Study Notes
Biodiversity
- Refers to the variety of organisms at all taxonomic levels and the ecosystems they inhabit.
Biological Evolution
- The process that generates biodiversity among species.
Taxonomy
- The science dedicated to the classification of organisms, encompassing naming, describing, and categorizing living things.
Category in Taxonomy
- A rank of classification within taxonomy, such as genus or family.
Taxon
- A named taxonomic unit representing a group of organisms, examples include Homo sapiens, Hominidae, or Mammalia.
Taxa
- The plural form of taxon.
Basic Taxonomic Categories
- The eight fundamental categories are: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species (Mnemonic: Dubious kings play chess on fine grain sand).
Domain Eukarya
- Includes organisms with cells that contain a membrane-bound nucleus and membranous organelles.
Kingdom Animalia
- Characterized as multicellular organisms lacking cell walls or chlorophyll, with an ingestive nutrition system and internal digestion.
Phylum Chordata
- Distinguished by the presence of a notochord, dorsal tubular nerve cord, pharyngeal pouches, gill slits, and a postanal tail.
Class Mammalia
- Notable for features like mammary glands, hair, three ear ossicles, heterodont dentition, a squamosal-dentary jaw articulation, an attached placenta, well-developed facial muscles, a muscular diaphragm, and a four-chambered heart.
Order Primates
- Identified by large cerebral hemispheres, forward-facing orbits, ball-and-socket limb articulations, pentadactyl limbs with opposable digits, flattened nails, and variation in tail presence.
Family Hominidae
- Characterized by larger body size, sexual dimorphism (males larger than females), well-developed upper extremities, opposable thumbs and toes, absence of tails, longer hind limbs than arms, climbing abilities (except for humans), and a unique dental structure.
