- Simulations show technological evolution benefits from modularity, allowing complex circuits to evolve from simple components by recombining functional modules.
- Biological evolution similarly leverages modularity through genetic recombination, with sexual reproduction enabling faster information acquisition than asexual reproduction.
- Sexual reproduction allows genes from multiple parents to combine, testing gene fitness independently and speeding up evolutionary search compared to asexual reproduction.
- Asexual reproduction suffers from clonal interference, where beneficial mutations compete and one lineage dominates, slowing fitness increase.
- Information theory quantifies evolutionary progress, showing sexual reproduction accumulates bits of information faster by narrowing search spaces modularly.
- Horizontal gene transfer in bacteria provides some benefits of sexual reproduction by allowing gene sharing between organisms.
- The principles of modular search in evolution mirror those in technological development, both reducing complexity by testing components independently.
