Generic

the minimal requirement for natural selection is that each kind of replicator produce at least one viable offspring, on average, per lifetime—so that the different kinds of replicators last long enough to be ‘selected’ by the environment. In challenging environments, a vehicle with many functionalities is needed to meet this requirement. But in unchallenging ones (i.e. sufficiently unchanging and resource-rich, such as pre-biotic ones), the requirement is easily met by inaccurate self-reproducers, without a vehicle. These not only have no appearance of design, but also are so inaccurate that they can have arisen spontaneously from generic resources under no-design laws—as proposed, for instance, by the current theories of the origin of life-- Chiara Marletto.
