The study of Astyanax mexicanus, encompassing both its cave-adapted and surface-dwelling forms, has emerged as a model for understanding evolutionary adaptation to extreme environments. Researchers ...

Researchers have studied gene expression dynamics during metamorphosis in two species of flies. Published in the Genome Biology and Evolution, the study aims to identify patterns of changes in gene ...

The study blends math, statistics and biology to show that this long-held hyperbolic pattern is an anomaly because it doesn't account for the fact that all species on earth are defined as much by ...

Biological functions, resource availability, and evolutionary processes often play a key role in determining the expression of genetic traits and their correlations. In fact, several plant traits are ...

Fisher's mechanism of sexual selection is a fundamental element of evolutionary theory. In it nonrandom mate choice causes a genetic covariance between a male trait and female preference for that ...

A New York University-led research team has used single-cell RNA sequencing technology to compare individual cells across corn, sorghum, and millet, and reveal evolutionary differences among these ...

Fossil records and archaeological findings suggest a correlation between the two, but they do not yet provide definitive proof that the evolution of the brain and hands was directly linked in a ...
