In this species of tiny animal called an ostracod, males are smaller than females and have special light organs that they use to compete for females by emitting flashes of bioluminesence.

NEXT GENERATION SCIENCE STANDARDS (NGSS)


The Sexual Selection teaching resources support students in meeting the following middle school NGSS Performance Expectations:

Life Science

MS-LS2

Ecosystems: Interactions, Energy, and Dynamics
    MS-LS2-1Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.MS-LS2-2Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.MS-LS2-4Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

MS-LS4

Biological Evolution: Unity and Diversity
    MS-LS4-4Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing in a specific environment.
