6. Human Biology



Scientists believe that humans evolved from a primate that lived about 2 million years ago. The humans who have developed since that time have a number of unique characteristics. The most important is the brain. The human brain is the most complex biological structure known to exist in any organism.

Over the last 700 years, researches have learned a great deal about the human body works. Scientists have identified the dozens of types of cells that form tissues and organs and they have learned how groups of organs work together as systems to sustain life. In recent years scientists have even found ways to improve and prolong the lives of humans by using transplanted and artificial organs to replace those body parts that are diseased or injured.
