Question
Based on the results of the bird beak activity, which of the following statements are conclusions that can be drawn regarding evolution by natural selection. Select all that apply. Partial credit will be given.
Question 4 options:
all of the beak phenotypes in the population were equally successful at obtaining all seed types.
a trait such as beak phenotype may be advantageous in one environment but may no longer be advantageous if the environment changes.
individuals with an advantageous trait will be better able to collect food, they will survive and pass that trait on to their offspring. Therefore, the frequency of this advantageous trait will increase in subsequent populations.
a beak that is beneficial for obtaining one type of food item may not be beneficial if that food item is removed, or replaced with a different food item.

Based on the bird beak activity results and the principles of evolution by natural selection, the following statements can be considered valid conclusions:
1. **A trait such as beak phenotype may be advantageous in one environment but may no longer be advantageous if the environment changes.**
- This statement reflects the idea that traits can provide varying advantages depending on environmental conditions.
2. **Individuals with an advantageous trait will be better able to collect food, they will survive and pass that trait on to their offspring. Therefore, the frequency of this advantageous trait will increase in subsequent populations.**
- This statement summarizes the core concept of natural selection: traits that confer an advantage in survival and reproduction are likely to be passed on to future generations, leading to an increase in the frequency of those traits in the population.
3. **A beak that is beneficial for obtaining one type of food item may not be beneficial if that food item is removed, or replaced with a different food item.**
- This statement emphasizes the dependency of advantageous traits on specific environmental conditions and resources, aligning with the principles of natural selection.
The first option, **"All of the beak phenotypes in the population were equally successful at obtaining all seed types,"** is not a valid conclusion, as it contradicts the concept of natural selection, which implies that some phenotypes are more advantageous than others in specific contexts.
In summary, the suitable conclusions from your list regarding evolution by natural selection are the second, third, and fourth statements.
