Biology assignment, need assistance
<p>Here's the code that I'm using to do an assignment on the theory of evolution in my Biology class. Now, I know there is a much simpler way I could've done this and I know it's lousy formatting, but all in all, I feel like i'm missing a bunch of stuff and I just want to know <strong>will this run?</strong> Please don't criticize my code, I know how to do things easier and better, I just did it this way. But is there anything i'm missing? I really need help. Thanks!   </p>
