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.
The <span>Upwelling is caused by southerly winds that blow over the ocean surface near the Peru coastline.
The wind causes the water to move and replace the water on the top surface with the water from the deeper surface, creating a change in both temperature and nutrient composition of the water.</span>
Answer:
It's saying use google so use online world maps
Explanation:
Answer:The message should achieve its intended effect
Explanation:This message did not achieve it intended effect because most students did not study at all or did not focus on the correct material. This may mean that they might have been a miscommunication or the message didn't reach most students.
Communication competence refers to
how effective and appropriate the message is and how adaptive it can be.
Mid latitude is the middle latitude
