[edit] Study of the human body

Some people study the human body. They look at where it is different from or the same as other animals' bodies. These animals can be alive today. Or they can be extinct animals like other hominids. (Hominids are primates that are close to humans. Neanderthals and Homo erectus were hominids.) Some people study how the human body works and lives in its environment. Some people study what people think about their body. Artists study how to draw or paint the human body.

[edit] Fields of study

Many different fields of study look at the human body.

• Biology is a field of science. It studies living things. It looks at how the human body works. It studies how the human body came from evolution. It studies how genetics makes the human body.
• Ecology is a field of science. It studies how the human body senses its environment. It also studies how humans affect the environment. These actions include using natural resources. These actions include making waste.
• Anthropology is a field of science. It compares humans to other hominids. It also studies all other hominid bodies. They look at how humans and chimpanzees are the same or different.
• Psychology is a field of medicine. It looks at how people think and feel. The brain is part of the body. How we think and feel comes from the brain. So psychologists study the body. They study how the brain lets us be who we are.
• Religion also talks about the body. Some religions see the body as where the soul lives. Some see the body as like a church. This is because a church is where people worship God. These people think God should be worshiped inside people. Some religions think the body is made from chakras that connect us to the universe.
• Medicine sees the body like a machine. Doctors want to fix problems with the body. They study how to fix the problems, called diseases

[edit] The human body and other animals

Scientists think that the human body is very much like other animals. They see that some human behaviors are like animal behaviors. (Behaviors are the way an organism acts.) The know that 98% of the DNA in humans is the same as other primates.

The animal that is alive now that is closest to humans is the chimpanzee. 98.4% of the DNA is the same between humans and chimpanzees.
