Winging It: Analyzing a Scientific Paper
INTRODUCTION

In 2017, biologists Linlin Zhang, Anyi Mazo-Vargas, and Robert Reed published the landmark scientific paper
“Single master regulatory gene coordinates the evolution and development of butterfly color and iridescence.”
The authors used CRISPR-Cas9, a tool for gene editing, to explore how inactivating certain genes affects colors
and patterns in the wings of many butterflies. They communicated their findings in a scientific journal so that
others in the scientific community could know about their claims, evaluate the evidence, repeat the
experiments, and use the information to design new experiments. Learning to interpret scientific research
papers is a critical skill. In this activity, you will analyze a portion of this colorful scientific paper.
PROCEDURE
Open the scientific paper Zhang et al. (2017). Read the “Abstract” (the first paragraph, written in bold font if the
paper is downloaded as a PDF) and the “Introduction” (the next two paragraphs).
1. The goal of the “Abstract” is to provide a brief summary of the paper. Most abstracts present the research
question, the methods used, the results, and the significance of the findings. In your own words, describe
the research question for this study.
2. The goal of the “Introduction” is to help readers understand why the research question is important. To do
this, scientists often briefly summarize what is and is not known about the research question, as well as
what they did to address the question. They may also describe the structure of the rest of the paper.
a. What argument do the authors make for why their research is important?
b. What do the authors say is known and not known about the genetics of butterfly wing patterns?
c. How do the authors prepare readers for reading the rest of the paper? Consider the entire
“Introduction” in your response
3. You will now make a concept map of the information in the “Introduction.” A concept map is a diagram that
shows the relationships among different concepts.
Create your concept map using the following terms as your concepts. Connect related terms with a line and
label each line with a brief phrase describing the relationship between the terms
 

Winging It: Analyzing a Scientific Paper
Read the article “Scientists Can Now Repaint Butterfly Wings,” which may be viewed online. This article describes
the butterfly study to a more general audience.
4. Create a diagram or cartoon to illustrate the experimental design described in this article. Your illustration
can be fairly general but should show how the scientists did the overall experiment.
 

Return to the scientific paper. Read the first three paragraphs of the “Results” and the caption for Figure 1.
5. What were the controls and experimental manipulations in this experiment? Give specific examples of each
from Figure 1
 

6. Annotate the copy of Figure 1 at the end of your handout by following the instructions below. Write
everything in your own words and in a way that a general audience would understand. a. Add a title for
the overall figure.

Student Handout
b. Write a simple driving question for each part of the figure labeled with a letter (A, B, C, etc.). In other
words, what question did the scientists try to answer in each part?
 

c. Write a simple summary of what is shown by each part of the figure labeled with a letter (A, B, C, etc.).
Your goal is to annotate the entire figure so that a reader could understand it without reading the
caption.

7. Create a new diagram or cartoon to illustrate the experimental designs of the experiments from Figure 1
only. Make sure to include how the scientists used controls. Refer to the “Materials and Methods” section of
the paper as needed to clarify the experiment. (Note you do not need to read this section in-depth. Many
scientists don’t either, unless they have a specific question about the procedure or want to do a similar
experiment.)
