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.
A new paper in Molecular Biology and Evolution, finds that changes in animal development induced by climate shock persist generations after the initial event. The escalating effects of climate change are likely to, in effect, ...

In most bumblebee species, the queens spend their winters buried underground in a tiny cavity the size of a grape. For six to nine months, they enter a deep sleep-like state called diapause, waiting for spring.
