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.

apartheid was a very wrong racial idea. Democracy's were important after South Africa banned apartheid in 1991 because they were South Africa's new government.

Answer:
Keegan probably suffered from B. Post traumatic stress disorder.
Explanation:
<em>Post traumatic stress disorder</em> or PTSD is a disorder triggered by a traumatic experience. It is characterized by the exposure to a near death experience or mayor lesion, for example, according to the DSM-5.
Symptoms include intrusion in the form of thoughts which are <em>constant and involuntary</em>, recurrent dreams, dissociative reactions and psychological discomfort, amongst others.
In this case, Keegan was shot and she is having intrusive thoughts about the experience and what it felt like. This is affecting her stress levels, making her angry and jumpy at external stimulus as well as wanting to avoid the scene where it happened.
