Analysis of regional-scale pollen data from southeast Australia that span the entire Holocene epoch reveals that plant functional diversity has been highly variable in time and space. A functional perspective on palaeoecological data helps us to better understand the current climate–biodiversity crisis and to predict future changes.
Comparative analysis of human and macaque brain transcripts together with experiments in mice and in a cortical organoid model show the de novo emergence of a hominoid-specific protein-coding gene implicated in brain development. The evolution of RNA nuclear export signals enabled a new protein to become translated from an ancestral long-noncoding RNA locus.
