Amazonian whale lives without males for 100,000 years
Scientists have discovered that the Amazonian dolphin, which reproduces using a male of a related species and has survived for over 100,000 years, relies on a natural mechanism called genetic conversion. This process corrects errors in its genes and helps ensure its survival despite the absence of sexual reproduction. Researchers believe that it originated around 100,000 years ago through a hybridization between two different species of molly fish, which contributed to its genetic diversity and ongoing existence.
