Definition: A trait that helps an organism survive and reproduce in its environment (e.g., the thick fur of Arctic foxes in cold weather).
Definition: The process by which two or more related populations become increasingly dissimilar over time, often due to different environmental pressures (e.g., varying beak shapes in Darwin's finches).
Definition: A taxonomic rank above species and below family, used to group closely related organisms (e.g., Canis).
Definition: A formal system of naming organisms using a two
part Latin identifier composed of the genus name and specific epithet (e.g., Homo sapiens).
Definition: Variants of a particular chemical element that possess the same number of protons but differing numbers of neutrons (e.g., carbon
efinition: The scientific study of the geographic distribution of plants, animals, and ecosystems through space and geological time.
Definition: The highest taxonomic rank in biological classification, comprising Archaea, Bacteria, and Eukarya.
Definition: A major taxonomic category ranking directly below domain and above phylum (e.g., Animalia or Plantae).
Definition: A branching diagram showing hypothetical evolutionary relationships among organisms based on shared traits.
Definition: Pertaining to cells containing a membrane bound nucleus and specialized organelles, characteristic of plants, animals, fungi, and protists.
Definition: A biological classification method that categorizes organisms based on shared derived traits and common ancestry.
Definition: The process through which populations of organisms change over generations via genetic variation and differential reproductive success.
Definition: The mechanism whereby individuals possessing advantageous heritable traits are more likely to survive, reproduce, and pass those traits to offspring.
Definition: A taxonomic rank situated between phylum and order that groups organisms sharing fundamental anatomical characteristics (e.g., Mammalia).
Definition: The irreversible termination and disappearance of an entire species or biological group.
Definition: A taxonomic level situated below class and above family that groups related families together (e.g., Carnivora)
Definition: A reciprocal evolutionary change in which two or more interacting species mutually affect each other's evolutionary trajectories (e.g., flowering plants and specialized pollinators).
Definition: A taxonomic rank between order and genus that encompasses one or more closely related genera (e.g., Felidae).
Definition: The evolutionary history, lineage, and branching relationships of an organism or group of organisms.
Definition: Traits or anatomical features that appear in recent descendants but were absent in the common ancestor.
Definition: The preserved remains, impressions, or traces of organisms from past geological periods preserved in Earth's crust.
Definition: The primary unit of biological classification, consisting of individuals capable of interbreeding and producing fertile offspring.
