Study Notes
Reproduction Basics
- Reproduction is not necessary for individual survival, as an organism can maintain its life without reproducing.
Species Identification
- Two individuals are typically identified as belonging to the same species if they can interbreed and produce fertile offspring.
Body Designs
- Organisms with similar body designs are more likely to be capable of interbreeding and producing fertile offspring.
Reproduction Purpose
- The main purpose of reproduction is to create new individuals with similar characteristics to ensure the survival of the species.
DNA Copying
- DNA copying must be accompanied by the creation of an additional cellular apparatus to ensure the integrity of the genetic material.
Genetic Variations
- Drastic variations in a new DNA copy can lead to cell death or the creation of non-viable offspring.
- Surviving cells after reproduction are similar but subtly different due to genetic variations during DNA copying.
Evolution
- The basis for evolution is the accumulation of genetic variations over time, which can lead to the formation of new species.
Population Stability
- Reproduction is linked to the stability of populations of species, as it ensures the continuation of the species and the maintenance of population sizes.
