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.
The middle kingdom came to a very sudden end. The Hyksos invaded and took over, and the last Egyptian ruler did not put enough effort into defense of the empire.

Observational methods, case-study methods and survey methods.
Observational Method
With the observational method (sometimes referred to as field observation) animal and human behavior is closely observed. There are two main categories of the observational method — naturalistic observation and laboratory observation.
Case Study Method
Case study research involves an in-depth study of an individual or group of indviduals. Case studies often lead to testable hypotheses and allow us to study rare phenomena. Case studies should not be used to determine cause and effect, and they have limited use for making accurate predictions.
Survey Method
In survey method research, participants answer questions administered through interviews or questionnaires. After participants answer the questions, researchers describe the responses given. In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend.
There are different principles of joint operations. Establishing and maintaining access to operational areas where joint forces are likely to operate is an action in the Shape phase.
The basis of joint warfare is mainly for unity of effort, concentration, initiative, agility, etc. It is very vital to have operational contract support.
The U.S. military's values or system of thought for operations is known to be in a six-phase planning construct. They are;
- Phase 0 (shape)
- Phase I (deter)
- Phase II (seize initiative)
- Phase III (dominate)
- Phase V (enable civil authority)
