Study Notes
Distinction of Biological Matter
- Biological matter is characterized by the presence of organized cellular structures, complex biochemical processes, and the ability to reproduce and respond to stimuli.
- Non-biological matter lacks these processes and does not exhibit life functions such as metabolism, growth, or adaptability.
Definition of Viruses
- Viruses are challenging to define because they exhibit characteristics of both living and non-living entities.
- They possess genetic material (DNA or RNA) and can evolve, but require a host cell to replicate, lacking cellular structure and metabolism on their own.
Origin of Life
- Life is believed to have originated approximately 3.5 to 4 billion years ago on Earth, evidenced by the oldest fossil records and isotopic signatures.
Four Eternal Elements Theory
- The theory proposing that life was composed of four eternal elements: earth, water, air, and fire was presented by ancient Greek philosopher Empedocles.
Binomial Nomenclature
- The modern classification of living organisms through the system of binomial nomenclature was initiated by Carl Linnaeus in the 18th century, providing a standardized method for naming species.
