Mitochondrial genes have incongruent histories linked to their chromosomal position and function

Mitochondrial DNA has been one of the key workhorses of evolutionary studies. Hence understanding the dynamics of DNA sequence change in this tiny genome (15 to 20 kilobases) is of utmost importance. However, we are unaware of large studies examining how the functionality and chromosomal positioning of mitochondrial genes may impact the evolutionary histories that they depict. To examine this, we assembled a large database of animal mitochondrial genomes (> 10,000 total individuals over 89 taxonomic groups) and compared their phylogenetics, functionality, and location on the mitochondrial genome (heavy or light strand, and distance from origin of replication). We found that many genes show unique evolutionary patterns, often directly tied to chromosomal location or function of the gene (e.g. NADH dehydrogenases or ribosomal genes). We also found rampant phylogenetic incongruence among the linked genes of the mitochondrial circular chromosome in most of the taxonomic groups we examine..., , # Mitochondrial genes have incongruent histories linked to their chromosomal position and function

**Description of the data and file structure**

This site holds the data used for a study by DeSalle and Tessler entitled \"Mitochondrial genes have incongruent phylogenetic patterns linked to their chromosomal position and function\".

1.     The file entitled \"Mitom_Supplemental XXXXXXXXTable 1.xlsx\" is an Excel file with tabbed sheets. The first sheet holds all of the accession numbers of the genomes used in the study. The second sheet holds a table showing the phylogenetic distribution of the animal groups examined in the study. The third sheet gives the names of the nexus files for each taxon included in the study.

The column headers in the table 1 tab are defined as follows

*Abbrev*: Abbreviation used in study.

*scientific name*: Full binomial names of the taxa in the study          

*common name*: The taxonomic grou...,
