We identified 15 regions of >1 Mb in the human genome composed of large ancient local duplications corresponding to gene deserts. We detected these intrachromosomal duplications in mouse and dog but not in chicken; they present as patches of similarity as low as 60%. These findings suggest that some human gene deserts originated from duplications of segments lacking genes in a mammalian common ancestor.
