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.
In my honest opinion, I think that the Chinese government has no right to block off the rights to social media and possibly the internet. The internet is how we all connect to each other, see friends, learn about the world, basically get smarter and more aware. If the Chinese government takes away the right to the internet, the literacy rate will drastically drop, and business will slow down. China won't be considered a world super-power anymore, and American companies will dominate the industry scene instead of Chinese owned businesses. To close, if there is no social media in China, China will face the consequences.

Answer:

Explanation:
The age-related changes that best explain her experience is the lenses in her eye are beginning to yellow. This, yellow lens, leads to absorption and scattering of blue. This absorption and scattering of blue light makes difficult to easily tell the difference between shades of blue, green and violet.
