Study Notes
Taxonomy and Classification
- Scientific naming involves genus and species; for humans, the name is Homo sapiens.
- Every species has a specific epithet; examples include Panthera tigris for tigers and Solanum nigrum for black nightshade.
Genus
- Genus groups closely related species sharing more characteristics than those from different genera.
- Examples include both potato (Solanum tuberosum) and brinjal (Solanum melongena), which belong to the same genus, Solanum.
- Panthera genus includes lion (Panthera leo), leopard (Panthera pardus), and tiger (Panthera tigris), while Felis includes domestic cats.
Family
- Family comprises genera with fewer similarities than those found in genus or species.
- Characterization relies on genuine vegetative and reproductive features.
- Examples:
- Genera Solanum, Petunia, and Datura are classified under the family Solanaceae.
- Panthera and Felis are part of the family Felidae; canines are classified under Canidae.
Order
- Order and higher taxonomic categories are formed based on groups of organisms sharing common characteristics.
- Example: Insects share features such as three pairs of jointed legs.
- Taxonomic ranks include kingdom, phylum (or division for plants), class, order, family, genus, and species.
Species
- A species is a group of individuals showing fundamental similarities and can be distinguished by distinct morphological features.
- Examples of specific epithets within distinct genera:
- Mangifera indica (mango),
- Solanum tuberosum (potato),
- Panthera leo (lion).
Biodiversity
- Global biodiversity estimates range between 1.7 to 1.8 million known species.
- Exploration leads to the continuous identification of new organisms; biodiversity includes both visible and microscopic life forms.
Nomenclature
- Standardized naming is essential for clear communication about organisms, preventing confusion from local naming variations.
- Nomenclature requires accurate descriptions and proper identification of organisms; it’s a process established by scientists.
