NATIONAL SCIENCE EDUCATION STANDARDS
LSCell1: Cells have particular structures that underlie their functions.
LSEvol1: Species evolve over time.
LSEvol2: The great diversity of organisms is the result of more than 3.5 billion years of
evolution.
LSEvol3: Natural selection and its evolutionary consequences provide a scientific
explanation for the fossil record of ancient life forms as well as for the striking molecular
similarities observed among the diverse species of organisms.
LSEvol5: Biological classifications are based on how organisms are related.
LSMat4: The complexity and organization of organisms accommodates the need for
obtaining, transforming, transporting, releasing, and eliminating the matter and energy
used to sustain the organism.
LSBeh1: Multicellular animals have nervous systems that generate behavior.
UCP1: Systems, order, and organization
UCP3: Change, constancy, and measurement
