Metabolomics data reveals unique metabolic insights into how cavefish adapt to nutrient limited environments while staying healthy.

A new tracking method revealed the social-like interactions in the Mexican blind cavefish, which was thought to be evolutionarily lost, and also demonstrated its mammal-like antagonistic association between the social-like interaction and repetitive behavior.

The identification of evolutionarily-derived changes in Hypocretin function within the brains of short-sleeping Mexican cavefish provides a system for investigating the mechanistic basis of sleep differences throughout the animal kingdom.

Astyanax mexicanus surface-dwelling fish exposed to complete darkness develop many traits resembling cavefish adaptations by phenotypic plasticity in a single generation.

Both gill musculature and the evolutionarily conserved cucullaris muscle are derived from unsegmented mesoderm adjacent to the first 3 somites, extending the posterior limit of cranial mesoderm.

Ancient maize (~6700-5000 BP) from Paredones, Peru, originated in Mesoamerica, suffered a rapid domestication process, and fast coastal migration to Peru, involving adaptation to both Mesoamerican and South American lowlands with no relevant introgression from teosinte mexicana.

Phenotypic evolution can originate from variations in very precocious developmental events, starting even before fecundation, during the fabrication of the egg in the mother's gonad.

Genome sequence data from 58 Mexican swine influenza A viruses resolves the spatial origin of the virus that originated the influenza pandemic of 2009.

Genetic analyses reveal that neuroanatomical areas that are developmentally related co-evolve with one another.
