Butler, Ricki Lewis 1,402 solutions How did some ancestral sea stickleback populations come to live exclusively in freshwater?How did some ancestral sea-run stickleback populations come to live exclusively in fresh water? These populations swam to freshwater lakes to spawn and then never returned to the ocean because there were fewer predators in lakes. They became trapped in lakes that formed at the end of the last ice age.
How did stickleback fish adapt to living in freshwater environments?As an evolutionarily diverse species, sticklebacks have undergone genomic inversion, acquired adaptive gene cassettes, and sequenced their whole genomes. The removal of pelvic spines, similar to the hind limbs of four-legged animals, was one adaptation in sticklebacks for a freshwater environment.
How did some stickleback fish became stranded in freshwater lakes?Sticklebacks started out as saltwater fish. As the glaciers of the last Ice Age receded 10,000 years ago, some of these fish swam inland, and many became trapped in lakes left behind by the glacial melt.
How were stickleback fish isolated?Pockets of sticklebacks were isolated by geologic changes at the end of the Ice Age 10,000 years ago, with each newly separated population evolving in response to local ecological conditions.
