Eukaryotic performance hinges on the coordinated function of the products of the nuclear and mitochondrial genomes in achieving oxidative phosphorylation. Because two genomes are involved, function is maintained only through perpetual selection for mitonuclear coadaptation. I’ll discuss how these fundamental features of the genomic architecture of eukaryotes results in both pre- and post-zygotic sorting for coadapted mitonuclear genotypes leading to both speciation and sexual selection, highlighting recent work with songbird coloration.


Geoff completed his Ph.D. at the University of Michigan, followed by a Postdoc at Queen’s University, Canada. He is currently, the curator of birds and professor of biology at Auburn University, where he has worked for 25 years. Geoff has written five books and is currently writing his 6thbook on the coadaptation of mitochondrial and nuclear genes. Geoff’s research interests include animal coloration, sexual selection and speciation.
