Chapter 1   Exploring Life

Lecture Outline

Overview: Biology’s Most Exciting Era

Concept 1.1 Biologists explore life from the microscopic to the global scale

 Organisms interact continuously with their environment.

 Cells are an organism’s basic unit of structure and function.


Concept 1.2 Biological systems are much more than the sum of their parts

  1. High-throughput technology. Systems biology depends on methods that can analyze biological materials very quickly and produce enormous amounts of data. An example is the automatic DNA-sequencing machines used by the Human Genome Project.
  2. Bioinformatics. The huge databases from high-throughput methods require computing power, software, and mathematical models to process and integrate information.
  3. Interdisciplinary research teams. Systems biology teams may include engineers, medical scientists, physicists, chemists, mathematicians, and computer scientists as well as biologists.

 Regulatory mechanisms ensure a dynamic balance in living systems.

Concept 1.3 Biologists explore life across its great diversity of species

  Living things show diversity and unity.

Concept 1.4 Evolution accounts for life’s unity and diversity

Concept 1.5 Biologists use various forms of inquiry to explore life

 We can explore the scientific method.

 Let’s look at the nature of science.

 Science and technology are functions of society.

Concept 1.6 A set of themes connects the concepts of biology
