Ancestral of drosophila melanogaster?

10 October 2016 1 1K Report

I am doing evolutionary study of D. melanogestor genome. Which of the following should be treated as ancestral of drosophila melanogaster

Drosophila erecta , Drosophila simulans or Drosophila yakuba

Hello,

I don't think you can consider one of the species you showed (the relatives of D.me) as the ancestor of D.me. Though, they belong to the same subgroup of D.me. I think the following papers on phylogenetic trees of fruit flies can be helpful to you.
