Biology means the study of living things. Biologists investigate animals, plants, and microbes in many different ways, and on a huge range of scales from molecules and cells to individual organisms, populations, and ecosystems.

During the past few decades, the study of biology has undergone rapid change and has had a significant impact on the way we live. We are now able to produce antibiotics and vaccines, grow disease-resistant crops, transplant organs, and manipulate genes. Biologists today are actively researching solutions to vital concerns such as increasing world food supply, improving and protecting our environment, and conquering disease.
