Importance Of Biology In Life

At the end of this lesson, students should be able to:
• Describe the origin of organic molecules
• Describe the origin of the first cells
• Define Biology as a science and the nature of scientific enquiry
• Outline the importance and applications of Biology
• Enumerate the relationship between Biology, Medicine and Agriculture.

INTRODUCTION
TRUE!!! Science has not been able to explain the Origin of Life convincingly or define life as it were so effectively. However, several attempts at explaining how we got here, how life came to be, have been discussed and argued at length by various scholars from different fields. Most religious scholars believe that life came to be by Intelligent Design. Others hold the loosely general belief that life

Biology come from two words; Bios meaning “life” and “logos” meaning knowledge. It is the aspect of science that is involved in the study of living things.
IMPORTANCE OF BIOLOGY
Biology is a wonder that affects almost every sphere of existence. The tenets of biology are deeply rooted in the following:
1. ENERGY FOR LIVING
The sun serves as the ultimate source of energy and it is endows living things with energy for living. Existence on earth requires a constant and continuous energy input.
2. INFORMATION TRANSFER
Organisms transmit genetic information from generation to generation. This information transfer helps to sustain life and improve living. This leads to the last tenet.
3. EVOLUTION
Evolution works on the process of natural selection and adaptations for survival of organisms. This leads to development of new traits and eventually into new species.

THE NATURE OF SCIENCE
The word “Science” meaning “to know” was developed from a Latin word. Science is a process and it is based on the following ordered steps.

No? Well you have no doubt seen plenty of dogs before. Have you ever seen a wolf? Unlikely, but you must have at least seen pictures on what wolves look like. You must have also noticed that though you could differentiate dogs from wolves, there were other little (and sometimes not so little) similarities between the two animals. These similarities include height, facial structure, and even behavioral tendencies. That is because both animals belong to the same genus but different species, each one similar and yet still different from the other. What sets apart each species from others in its genus? What relates each of them to the other? These questions are what the study of biodiversity gives answers
