What is the definition of the term species?
A species is defined as a group of organisms capable of passing genetic information within the group because the organisms can reproduce with one another.

Study Notes
Definition of Species
- A species consists of organisms capable of interbreeding and passing genetic information.
Grouping Organisms into Species
- Organisms are classified as a species based on shared physical characteristics and reproductive capabilities.
- Offspring produced by species can also reproduce, maintaining continuity within the group.
Classification of Organisms
- Every type of organism, including extinct ones, can be classified.
Basis of Classification
- Classification relies on physical traits; organisms may have backbones or be single-celled versus multi-celled.
- Uses an established hierarchy: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Dichotomous Key Usage
- A dichotomous key classifies organisms through a series of characteristic statements.
- Users select between two choices leading to further statements until an organism is identified.
Scientific vs. Common Names
- Common names are numerous and can refer to different organisms, whereas each species has a unique scientific name.
Creation of Scientific Names
- Scientific names comprise two parts: genus and species.
- Typically derived from Latin or Greek terms describing the organism's traits or characteristics.
Significance of Scientific Names
- A scientific name reveals the genus and species, providing insights into related organisms and evolutionary history.
- Translatable Latin or Greek names can indicate physical appearance, habitat, diet, and behavior.
Classification Criteria
- Scientists classify organisms based on shared physical features, such as respiratory systems or skeletal structures.
- Behavioral traits, including reproductive methods, are also considered in classification.
Linnaean System of Classification
- Organisms are categorized by shared characteristics in a hierarchical system: kingdom (largest) down to species (smallest).
- Each taxonomic group serves to arrange living things according to their similarities and differences.
