Core Idea
- Biological Evolution: Unity and Diversity
[8.LS.4.5]
- Synthesize and communicate information about artificial selection, or the ways in which humans have changed the inheritance of desired traits in organisms. Clarification Statement: Emphasis is on the influence of humans on genetic outcomes in artificial selection (such as genetic modification, animal husbandry, and gene therapy).

MCAS Items:
2019 Spring Release - Science and Technology/Engineering - Grade 8 - Item 16
Predecessor Standards:
3.LS.3.1
Provide evidence, including through the analysis of data, that plants and animals have traits inherited from parents and that variation of these traits exist in a group of similar organisms.Clarification Statements: Examples of inherited traits that vary can include the color of fur, shape of leaves, length of legs, and size of flowers; Focus should be on non-human examples. State Assessment Boundary: Genetic mechanisms of inheritance or prediction of traits are not expected in state assessment.
Successor Standards:
No Successor Standards found.
Same Level Standards:
RCA-ST.6-8.1
Cite specific textual evidence to support analysis of science and technical texts, quoting or paraphrasing as appropriate. (See grades 6-8 Writing Standard 8 for more on quoting and paraphrasing.)
WCA.6-8.8
When conducting research, gather relevant information from multiple print and digital sources, using search terms effectively; assess the credibility and accuracy of each source; and quote or paraphrase the data and conclusions of others while avoiding plagiarism and following a standard format for citation.
SLCA.6-8.2
Analyze the purpose of information presented in diverse media and formats (e.g., visually, quantitatively, orally) and evaluate the motives (e.g., social, commercial, political) behind its presentation.
8.LS.4.4
Use a model to describe the process of natural selection, in which genetic variations of some traits in a population increase some individuals’ likelihood of surviving and reproducing in a changing environment. Provide evidence that natural selection occurs over many generations. Clarification Statements: The model should include simple probability statements and proportional reasoning. Examples of evidence can include Darwin’s finches, necks of giraffes, and peppered moths. State Assessment Boundary: Specific conditions that lead to natural selection are not expected in state assessment.
