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.
