Core Idea - Biological Evolution: Unity and Diversity
[3.LS.4.5] - Provide evidence to support a claim that the survival of a population is dependent upon reproduction.
State Assessment Boundary: Details of reproduction are not expected in state assessment.
[3.LS.4.2] -
Use evidence to construct an explanation for how the variations in characteristics among individuals within the same species may provide advantages to these individuals in their survival and reproduction.
Clarification Statements: Examples can include rose bushes of the same species, one with slightly longer thorns than the other which may prevent its predation by deer, and color variation within a species that may provide advantages so one organism may be more likely to survive and therefore more likely to produce offspring; Examples of evidence could include needs and characteristics of the organisms and habitats involved.
[3.LS.4.3] -
Construct an argument with evidence that in a particular environment some organisms can survive well, some survive less well, and some cannot survive. Clarification Statement: Examples of evidence could include needs and characteristics of the different organisms (species) and habitats involved.
