The origins and molecular evolution of sperm
2025-11-03
Abstract excerpt
<h4>Summary</h4> Sperm is a nearly universal cell type among animals, yet its evolutionary origins remain unclear. Using comparative proteomics and phylogenomics across 32 species, we reconstruct the 700+ million year evolutionary history of sperm to define the Last Universal Common Sperm (LUCS), a conserved core of 301 gene families enriched in motility and energy metabolism. We found that most of the LUCS toolk...
