In a landmark study published on September 11, 2024, an international team of scientists has successfully mapped the genome of the Greenland shark (Somniosus microcephalus), the world’s longest-living vertebrate. This research provides unprecedented insights into the genetic mechanisms behind extreme longevity in vertebrates. Key Findings The Greenland shark genome, spanning 6.5 billion base pairs, is twice the size of the human genome and the largest among shark genomes sequenced to date. Over 70% of this massive genome consists of transposable elements, often referred to as “jumping genes” or “selfish genes.” Dr. Arne Sahm, the study’s lead author, explains, “There are … Continue reading Greenland Shark’s 500-Year Lifespan Linked to Massive 6.5 Billion Base Pair Genome: Secrets of Longevity Revealed
