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.
Answer:
yes?
Explanation:
One could say that a black man being elected president could be liberation for the civil rights movement. African Americans finally having the opportunity to be seen in public office. Their opinions and beliefs being valued at a presidential level just the same as a white man. The civil rights movement was a movement for African Americans to have equal rights and opportunities as non African Americans. I'm sure Barack Obama being president could uplift the minority since they have been working fruitlessly for that opportunity. An opportunity that is but a human right for African Americans to have equal opportunity in their country.

<span>The answer is Peter Berger's concept of debunking. It means to expose the falseness. Peter Berger is a author of Social Construction. Humanity is the main one in the sociology and it place the discipline close to the humanities like literature, history and philosophy etc. Based on humanity the unmasking assumptions are debunking.</span>

"The poor depended on grains to survive while the wealthy enjoyed game and other exotic dishes" is the best comparison for the food available to the poor versus that which the wealthy enjoyed.
<u>Explanation:</u>
The difference of food consumed by rich and poor depends upon the specific countries but two assumptions are common among all nations that rich consume their food in more pieces and in more fancy manner than poor. Here if we discuss Romans than following could be understood:
- On an average the Rich Romans ate three meals, first meal/breakfast was called the "ientaculum". It was usually eaten around dawn, involve bread and perhaps some fruit.
- The lunch meal was called the "prandium" it was a very small meal, consumed at about 11 AM.
- The "cena" was the major meal of the day it was consumed in the afternoon.
- A porridge name, "puls," was the staple food of the poor. Puls was made by combining ground wheat and water. They might sometimes get some vegetables or fruits to consume with their pulses. Meat was consumed very rarely by them.
Answer:
Most cases that deal with federal questions or offenses begin in district courts, which are almost always granted original jurisdiction. District courts hear appeals cases only in the rare case of a constitutional question that may arise in state courts.
