HUMAN BEING

Human being has the most highly developed brain of any animal. The human brain gives people many special abilities, the most outstanding of which is the ability to speak. Language has enabled human beings to develop culture, which consists of ways of behaving and thinking. These ways are
passed on from generation to generation through learning. Culture also includes technology--that is, the tools and techniques invented by people to help satisfy their needs and desires. The richness and complexity of human culture distinguish human beings from all other animals.

The human brain helps make people the most adaptable of all creatures. They behave with the most flexibility and in the greatest variety of ways. The human body is highly adaptable because it has few specialized features that could limit its activities. In contrast, a seal has a body streamlined for swimming, but it has difficulty moving about on land. People cannot swim as well as a seal, but they can also walk, run, and climb. Human adaptability enables people to live in an extremely wide variety of environments--from the tropics to the Arctic.

People are inquisitive and have long sought to understand themselves and their place in the world. Throughout much of human existence, religion has helped provide such understanding. All societies have assumed one or more gods influence their lives and are responsible for their existence. Since ancient times, philosophy (the study of truth and knowledge) has also provided definitions of what it means to be human.

Today, religion and philosophy remain important parts of people's efforts to understand the nature of human existence. But many other fields of study also help human beings learn about themselves. For example, anthropology is the study of human cultures and of human physical and cultural
development. Linguistics is the scientific study of language. Specialists in psychology study human and animal behavior and mental processes. Sociology deals with the groups and institutions that make up human societies, and history is the study of past human events.

Prehistoric people are human beings who lived before writing was invented about 5,500 years ago. Writing enabled people to record information they wished to save, including descriptions of events in their lives. In this way, the invention of writing marked the beginning of history. The period before human beings learned to write is called prehistory, and people who lived during this period are known as prehistoric people.

Most scientists believe the first human beings lived about 2 million years ago. But early people probably arose from prehuman ancestors who first lived more than 4 million years ago. These ancestors were small, humanlike creatures who walked erect. This article will discuss both prehistoric people and their near ancestors. Scientists first discovered evidence of prehistoric people during the mid-1800's. Most of this evidence consisted of ancient, sharp-edged tools that prehistoric people had made of stone. The first fossilized bones of prehistoric people were also found during this time. As scientists collected more fossils of prehistoric people, they began to form a clearer picture of what these early people looked like. For example, scientists learned from fossil evidence that early human beings had smaller brains than most modern people have. This evidence indicated to many scientists that humans had evolved--that is, modified their physical structure over time. Scientists developed a set of ideas about human origins called the theory of human evolution. This theory states that as the environment of the prehistoric world changed, the prehuman ancestors of prehistoric people went through a series of changes that resulted in the first human beings. They, in turn, evolved into modern human beings
