This regulatory mechanism is in conjunction with the endocrine system, particularly in the posterior pituitary gland. This is related in the secretion of vasopressin or antidiuretic hormone (ADH). In the event of dehydration or extreme thirst, the body will conserve as much fluid as possible and the posterior pituitary will secrete more ADH that will signal the kidney to reabsorb more water in the collecting tubules.

Answer:
Random chance mutations led to the webbed feet trait in ancestral land birds, conferring them an adaptive advantage. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations.
Explanation:
Mutations are ramdom changes in the nucleotide sequence of the genome of a particular organism. In general, mutations are deleterious, but mutations may occasionally be beneficial in certain environments. A beneficial mutation must be associated with one or more phenotypic traits capable of conferring an adaptive advantage in a certain environment, thereby the individuals carrying the mutation have more chances to reproduce and survive. In this case, one or more beneficial mutations associated with the webbed feet trait passed to the next generations, increasing their frequency in the population.
