7th Grade (SCI) Life Science Standards [LS4] Biological Evolution: Unity and Diversity
SCI-MS.LS4.04 Construct 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.
Clarification Statement: Emphasis is on using simple probability statements and proportional reasoning to construct explanations. Disciplinary Core Ideas LS4.B: Natural Selection
Natural selection leads to the predominance
of certain traits in a population, and the
suppression of others.
Student Learning Targets:
I can recognize or recall specific terminology (geographic isolation, mutation, variation, adaptation, natural selection, trait, evolution, species, vestigial structures, DNA, embryology, homologous structures).
I can list the three sources of variation (mutation, geographic isolation, movement).
I can recall Charles Darwin’s principals of natural selection.
I can explain how variation in a population can lead to the formation of a new species.
I can explain why variation is important in a population.
I can describe the effects of natural selection.
I can list and explain the evidences of evolution.
