Centriole rotational asymmetry, a structural property necessary for cytoskeletal organization in unicellular eukaryotes, is broadly conserved in the centrioles of human cells.
The transcriptional control system of a sea urchin gene reveals the deep evolutionary conservation of a gene regulatory network underlying morphogenesis.

Two putative long noncoding RNAs in zebrafish encode micropeptides with homology to the vertebrate-specific chromatin architectural protein, Hmgn1, which are required for development of vertebrate-specific brain cell types.
Genes associated with age-based division of labor in ants exist in distinct regulatory and evolutionary contexts; genes up-regulated in young nurses are loosely connected and rapidly evolving while genes up-regulated in old foragers are highly connected and conserved.
Integrated phylogenomics and mitochondrial DNA inventory of net-winged beetles across three continents suggest ~1000 undescribed species, biodiversity hot spots, and phylogeny-based classification that sets up the basis for further research.
Finch embryos are laid at an earlier stage than other avian embryos and contain cells with similar properties to pluripotent embryonic stem cells from mice.
Evolutionary analyses suggest that most mammalian circRNAs did not emerge from common ancestral circRNA precursors, arguing against widespread functional conservation.

A new model describes evolutionary transitions in individuality in terms of tradeoff and tradeoff-breaking events as opposed to changes in the nature of fitness.
