Given information about living or extinct organisms, cite evidence to explain the frequency of inherited characteristics of organisms in a population, OR explain the evolution of varied structures (with defined functions) that affected the organisms’ survival in a specific environment (e.g., giraffe, wind pollination of flowers).

More specific sub-standards
illustrating that when an environment changes, the survival advantage/disadvantage of some characteristics may change.
distinguish between microevolution (on small scale within a single population – e.g., change in gene frequency within a population) and macroevolution (on a scale that transcends boundaries of a single species – e.g., diversity of all beetle species within the order of insects) and explain how macroevolution accounts for speciation and extinction.
recognizing patterns in molecular and fossil evidence, to provide a scientific explanation for Natural Selection and its evolutionary consequences (e.g. survival, adaptation).
using data or models (charts, diagrams, table, narratives etc.) to analyze how organisms are organized into a hierarchy of groups and subgroups based on evolutionary relationships. (e.g. creating a taxonomic key to organize a given set of examples).
explain punctuated equilibrium as a model of evolution and contrast it with a more gradual model of evolution.
