After the initial divergence event between human and mouse, both genomes underwent their highest rates of DNA loss which continued to slow down throughout their evolution (Fig 8a and 8b).

This was thought to be the case because there were mutant Pax3 proteins in mice and humans that had defects in the parts of the protein that bind to DNA, and so, would not be able to properly turn genes «on» or «off.»

To better characterise the molecular drivers and evolutionary impacts of DNA gain and loss, we calculated lineage - specific gain and loss rates across the human and mouse genomes.
