  • Biological Species Concept
    Definition based on reproductive isolation, focusing on whether populations can interbreed and produce fertile offspring.
  • Reproductive Isolation
    A condition where populations are unable to exchange genes, preventing them from producing fertile offspring together.
  • Morphological Species Concept
    Classification based on structural features and shape, useful for fossils and asexual organisms.
  • Morphology
    The study of an organism’s shape and structural characteristics, often used to distinguish species.
  • Ecological Species Concept
    Species identification based on unique interactions with the environment and occupation of distinct ecological niches.
  • Ecological Niche
    The specific role and position an organism occupies in its environment, including its interactions and resource use.
  • Phylogenetic Species Concept
    Recognition of species as the smallest evolutionarily distinct groups, often determined by unique branches on a phylogenetic tree.
  • Phylogeny
    The evolutionary history and relationships among populations or species, often depicted as a branching tree.
  • DNA Sequence Data
    Genetic information used to construct evolutionary trees and distinguish species based on genetic differences.
  • Gene Flow
    The movement of genetic material between populations, which can blur species boundaries under some concepts.
  • Asexual Organisms
    Populations that reproduce without mating, challenging species definitions based on reproductive compatibility.
  • Fossils
    Preserved remains or traces of ancient organisms, often classified using structural features due to lack of reproductive data.
  • Speciation
    The evolutionary process resulting in the formation of new, distinct populations that are reproductively isolated.
  • Evolutionary Tree
    A diagram showing relationships among species or populations, with branches representing evolutionary divergence.
