In order to make a proper investigation using the scientific method we have to follow the following statements.
- Create three or more groups of flamingos. One control group were the flamingos will be fed by their occasional diet. A second group with a diet with no artificial or natural dye, as β-Carotene, which is high present in seaweeds. The third group will have a diet with a high amount of β-Carotene.
- The color of the groups will be analyzed to see the changing of pigmentation by time. If the group which is fed by B-Carotene increases the pigmentation, it might indicate a diet factor.
- As counterproof, a sample of DNA of the groups has to be taken. If is there any pattern between the groups of no-colored flamingos and a pattern of colored ones. It can indicate a genetic factor. If not, the diet can be responsible for it.
