Self-replication is the process by which an organism or system can create a copy of itself. This phenomenon is fundamental in biology, where living organisms, such as cells, reproduce through mechanisms like mitosis or meiosis. In these processes, genetic material is duplicated and passed on to new cells, ensuring the continuation of species. In technology, self-replication can refer to systems or machines that can produce copies of themselves. This concept is explored in fields like robotics and nanotechnology, where machines or molecular structures can autonomously create duplicates, potentially leading to advancements in manufacturing and resource efficiency.
