related diapsid reptile.
Up-to-date computational pipeline characterizes G-protein-coupled receptor (GPCR) repertoires in the closest relatives of metazoans, providing a framework to investigate the evolutionary origins and ancestral functions of key metazoan signaling pathways.
