Biological adaptation is the evolutionary process through which heritable traits that enhance an organism’s fitness become more prevalent in a population over generations under specific environmental conditions. It operates primarily via natural selection acting on genetic variation, including mutations, recombination, and gene flow, and is constrained by developmental, genetic, and phylogenetic factors. Adaptations can be morphological, physiological, or behavioral and are typically characterized by increased survival or reproductive success in a given niche. The process is dynamic and context-dependent, such that traits advantageous in one environment may be neutral or deleterious in another, contributing to diversification and speciation.
Many fish appear to hang effortlessly in the water while they wait for prey, defend a nest or pause between bursts of activity. But our research shows that this quiet stillness is anything but effortless. Hovering, the behavior ...

In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels—such as those found at high altitudes. One of the most striking observations from that ...

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its limits. In a perspective ...
