The human experience has been a long transition for the early humans. At each time period, humans progress and continue the human family alive through the advancement they made. The first humans went through the following periods: Dry Bones (5 million to 2.6 million), Paleothic (2.6 million to 10,000 B.C), Neolithic (10,000 to 4,000 B.C), and River Valley Civilization periods (4,000 B.C to 750 B.C.). Each time period contributed to the human experience. The most difficult to learn about the human experience has been the first stage for various reasons. The beginning of the human family is hard to understand because it was a time that was pre-history. There was no written records because humans didn’t develop as of yet. The only evidence…show more content… Humans shifted from a nomadic to a sedentary lifestyle. People stayed at one location and began developing small communities. It was the time of the first civilizations to emerge. The most important reason humans changed to sedentary life was the emergence of agriculture. Agriculture made it possible to stay in one area because they can make their own the food through agriculture. The introduction of agriculture is the biggest difference between the Neolithic and Paleothic because it shifted the lifestyle from nomadic to sedentary. At first, women knew more about agriculture and making them in charge of agriculture for some time. Now living in sedentary lifestyle, the humans started to build small communities around the base of agriculture. At the same time, humans began to domesticate animals such as sheep, goats, cattle, and pig. From these animals they could get meats, wool, cotton, and other materials form the animals. The need to hunting began to decline since the animals were now living with them in their small villages. The introduction of trade was important because it was time that humans can interact with one another and spread ideas from far away lands. The second difference between the Neolithic and Paleothic age is humans in this period (Neolithic) began to own property and were able to support themselves without the need of…show more content… The civilizations of Mesopotamia, Egypt, and other river valley civilizations thrived by staying near a large waters source for their survivals; moreover, began around 4,000 B.C. with the Mesopotamian. Egypt had the Nile River and Mesopotamia had the Euphrates and Tigris River as their water source. They used the rivers as irrigation systems to water their fields. Communities started to be ruled under a formal government or monarchy. Once small communities began to form into kingdoms due to the usage of armies to conquer neighbors. Egypt and Mesopotamia went to war for slaves that can be used to work on their farming fields. Without slaves to work on the fields would make it difficult to provide food to the kingdom. The kings of these kingdoms were viewed as a messenger of the gods to the people. Religion became important since the ruler was sacred of having a connection to the gods they praised. Both of Egypt and Mesopotamia practiced polytheistic religion since there was a god for everything in a sense. Trade became bigger because Egypt and Mesopotamia traded into a local to inter-regional. There was more interaction and more trading among humans. Mesopotamia is credited of having the first constitution in human history. It was under King Hammurabi (reign 1792 B.C. to 1750 B.C.) that the codes were introduced to Mesopotamia. Some codes include that soldiers were sent
