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.
While Mesopotamia and Egypt were two primitive societies, one thing that helped them were their interaction. These interactions help the societies develop faster and thrive. If these primitive societies had more interaction with neighbors, they could copy/imitate technological advances and or culture. Also, there would be more competition and war. Finally, societies with only one or two resources could trade for a bigger variety of resources.
How much is the county is worth.
This is actually the unit I am on right now. These interest will see to that their wants and needs are put into the policy. Brainliest please.
