Your draft contains quite a few gaps and leaves me with some questions. There still exist people unable to roll their tongue, while others tie cherry stems in knots. Clearly this is not learned behavior or something dependent upon one's environment. While you have, as of yet, produced no gene for this trait, I think you'll find an allele hiding out somewhere. Try to do a better job of checking your work, both on this subject and in general.

Despite these gaps, a rough base pair count shows that it took you approximately 3.12 billion chemical base pairs to state your point. While it is important to leave no stone unturned, I wanted to stop reading after 2 billion base pairs. Try trimming things back a bit for the sake of readability. For an example of what a concise, to-the-point genome looks like, check out my work on the mouse. Try to footnote any thoughts not your own. Get to know Microsoft Word's "base pair count" feature. I hope these comments haven't discouraged you. Keep up the hard work, and you'll be rewarded. If you wish to discuss your grade or any potential for improvement, come to my office hours, which are listed on the syllabus, or make an appointment with my secretary.
