Answer:
This suggestion best illustrates D. an evolutionary perspective.
Explanation:
The evolutionary perspective seeks explanations for behaviors taking into consideration our species need to adapt and reproduce. From this perspective, our behaviors result from problems our ancestors encountered over 10,000 years ago. Since the purpose of the species is to perpetuate itself, many of our behaviors could be explained by the instinct of reproduction. We look for good mates in order to procreate. That perspective would, therefore, explain men who marry younger women as a result of our reproductive needs - young means fertile, at least instinctively.
Africa has a population of roughly 1.02 billion[3] and a surface of 30,221,532 km². Industrialization started marginally in the early 20th century in the colonies of the European nations, namely Portugal, Belgium, Spain, the Netherlands, Germany, France, Italy, and the United Kingdom. The continent's various wars for independence brought on the violent and disruptive division of Africa. Africa, being a major source of raw materials, saw the colonial powers vie for influence among the newly independent nations, with former colonial powers establishing special relations with their former colonies, often by offering economic aid and alliances for access to the vast resources of their former territories.
Today, the presence of diamonds, gold, silver, uranium, cobalt and large oil reserves have brought Africa to the forefront of industrial development, with many of the world's economic powers building relations with Africa's resource rich nations.
As of 2008, the entire GDP of Africa is about $1.2 trillion.<span>[2]</span>
