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:
<u>Option- </u>True.
- The following statement is correct in all sense, which is given to us as, <em>"According to Matsumoto and Fletcher (1996), culture influences human emotion and human physiology, particularly with respect to autonomic nervous system activity and the immune system."</em>
Explanation:
Culture is defined as the basic set of regional or community rules which are supposed to be followed by the individual living in that space or region, so, culture has a specific role in development of any person's nature, career, and identity inside any region. While, it gives a more different features or we can say characteristics to the individual as it particularly adjusts the person's autonomic nervous system activities and the immune system itself. As we can analyze that people belonging to different cultures have a more or less differently developed physical and mental well being as compared to other individuals of the different cultures.
