Novel genomics insights into the molecular evolution of long-distance migratory mammals.

ABSTRACT:

Background

Understanding the genetic basis of long-distance migration in mammals provides important insights into the evolutionary mechanisms that enable species to adapt to changing environments. Despite its ecological significance, the molecular factors underlying this complex trait remain poorly understood.

Results

Our analyses reveal distinct evolutionary signatures associated with long-distance migration in mammals. Through comparative genomics analyses of representative mammalian genomes, we identified multiple genes under positive selection, exhibiting accelerated evolutionary rates, or showing significant correlation with long-distance migration. These genes are predominantly involved in functions related to memory, sensory perception, and locomotor abilities. Additi
