WY.SCI.HS.LS4.1
Wyoming Science Content and Performance Standards
Grades 9-12
Learning Domain: Biological Evolution: Unity and Diversity
Standard: Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
WY.SCI.HS.LS4.2
Wyoming Science Content and Performance Standards
Grades 9-12
Learning Domain: Biological Evolution: Unity and Diversity
Standard: Construct an explanation based on evidence that the process of evolution primarily result s from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
WY.SCI.HS.LS4.4
Wyoming Science Content and Performance Standards
Grades 9-12
Learning Domain: Biological Evolution: Unity and Diversity
Standard: Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
WY.SCI.HS.LS4.5
Wyoming Science Content and Performance Standards
Grades 9-12
Learning Domain: Biological Evolution: Unity and Diversity
Standard: Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
Science Domain: Life Sciences
Topic: Natural Selection and Evolution
Standard: Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence. [Clarification Statement: Emphasis is on a conceptual understanding of the role each line of evidence has relating to common ancestry and biological evolution. Examples of evidence could include similarities in DNA sequences, anatomical structures, and order of appearance of structures in embryological development.]
Science Domain: Life Sciences
Topic: Natural Selection and Evolution
Standard: Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment. [Clarification Statement: Emphasis is on using evidence to explain the influence each of the four factors has on number of organisms, behaviors, morphology, or physiology in terms of ability to compete for limited resources and subsequent survival of individuals and adaptation of species. Examples of evidence could include mathematical models such as simple distribution graphs and proportional reasoning.] [Assessment Boundary: Assessment does not include other mechanisms of evolution, such as genetic drift, gene flow through migration, and co-evolution.]
Science Domain: Life Sciences
Topic: Natural Selection and Evolution
Standard: Construct an explanation based on evidence for how natural selection leads to adaptation of populations. [Clarification Statement: Emphasis is on using data to provide evidence for how specific biotic and abiotic differences in ecosystems (such as ranges of seasonal temperature, long-term climate change, acidity, light, geographic barriers, or evolution of other organisms) contribute to a change in gene frequency over time, leading to adaptation of populations.]
Science Domain: Life Sciences
Topic: Natural Selection and Evolution
Standard: Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species. [Clarification Statement: Emphasis is on determining cause and effect relationships for how changes to the environment such as deforestation, fishing, application of fertilizers, drought, flood, and the rate of change of the environment affect distribution or disappearance of traits in species.]
