The description of a barcode mainly serves to:. A. trivialize the complexity of a particular research practice.
B. use a familiar concept to communicate an idea.
C. question the novelty of a scientific phenomenon.
D. inject a note of levity into an otherwise serious argument.

B. use a familiar concept to communicate an idea.

Explanation:

From the article written by Tim Heupink, et al, and titled "Dodos and Spotted Green Pigeons are Descendants of an Island Hopping Bird"

Following the scientist's analysis on DNA from two feathers of green pigeon which were seen they examined the minor area of DNA that are distinct for most bird species. This minor area comprises three DNA “mini barcodes." It was concluded from the analysis of mini Barcodes that the green pigeon that were discovered is certainly a different species, indicating a distinct DNA barcode compared

Hence, it can be concluded that the description of a barcode mainly serves to use a familiar concept to communicate an idea.
