Answer:

A good example may be represented by different shapes and sizes of beaks in finches living on different Galapagos islands

Explanation:

According to the evolutionary theory proposed by Darwin, natural selection is a mechanism that acts on heritable phenotypic variation among individuals within a population. Genetic variation can be considered as the primary source of heritable phenotypic variation. Those organisms that are better adapted for a particular environment will have more chances to survive and reproduce, thereby passing these heritable traits to the next generation. For example, during his work, Darwin observed that the shape and size of beaks in finch species from different islands in the Galapagos archipelago varied as a consequence, i.e., as an adaptation, to the availability of food resources present in each island.

PtichkaEL [24]

If an individual has an <u>increased</u> rate of blood flow to the skin,such as would happen with emotion or alcohol consumption ,their skin takes on a <u>reddish</u> tinge.

Explanation:

Our skin is provided with a large number of blood capillaries. These capillaries bring blood and nutrients to the layers of skin. Whenever vasodilation of these capillaries occur, the blood flow to the skin increases and the skin gets a reddish tinge.

During an emotional upsurge such as embarrassment causes the adrenal glands to release adrenaline.

Adrenaline as well as alcohol vasodilates the blood vessels and increases the flow of blood to the skin. Hence, the skin gets a reddish tinge.
