i do not understand this question and how to anseer it, can someone please help? htt p://i12. tinypic. com/6k8ytdd.jpg

the question is in the link because it has a graph that goes along with it that I do not understand, just take the spaces out of the link. but the question is: Come up with a evolution scenario involving natural selection for the graph. I do not understand the trend in the graph really...

due to natural selection the amount of birds that have lived throughout the 20 year period have been the birds with the bigger beaks because the food they need for survival burrows further into the ground therefor the lengths of the beaks for the birds must accommodate for the change thus the birds that lived have bigger beaks...something along those lines

if that doesnt make sense make it into your own words mentioning how the food goes deeper so the birds need bigger beaks to survive that where natural selection comes in because the birds who don't survive don't have big enough beaks and the birds that do survive "evolve" so to speak to have bigger beaks =]

I apologize, but I am unable to access external links or images. However, I can help you understand how to approach the question and how to analyze the graph.

To come up with an evolutionary scenario involving natural selection based on a graph, you need to understand the patterns and trends shown in the graph. Here are some steps you can take to analyze the graph:

1. Look for any key features: Examine the axes of the graph and note what variables are being represented. Determine the units of measurement and the range for each axis. This will give you a basic understanding of what the graph is illustrating.

2. Analyze the shape of the graph: Determine whether it is a line graph, bar graph, scatter plot, or any other type. Look for patterns such as trends, fluctuations, or consistent values.

3. Consider the trend: Determine whether the graph shows an increase, decrease, or remains relatively constant over time or across different categories. This will give you an idea of the overall direction of change.

4. Look for outliers or anomalies: Identify any data points that deviate significantly from the general trend. These outliers may suggest exceptions to the usual patterns and could be important for your evolutionary scenario.

Once you have a clear understanding of the graph, you can start thinking about how it relates to natural selection. For example, if the graph shows an increase in a particular variable over time, you can hypothesize that individuals with higher values of that variable have a higher fitness and hence are more likely to survive and reproduce. Conversely, if the graph shows a decrease, you can speculate that individuals with lower values have a survival advantage. These assumptions can form the basis for your evolutionary scenario.

Remember, without access to the specific graph you mentioned, it would be challenging to provide a detailed analysis or scenario. It's best to familiarize yourself with the graph and use the steps outlined above to analyze the trend and come up with a suitable evolutionary scenario involving natural selection.
