Study Notes
Biological Matter
- Biological matter is distinguished from non-biological matter by the presence of biological processes such as metabolism, homeostasis, and the ability to respond to stimuli, grow, reproduce, and evolve.
- The difficulty in defining viruses as living organisms lies in their inability to carry out metabolic processes independently and their requirement of a host cell to replicate.
Ancient Concepts of Life
- According to Empedocles's materialism, life was composed of four elements: earth, air, fire, and water.
- Aristotle's hylomorphism asserted that living things consist of both matter (hyle) and form (morphe), with the form being the essential aspects of a living thing that distinguish it from non-living matter.
Extent of Life on Earth
- Life has been found to exist almost everywhere on Earth, including extreme environments such as hot springs, Antarctic ice sheets, and deep-sea vents.
