Genetics, the science of heredity, is vital to understanding aging and advancing transhumanism. It uncovers genes affecting lifespan and health, driving innovations like gene therapy and epigenetic reprogramming. Gene editing, powered by tools like CRISPR, allows precise modifications to DNA, offering breakthroughs in curing diseases, enhancing traits, and combating aging. From a transhumanist view, genetics and CRISPR hold the key to extending life, enhancing abilities, and overcoming human biological limits.
