A Study Guide for Chapter 1
Evolution, Biology's Themes
Campbell Biology: Third Canadian Edition
UOA
BIOL(10)8
Key Concepts and Important Points
1. Five Themes of Biology
● Organization: Biological systems are structured in a hierarchical
manner, from molecules to the biosphere.
● Information: Life processes involve the expression and transmission of
genetic information.
● Energy and Matter: Living organisms require the transfer and
transformation of energy and matter.
● Interactions: From molecules to ecosystems, interactions are crucial
in biological systems.
● Evolution: The core theme that accounts for the unity and diversity of
life. Evolution explains the adaptations of organisms and the natural
selection process.
2. Scientific Inquiry in Biology:
● The chapter discusses the scientific method, the importance of
observation, hypothesis formation, experimentation, and data
analysis.
● It introduces a case study on the Canadian Yew tree to illustrate the
application of scientific inquiry in understanding biological
phenomena.
