Genomic stability: A double-edged sword for sharks https://phys.org/news/2023-10-genomic-stability-double-edged-sword-sharks.html

Low mutation rate in #EpauletteSharks is consistent with a slow rate of #evolution in #sharks: Ashley Sendell-Price et al. https://www.nature.com/articles/s41467-023-42238-x

"With an estimated #MutationRate of 7Γ—10-10 per base pair per generation, they have the lowest mutation rate yet recorded in #vertebrates. It is ten to twenty times lower than in #mammals."

Genomic stability: A double-edged sword for sharks

Sharks have been populating the oceans for about 400 to 500 million years. While our planet and many of its inhabitants have undergone massive changes several times during this period, this basal group of vertebrates has remained somewhat constant. Their body shape and biology has hardly changed since then.
