How Did Some Stickleback Populations Come To Live Exclusively In Fresh Water

How Did Some Stickleback Populations Come To Live Exclusively In Fresh Water. How did some stickleback populations come to live exclusively in fresh water? How did ancestral populations of ocean-dwelling fish come to live in freshwater lakes?

Some of these are in salt-water lochs, others in fresh-water lochs. The loss of stickleback pelvic spines is similar to the loss of which body parts in some other four-legged. Even though water eventually returns to Earth through the water cycle, it's not always returned to the same spot, or in the same quantity and quality.

How did some stickleback populations come to live exclusively in fresh water?

The stickleback populations in Bear Paw Lake and Frog Lake are both freshwater populations; thus When sea-run stickleback colonized freshwater lakes, some of the populations changed We know that Bear Paw Lake has different predators from the ocean. Researchers think that stickleback populations became trapped in these lakes and adapted to living exclusively in fresh water. The threespine stickleback is a model system for understanding adaptation and ecological diversification.

Some of these are in salt-water lochs, others in fresh-water lochs.

The population of water snails, tadpoles, and stickleback would become higher because the water beetles would not be eating them. How do multiple lines of evidence (from the field, the fossil record, and molecular genetics) work together to illustrate stickleback evolution? In addition, fresh water is not.
