The correct answer is Lewis Henry Morgan
Recognized as one of the founders of modern scientific anthropology, Lewis Henry Morgan was the first to study kinship systems and devised an ambitious theory about man's cultural evolution.
Morgan developed a general theory of the cultural evolution of society, which would take place in three stages: savagery, barbarism and civilization, each marked by the predominance of certain techniques and institutions. The acquisition of a new technique or capacity would mark the end of one stage and the beginning of the next. Thus, the invention of ceramics started barbarism, and writing, civilization.
Although Morgan's theories have revealed themselves over time to be excessively linear and incomplete, his proposal of direct examination of primitive communities and the integration of different cultural, economic and historical factors lent anthropology rigor.
The variable that a scientist observes to change while conducting an experiment is called the responding variable
.
The responding variable (also called dependent variable) is the variable that a scientist observes to change while conducting a scientific experiment. The responding variable depends on the independent variable (also called manipulated variable). When the independent variable is changed by the scientist, its effect on the responding variable is usually observed and recorded. Responding variables can be observed (such as taste) or measured (such as length) in an experiment.
Social stratification created a huge drift in the Roman society.
Explanation:
Roman people never equal social strata. some were inferior while some were superior. Social categories were based on money, power and authority. An upper class Roman child may enjoy all comforts but the lower class Roman child will satisfy its hunger by eating bread made of cheap flour. Plebeians were common people in Rome. Kids of Plebeians never went to school and the women had no rights in ancient Rome.
Patricians are people who belonged to noble family. Kids of Patricians went to school. They were taught by their parents or an educated slave, The poor worked very hard to make both ends meet. Another very important part was a trip to the baths, even on holy days, but the baths were only for Patricians.
