The paper tests for sexually antagonistic coevolution in Drosophila by analyzing female post-mating transcriptomes and finds no evidence of coevolution, instead supporting environmental and female-expressed genetic factors.

The paper develops Bayesian methods to quantify transcriptome turnover across species, finding accelerated gene expression changes in testes and accessory glands of Drosophila species.

This study identifies young, polymorphic de novo genes in Drosophila melanogaster by sequencing tissue-specific transcriptomes, revealing their transient nature and challenges in reconstructing their origin.
