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:
What should convince you most is that Donald is seventy years old and he has lost his ability of fluent and accurate conversation ( finds it difficult to remember his last statement, to be able to know what next to say), adding to the fact that his personality has become erratic.
Explanation: Alzheimer's disease is a type of demantia that causes problem with memory,thinking and behavior.
Because he is not only having a loss of memory, but he is also behaving erratically, which is a special attribute of Alzheimer's disease from other demantia disease, that means the doctor is right.
Donald is 70 years old, and Alzheimer's disease is most likely to be seen in people from 65years old upward, it is very convincing that the doctor is right.
IF ALL THIS FACT WAS NOT ABLE TO CONVINCE YOU, DONALD SHOULD GO FOR THE SAME DIAOGNOSES IN ANOTHER HOSPITAL, PERFORMED BY ANOTHER DOCTOR, SO THAT YOU CAN BE CONVINCED IF THE TWO RESULT ARE THE SAME.
Yesterday, for the first time ever, Carson smoked marijuana. according to labeling theory, Carson devoted Primary Deviance. Prominent Sociologist Edwin Lemert gestates leading deviance as engaging in the initial act of deviance. This is very natural throughout society, as everyone takes part in essential form abuse.
