Functional genomics reveal complex genome regulation during the coenocytic development of the ichthyosporean Creolimax fragrantissima, a protist closely related to animals.

Experimentally reconstructing the evolution of the molecular complex that animals use to orient the mitotic spindle establishes a simple genetic and physical mechanism for the emergence of a function essential for multicellularity.

A long-term evolution experiment with Escherichia coli shows that the appearance and optimization of a new trait can require both co-opting existing cellular pathways for new roles and reversing a history of previous adaptation.

Fish trace amine-associated receptors evolved a novel structural motif that enables the detection of chemically diverse amine odors in a non-canonical 'inverted' orientation.
Deletion of one gene can lead to inactivation of other genes which restore a perturbed cellular function but change the epistatic interactions and the dynamics of the responsible module.
A new method of protein structure prediction that incorporates residue–residue co-evolution information into the Rosetta structure prediction program was used to develop models for 58 large protein families that had no previous structural information.
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.
