Cloning yourself is faster, cheaper, and guarantees your genes survive intact. So why does nearly every complex organism bother with the messy, energy-draining process of mixing genes with a partner? Drag the slider to shift environmental stability and watch which strategy dominates.
Asexual reproduction creates genetic clones through mechanisms like binary fission (bacteria split in two), budding (hydra grow miniature copies), vegetative propagation (strawberry runners generate new plants), and parthenogenesis (some lizards and insects develop embryos without fertilisation). It's energetically cheap, requires no mate-finding, and guarantees every offspring carries 100% of your genes. In stable environments where conditions rarely shift, this strategy dominates — a perfectly adapted clone is perfectly adapted forever. But when pathogens evolve to crack your genetic defences, every clone in the population becomes equally vulnerable, and a single disease can wipe out the entire lineage in one sweep.

Sexual reproduction costs time and energy but generates genetic variation through gamete fusion, making populations resilient against rapidly evolving parasites.
