Answer:

Disruptive selection

In this example, the type of selection that is expected to occur in the population is disruptive selection.

Trace the origin of the concept of demography.​
Aleks [24]

Answer:

<h2>Demography?</h2>

Historically, such measurements were not carried out for demographic purposes but to assess military strength or the tax base. Frequently, the data were not centralized, making analysis difficult. The registration of births and deaths usually was done for legal purposes such as establishing inheritance rights and was not equally relevant to all parts of society.

Demography is the study of a human population, a definable group of people, and of additions to and subtractions from its number. A population is increased by births and immigration and decreased by deaths and emigration. In a "closed population," there is no migration and attention is paid only to reproduction and mortality.

Eddi Din [679]
Firstly a civil society consists of institutions and organizations that are the reflection of the will of the people of a certain society or a nation. A global civil society functions in a similar way and consists of the similar institutions but it is not just a society of one group of people like one country but all countries. This can be reflected in many ways and not all of them on a political level, as there are individuals who take great efforts to help and give support to others in different countries to deal with various problems such as discrimination and gender inequality.

Which of the following contributed to the spanish taking control of the empire?
irga5000 [103]

Answer:n the European race to colonial dominance, the Treaty of Tordesillas legitimized Spain’s holdings in the New World, indicating Spanish primacy over Portugal.

The successes of Columbus ushered in an era of Spanish conquest that led numerous other European explorers to attempt similar colonization projects.

Spain gained immense wealth from this expansionism, which translated into an influx of Spanish art and cultural capital.

Treaty of Tordesillas

Columbus’s colonization of the Atlantic islands inaugurated an era of aggressive Spanish expansion across the Atlantic. Spanish colonization after Columbus accelerated the rivalry between Spain and Portugal to an unprecedented level. The two powers vied for domination through the acquisition of new lands.

In the 1480s, Pope Sixtus IV had granted Portugal the right to all land south of the Cape Verde islands, leading the Portuguese king to claim that the lands discovered by Columbus belonged to Portugal, not Spain. But in 1493, Spanish-born Pope Alexander VI issued two papal decrees giving legitimacy to Spain’s Atlantic claims over the claims of Portugal. Hoping to salvage Portugal’s holdings, King João II negotiated a treaty with Spain. The Treaty of Tordesillas in 1494 drew a north-to-south line through South America. Spain gained territory west of the line, while Portugal retained the lands east of the line, including the east coast of Brazil.

Conquistadores and Spanish colonization

Columbus’s discovery opened a floodgate of Spanish exploration. Inspired by tales of rivers of gold and timid, malleable native peoples, later Spanish explorers were relentless in their quest for land and gold. Spanish explorers with hopes of conquest in the New World were known as conquistadores. Hernán Cortés arrived on Hispaniola in 1504 and participated in the conquest of the Island. Cortés then led the exploration of the Yucatán Peninsula in hopes of attaining glory.

In 1519, Cortés entered Tenochtitlán, the capital of the Aztec/Mexica Empire. He and his men were astonished by the sophisticated gardens and temples in the city, but they were horrified by the practice of human sacrifice. Above all, the Aztec wealth in gold fascinated the Spanish explorers.

Hoping to gain power over the city, Cortés took Moctezuma, the Aztec ruler, hostage. The Spanish then murdered hundreds of high-ranking Mexica during a religious festival, but the people of Tenochtitlán quickly retaliated. Cortés and his people fled for their lives.

Following his defeat, Cortés slowly created alliances and recruited tens of thousands of native peoples who resented Aztec rule. Only by playing upon the disunity among the diverse groups in the Aztec Empire were the Spanish able to capture Tenochtitlán. In August 1521, Cortés claimed Tenochtitlán for Spain and renamed it Mexico City. The Spanish also brought smallpox, which took a heavy toll on the people in Tenochtitlán. Illness played a much greater role in the city’s downfall than violence.

Cortés was also aided by a Nahua woman called Malintzin—also known as La Malinche or Doña Marina, her Spanish name—whom the natives of Tabasco gave him as tribute. Malintzin translated for Cortés and, whether willingly or under duress, entered into a physical relationship with him. Their son, Martín, may have been the first mestizo—person of mixed indigenous American and European descent. Malintzin remains a controversial figure in the history of the Atlantic World; some people view her as a traitor because she helped Cortés conquer the Aztecs, while others see her as a victim of European expansion. Regardless, without Malintzin’s help, Cortés would not have been able to dismantle the Aztec Empire.

Another conquistador, Francisco Pizarro, made his way to the Spanish Caribbean in 1509, drawn by the promise of wealth and titles. He participated in successful expeditions in Panama before following rumors of Inca wealth to the south. Although his first efforts against the Inca Empire in the 1520s failed, Pizarro captured the Inca emperor Atahualpa in 1532 and executed him soon thereafter. In 1533, Pizarro founded Lima, Peru. Like Cortés, Pizarro had to combat not only the native peoples of the lands he was conquering but also competitors from his own country—a Spanish rival, Diego de Almagro, assassinated him in 1541.

Hernando de Soto had participated in Pizarro’s conquest of the Inca, and from 1539 to 1542, he led his own expeditions to what is today the
