Study Notes
Matter and Biological Processes
- Matter with biological processes is distinguished from matter without by the presence of organization, metabolism, homeostasis, growth and development, reproduction, response to stimuli, and evolution.
Origin of Life
- The origin of life is unknown, but it is believed to have emerged around 3.5-4.5 billion years ago.
Viruses as Living Organisms
- Defining viruses as living organisms is difficult because they do not exhibit all the characteristics of life (e.g., they are not cellular, do not metabolize, and do not replicate independently).
Empedocles's Materialism Theory
- Empedocles's materialism theory asserted that life arose from the combination of four elements: earth, air, fire, and water.
Carl Linnaeus's Contributions
- Carl Linnaeus contributed to the study of living things by developing the taxonomy system used to classify organisms into kingdoms, phyla, classes, orders, families, genera, and species.
Aristotle's Hylomorphism Theory
- Aristotle's hylomorphism theory asserted that living things have both matter (hyle) and form (morphe), with the form being the essential characteristic that defines a living thing.
