Core Idea - Biological Evolution: Unity and Diversity
[HS.LS.4.5] - Evaluate models that demonstrate how changes in an environment may result in the evolution of a population of a given species, the emergence of new species over generations, or the extinction of other species due to the processes of genetic drift, gene flow, mutation, and natural selection.
[WCA.9-10.9] -
Draw evidence from informational texts to support analysis, interpretation, reflection, and research. (See grades 9-10 Reading Standard 1 for more on the use of textual evidence.)
[HS.LS.4.2] -
Construct an explanation based on evidence that Darwin’s theory of evolution by natural selection occurs in a population when the following conditions are met: (a) more offspring are produced than can be supported by the environment, (b) there is heritable variation among individuals, and (c) some of these variations lead to differential fitness among individuals as some individuals are better able to compete for limited resources than others. Clarification Statement: Emphasis is on the overall result of an increase in the proportion of those individuals with advantageous heritable traits that are better able to survive and reproduce in the environment.
