Organisms with advantageous inheritable traits tend to increase in proportion to those without the trait.

• Determine patterns of change in distribution of traits over various times
and population scales.
• Explain that natural selection causes increases and decreases in heritable traits if it affects reproductive success
• Explain the changes in advantageous heritable traits.
• Individuals can have traits that give them a competitive edge over other individuals in the species.Use resources that explain that natural selection leads to adaptations of populations.
• Use reasoning and evidence that organisms can adapt to biotic and abiotic factors in their environment.
• Distinguish between cause and correlation in an explanation of how natural selection allows species to adapt to changes in their environment.Write a reflection about your learning in this unit. Your reflection should be at least 3 sentences. Use the following sentence starters as a guide.

One thing that was hard for me was understanding the concept of natural selection and how it leads to changes in heritable traits. The examples and explanations provided in the unit were helpful in clarifying this concept and making it easier to grasp. However, I am still confused about the distinction between cause and correlation in explaining how natural selection allows species to adapt to changes in their environment. I will need to review this topic further to fully understand it.
