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.
This statement is true: <span>The mineral ores for gold and silver are commonly found in the earth's crust.
These two types of metals are known as native metals because they are naturally occurring within the Earth's stratosphere. These metals are usually found through mining processes because they are often found mixed with sediments and other soil components. One method of acquiring gold is called gold panning while silver is obtained mixed with silver sulfide and sulfosalt minerals.</span>
