This is because they reflect more of the incoming light and their albedo is higher than that of forests or the sea. The structure of the sheet consists of thin horizontal layers of coarse silt and very fine to medium grain sand, separated by layers of coarse sand and pea-gravel which are a single grain thick.
A History of Civilization Harper and Row: Families are usually run by men. Men earn more than women. Sons are preferred over daughters. Men have more options than women.
In many countries women are relegated to the home. In many societies women become adults only through marriage, when they are "given away" by a father to a husband. Even in the United States, after years of feminist efforts, women are often "token" public officials.
Did men always exert power over women? Was there ever a time when women were more powerful than men, or when men and women were equal? Has male power existed throughout history? Is male domination universal, part of human nature?
Has the power of men and women changed over the long course of human history? These are some of the questions asked in this chapter.
We must look at the most basic changes in human history to see how they affected men and women. To do this, historians require the help of archeologists.
This is because historians normally study only written records of human activity, and writing goes back only five thousand years, to the first cities, where writing was invented.
Archeologists dig beneath these ancient cities for the silent records-the pieces of broken pottery and huts, the charred animal remains, the fragments of human bone, the painted shells, the stone axes and digging sticks.
These actual pieces of the past reveal something about the earliest human societies before the invention of writing and city life. An archeological dig resembles a trip back in a time machine.
The further you dig, generally, the earlier the society you find. After a sufficient number of repetitions, archeologists discover in reverse general patterns of human development.
In this way they have distinguished three stages of human development: Archeologists are even able to give approximate dates to these different stages of human development.
Thus, they have determined that the first cities were created about five thousand years ago, and the earliest farming villages go back about ten thousand years. We can summarize all of human history, then, in very rough terms.
First, all humans were hunters of wild animals or gatherers of wild plants and insects. Then, gradually, after B. A third stage of human history began around B. The urban revolution was based on improved agricultural practices, including the use of a plow drawn by animals.
The efficiency of the plow allowed society to become more specialized. Not everyone had to farm to eat. A larger population was also possible.
Cities were both larger and more specialized than agricultural villages. We might even add a recent fourth stage to this outline of history.
In the last two hundred years the world has experienced an industrial revolution that has increased productivity and changed human life every bit as much as the agricultural revolution did ten thousand years ago and the urban revolution did five thousand years ago.
It is safe to say that no changes in human history have been as important as these. Obviously, not all hunters, or an farmers, are alike. But the differences between hunters and farmers are much greater than the differences between any two groups of either.
And while there are still farmers in city societies since people have to eatthe lives of these farmers have been transformed by city markets, governments, tools, culture, and communications. Farmers today are very different people from those who lived before the development of the first cities five thousand years ago.
If the power of men is universal, then, we should expect it to have remained relatively constant from hunting to farming to city society. These separate assignments go far beyond what is required by the differences in size or strength between men and women or the need of women to carry and nurse infants.
In fact, some jobs are thought of as "masculine" in one society and "feminine" in another. There are certain generalizations, however, that are almost universal among hunters and gatherers.Men and Women, Hunters and Gatherers excerpted in its entirety from Kevin Reilly's The West and the World: A History of Civilization (Harper and Row: ).
