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.
