The tramanon has evolved through adaptation and mutation to thrive as an omnivore in marshland environments. A likely genetic bottleneck increased the impact of beneficial mutations, such as sharper teeth for eating both plants and small prey (Smithsonian Institution, 2019). Webbed feet and a streamlined tail emerged to improve swimming, enhancing overall fitness and survival in water-rich habitats (National Park Service, 2020). Sexual selection may have reinforced traits like stronger limbs and agility, leading to a more versatile species well-adapted to its changing ecosystem (U.S. Fish and Wildlife Service, 2021). See more
