Question

You are a field biologist interested in demonstrating evolution in a population of crickets that you have studied for two years. During that time, the average mass of individuals (a quantitative trait) has increased (see the data graphed below in picture).

1. Present graphs of two other data sets you could collect that will convince others that the changes you have observed are the result of evolution by natural selection. Label axes and titles.

2. Write a sentence or two that explains what each graph illustrates.

125 opservea change 100 75 à 75 2 25- 14 16 18 20 cricket mass (grams)

Explanation / Answer

As the frequency of density is increasing after certain extent there is decline indicating those evolved better to the In   

existing competition could survive.

In both the sets same phenomenon except change in initial and final quantative mass.
