As man is a living organisms so the study of biology helps us to understand ourselves and our behavior.For many of you the most interesting part of biology may be the study of yourself; how your body works; how it reacts to diseases; how you resemble or differ from other people such as your sisters,brothers and parents.You will also learn how you and other living things came to be on this Earth,as part of the origin of life and the process of evolution of organisms.The study of man is not complete unless we also make a comparative study of other animals.For example,by studying the working of muscles in a frog,or the digestive,respiratory and nervous system of a mammal such as the rabbit,we can understand much better how such systems work in our own bodies.
By studying plants man has found that certain plants have medicinal value from which he has been able to manufacture drugs (e.g.penicillin and streptomycin) which have proved effective in the treatment of certain diseases.An ever-increasing human population requires more and more food.Food production can be increased by a careful study of plants and soil.Above all,biology helps us to understand ourselves and the world we live in.
Biology is the study of life.Since we are living beings it would be to our advantage to understand it so that we can avoid all the mistakes we are making today.It's like buying a new car and not reading the manual on how to properly care for it.In one or 2 years it begins to break down and fall apart.The only problem with that is we can buy a new car but not a new earth.
