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:
- Imitation
.
- Observational
.
- Modeling.
Explanation:
Learning is demonstrated as the process of enduring change in conduct or behavior that is an outcome of experience and interaction with the external environment.
In the given example, Fatima displays 'imitation', 'observational', and 'modeling' concepts of learning as her behavior of mimicking her mother's behavior(mirror observational learning) exemplify that she learns emulation(exemplify imitation) through observing the environmental factors. <u>While</u> <u>'Modeling' is demonstrated when she learns a particular behavioral change(to feed her doll) through mere observation('of her mother feeding the infant brother') and without any instruction.</u>

Answer:
Bush applied business school management strategies to the administration.
They both attempted to reform the way bureaucracy work
Explanation:
<em>Which statements about the approach that presidents George W. Bush and Bill Clinton took with the bureaucracy are accurate
</em>
<em>The federal civilian workforce has decreased over the last 60 years.(Though there are fewer federal civilian workers, the state and local numbers have gone from 4.3 million to 20 million.)
</em>
<em>-Several recent president have a made a point of campaigning against the size of the federal workforce. (Many recent presidents have claimed to want to reduce the size of the federal bureaucracy, even though few were successful in doing so.)</em>
<em />
Bush applied business school management strategies to the administration.
They both attempted to reform the way bureaucracy work but there strategy is different style.
