The period of human evolution has coincided with environmental change, including cooling, drying, and wider climate fluctuations over time. How did environmental change shape the evolution of new adaptations, the origin and extinction of early hominin species, and the emergence of our species, Homo sapiens? (‘Hominin’ refers to any bipedal species closely related to humans – that is, on the human divide of the evolutionary tree since human and chimpanzee ancestors branched off from a common ancestor sometime between 6 and 8 million years ago.)
How do we know Earth’s climate has changed? How quickly and how much has climate changed? One important line of evidence is the record of oxygen isotopes through time. This record of δ18O, or oxygen stable isotopes, comes from measuring oxygen in the microscopic skeletons of foraminifera (forams, for short) that lived on the sea floor. This measure can be used as an indicator of changing temperature and glacial ice over time. There are two main trends: an overall decrease in temperature and a larger degree of climate fluctuation over time. The amount of variability in environmental conditions was greater in the later stages of human evolution than in the earlier stages.
Price support will be beneficial to producers but costly to consumers.
Price support refers to efforts by a government to keep the price of a commodity higher than it should be were it priced based on supply and demand.
Ways the government can do this include:
- Subsidies
- Production quotas - limiting the quantity produced
- Price controls
Price supports make prices higher than they should be which would give producers more profit therefore tennis racket producers benefit.
On the other hand, they make things more expensive for consumers who will be forced to spend more than they usually do on tennis rackets thereby making it costly to them.
In conclusion, price controls help producers but are costly to consumers.

In the last decade of the 18th century, both France and England experienced revolutions. In France it was a political revolution against the Old Order, and in England it was an economic revolution that changed the way wealth was produced and shared.
Two main assumptions of functional theory and conflict theory are Social stability, social integration and social class and gender.
<h3>What are the major assumptions of functional and conflict theories?</h3>
- Functionalism: Social stability is key to have a strong society, and adequate socialization and social integration are necessary to achieve social stability.
- Conflict theory: Society is full of pervasive inequality based on social class, gender, and other factors.
<h3>How can each theory be used to understand the North American international auto show held in Detroit each year?</h3>
The theory, functional theory for instance, can be used to understand it by knowing that Society’s social institutions perform important functions to help ensure social stability. The essence of such show is to bring about social stability
Similarly, Conflict theory can help understand that far-reaching social change is needed to reduce or eliminate social inequality and to create an egalitarian society.
Therefore, while functional theory is used to understand the show for social stability, the other theory, conflict theory, us used to bring about social equality.
