A general framework captures the evolutionary routes leading to the formation and progression of tumors.

Ignoring the probability of species variation when reporting observations about biological processes leads to misinterpretation of the experimental data.

A novel pheromone/receptor neuron pair mediates attraction between Drosophila larvae, and evolved differences in pheromone signaling underlie changes in social behavior between drosophilid species.

New complex traits can evolve through the elimination of genes in multiple unrelated pathways, rather than through the creation of new gene functions.

Parallel horizontal gene transfer has spread a bacteriolytic gene family to all domains of life, and has bestowed a niche-transcending adaptation in recipients that must deploy antibacterial molecules to survive in a bacterial world.

Reconstructing ancestral enzymes has revealed that a switch in kinase substrate preference evolved via an expanded specificity intermediate that is tolerated in vivo, thus providing a path for kinase diversification.

A general method for inferring fitness from a sample of nucleotide sequences can predict the progenitor of next year's seasonal influenza.
