A plastic behavior in Escherichia coli is enabled by a single amino acid replacement in adaption to changing environments.

A chemically unstable ostrich eggshell peptide survives for at least 3.8 million years at the equator, stabilized by strong mineral interactions.

Phylogenomics provides support for the Gram-positive type of bacterial cell envelope being a derived character that arose independently multiple times through loss of an ancestral outer membrane.

The extra dimensions in protein sequence space open up indirect paths of adaptation and alleviate the constraint on the selective accessibility to high fitness genotypes.

Despite their extreme morphologies, snakes display a global regulatory strategy of their Hox genes similar to that implemented by mammals with, however, important modifications in enhancer specificity.

Gene flow analysis reveals that the genomes of most sub-Saharan populations are the result of recent historical admixture events.

The ligand specificity and expression profile of the haptoglobin-haemoglobin receptor has diversified throughout the evolution of trypanosomes.

The seemingly simple, constitutive response of the patched/Ptch1 gene to Hedgehog signaling is in fact regulated by large batteries of context-specific Hedgehog-responsive enhancers in both fly and mouse, allowing tissue-specific tuning of the Hedgehog pathway in animal development and evolution.
