4 なぜ生物学を学ぶかBiology, the study of life, is rooted in the human spirit. People keep pets, nurture houseplants, invite avian visitors with backyard birdhouse, and visit zoos and nature parks. This behavior express what Harvard biologist E. O. Wilson calls biophilia, an innate attraction to life in its diverse forms.
5 Biology is the scientific extension of this human tendency to feel connected to and curious about all forms of life. It takes us into the Nature, where a variety of living forms and their physical surroundings are interwoven into complex webs called ecosystems. Studying life leads us into laboratories to examine more closely how organisms work.
6 Biology draws us into the microscopic world of the fundamental units of organisms known as cell, and into the submicroscopic realms of the molecules that make up those cells. Our intellectual journey also takes us back in time, for biology encompasses not only contemporary life, but also a history of ancestral forms. The scope of biology is immense.From Campbell, Biology 4th ed. Chapter 1
