Temperature-Associated Variation in Evolutionary Rates of FADS1 and FADS2 in Rodents

Abstract excerpt

Environmental temperature is a major ecological factor shaping physiological and molecular evolution in mammals. Fatty acid desaturase genes (FADS1 and FADS2) play essential roles in the biosynthesis of long-chain polyunsaturated fatty acids (PUFAs), which are critical for membrane structure and metabolic regulation. However, their evolutionary responses to climatic variation in wild mammals remain poorly...
