Drosophila Melanogaster vs Human

Drawn on my Microsoft Surface Pro 3 using One Note application and a surface pro pen.

On the left is half of a Drosophila Melanogaster fly’s face. On the right is a human face.

The Drosophila Melanogaster fly is a popular species used for biological studies. Its easily manipulative life is carefully studied for genome sequencing. About 75% of known human disease genes have a recognizable match in the genome of fruit flies. 
The Drosophila Melanogaster fly has been used as a genetic model in research in human diseases such as Parkinson’s, Huntington’s, spinocerebellar ataxia and Alzheimer’s disease.
