The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.
While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.
Answer for PLATO is ; Darwin concluded that if traits in captive pigeons could be selectively passed on to offspring, the selection of traits could also happen in nature.
The correct option is ALDOSTERONE. Angiotensin ll is one of the most potent sodium retaining hormones. It regulates aldosterone release from the adrenal cortex. The aldosterone hormone stimulates sodium re-absorption through mineralocorticoid receptors in the connecting and cortical segments of the collecting tubules.
