Study Notes
Introduction to Biology Today
- Biology is the scientific study of life
- Taxonomy is the science of naming and classifying organisms
- The Mars rover aims to search for signs of life on Mars
Biology All Around Us
- Most people have an inherent interest in life
- Biology is vital in the understanding of health, fitness, and the importance of nature
- Chapter topics vary but include medical aspects, society aspects, biological importance, and relationships within the subject of biology
The Scientific Study of Life
- Biology is the scientific study of life
- Science is an approach to understanding the natural world grounded in inquiry, which is the search for information, explanations, and answers to questions
- Two principal forms are discovery science and hypothesis-driven science
- Data (recorded observations) are the foundation of scientific inquiry.
- Science distinguishes itself from supernatural beliefs as data must be verifiable.
The Process of Science
- Biology is the scientific study of life
- Scientific studies involve observations and measurements
- These observations lead to questions and hypotheses
- Hypotheses are tentative explanations that require testing
- Predictions are developed based on the hypothesis, and testing follows predictably
- Experiments are conducted to test the hypothesis and predictions
- Experiments can lead to revised hypotheses or additional questions
- Scientists often incorporate discovery science and hypothesis-driven science in conjunction with one another
Theories in Science
- Facts, while important, are not the primary objective of science
- Theories are broad statements encompassing a wide range of observations, supported by evidence, and capable of generating new testable hypotheses
- A theory emerges when a large amount of evidence supports a particular explanation
- Scientific theories continually revise and develop as more data emerges.
The Nature of Life
- Biology is the scientific study of life.
- There's no single, concise definition of life.
- Living things exhibit certain characteristics, such as: order, reproduction, growth, adaptation, and evolution.
Major Themes in Biology
- Evolution: living things evolve (change) from ancestral species over time
- Structural/functional relationship: Structure relates to function, and vice-versa
- Information flow: information is passed from one cell to another, from one organism to another
- Energy Transformations: Organisms receive, transfer, and use energy
- Interconnections: living things are interconnected within biological systems
