Unit 1 Wrap Up- Evolution

Unit one is an important building block for Biology. So far, we have referenced evolution in every unit so far, ranging from cell chemistry to the endosymbiotic theory.

In unit 1, we were able to employ SP1. We employed SP1 when using the Hardy-Weinberg equilibrium, which models an unchanging hypothesis. Hardy-Weinberg equilibrium is meant to serve as a null hypothesis, because if you can prove that the Hardy-Weinberg equation isn't true, then evolution is happening in a population, and helps serve as a model for evolution. Another model invented by the same scientists is the idea of the Hardy-Weinberg equation, which is used to calculate the genotype/phenotype frequencies in a population that isn't evolving.  This also works with SP2, which is using mathematics appropriately. I initially had trouble using the H-W equation, but was able to eventually lean how to use it by the end of unit 1. 

I plan on continuing to apply the principles of evolution to other topics in AP Biology, and hope that this unit will be helpful in my future study.

Unit Objectives

• Change in the genetic makeup of a population over time is evolution.
• Organisms are linked by lines of descent from common ancestry.
• Life continues to evolve within a changing environment.
• The origin of living systems is explained by natural processes.
• Timing and coordination of behavior are regulated by various mechanisms and are important in natural selection
• 
  

Science Practices

• SP1:The student can use representations and models to communicate scientific phenomena and solve scientific problems.
• SP2: The student can use mathematics appropriately.
• SP3: The student can engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course.
• SP4: The student can plan and implement data collection strategies appropriate to a particular scientific question.
• SP5: The student can perform data analysis and evaluation of evidence.
• SP6: The student can work with scientific explanations and theories.
• SP7: The student is able to connect and relate knowledge across various scales, concepts and representations in and across domains.
