Study Notes
Classifying Living Organisms
- Organisms are categorized into groups based on similarities and differences.
- Observable traits like leg count, wings, antennae, hair, shape, and vein patterns in leaves or insect wings are used for basic classification.
Modern Classification Techniques
- Scientists utilize internal structures, developmental patterns, life cycles, and electron microscopy for more detailed classification.
- DNA analysis is a crucial tool in modern classification.
- Organisms with similar DNA structures are considered more closely related.
Species
- The species is the fundamental unit of classification.
- A species comprises organisms with shared ancestry, similar physical features, and the capacity to interbreed and produce fertile offspring.
