Nothing decent, anyway.
Evolution is the justification for using model organisms such as yeast, zebrafish, fruit flies and mice. Indeed, we find many genes that are common between species because of common descent.
That's why humans have a gene called lunatic fringe. It was first discovered in fruit flies, where researchers named it after what the fly looked like after knocking the gene out. The name kinda stuck after that.
Even if you don't do evolutionary biology and even think about evolution, it is still important to many biological sciences.
