Self-replication is a fundamental feature of life. It was proposed that self-replication emerged in the evolution of life when a molecule similar to a double-stranded polynucleotide (possibly like RNA) dissociated into single-stranded polynucleotides and each of these acted as a template for synthesis of a complementary strand producing two double stranded copies.

Replication (scientific method), one of the main principles of the scientific method, a.k.a. reproducibility Replication (statistics), the repetition of a test or complete experiment; Replication crisis; Self-replication, the process in which an entity (a cell, virus, program, etc.) makes a copy of itself
The first quantitative engineering analysis of a self-replicating spacecraft was published in 1980 by Robert Freitas, [56] in which the non-replicating Project Daedalus design was modified to include all subsystems necessary for self-replication. The design's strategy was to use the probe to deliver a "seed" factory with a mass of about 443 ...

The dynamics of the elementary hypercycle can be modelled using the following differential equation: [3] ˙ = (+,) where =, =. In the equation above, x i is the concentration of template I i; x is the total concentration of all templates; k i is the excess production rate of template I i, which is a difference between formation f i by self-replication of the template and its degradation d i ...
A self-replicating machine is a type of autonomous robot that is capable of reproducing itself autonomously using raw materials found in the environment, thus exhibiting self-replication in a way analogous to that found in nature.
