HS-LS2-8
Evaluate the evidence for the role of group behavior on individual and species’ chances to survive and reproduce.
Clarification statement: Emphasis is on: (1) distinguishing between group and individual behavior, (2) identifying evidence supporting the outcomes of group behavior, and (3) developing logical and reasonable arguments based on evidence. Examples of group behaviors could include flocking, schooling, herding, and cooperative behaviors such as hunting, migrating, and swarming.

NGSS Dimensions
Performance expectation HS-LS2-8 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Engaging in argument from evidence: Evaluate the evidence behind currently accepted explanations or solutions to determine the merits of arguments.
- Scientific Knowledge is Open to Revision in Light of New Evidence: Scientific argumentation is a mode of logical discourse used to clarify the strength of relationships between ideas and evidence that may result in revision of an explanation.
- Social interactions and group behavior: Group behavior has evolved because membership can increase the chances of survival for individuals and their genetic relatives.
- Cause and effect: Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.
