NO EXAMPLES. "With the exception of biological organisms, we have no examples of self-replicating, evolving chemical systems." https://lnkd.in/dhc7k7H View in LinkedIn

CRYSTALLINE DNA. "I construct a chemical system that preliminary evidence suggests is capable of the most basic self-replication and evolution. The system uses no enzymes or biological sequences, can support and replicate a combinatorial genome, and is completely autonomous." https://lnkd.in/dhc7k7H View in LinkedIn

INFORMATION. "This work suggests that the concept of a self-replicating chemistry is closely related to the concept of a chemistry that can store information and compute." https://lnkd.in/dhc7k7H View in LinkedIn

KEY TO GREY ZONE. "It is only by clearly understanding how chemical systems can transfer and process information that we can hope to understand how self-replication and evolution can occur, and by implication, understand how life might have begun." https://lnkd.in/dhc7k7H View in LinkedIn

COMPUTING MOLECULES. "Paul Rothemund showed chemical processes could perform not just complex, but universal computation: a combination of DNA strands and restriction enzymes could, in principle, simulate a Turing machine. Thus, the simplest kinds of chemistry can, in theory, perform any computation.” https://lnkd.in/dhc7k7H View in LinkedIn

"LIVING ORGANISMS are very complicated aggregations of elementary parts, and by any reasonable theory of probability or thermodynamics highly improbable. That they should occur in the world at all is a miracle of the first magnitude; the only thing which removes, or mitigates, this miracle is that they reproduce themselves. Therefore, if by any peculiar accident there should ever be one of them, from there on the rules of probability do not apply, and there will be many of them, at least if the milieu is reasonable.

DEFINITION OF COMPUTER VIRUS: "a virus as a piece of code with two characteristics: 1. At least a partially automated capability to reproduce. 2. A method of transfer which is dependent on its ability to attach itself to other computer entities (programs, disk sectors, data files, etc.) that move between these systems.” https://lnkd.in/eCG7b3z View in LinkedIn

"VIRUSES are primarily a set of instructions, which execute over time on some hardware. Viruses are based on algorithms, which essentially represent a pattern in time. Viruses are not entities that survive on their own, but rather rely on a host entity to execute and reproduce. In most cases, the host entity is a computer on which the virus resides and propagates." https://lnkd.in/dSdcD2A View in LinkedIn

HOST PARASITES. "Simply put, viruses are small programs designed with (usually) malicious intent that attach themselves to other programs or files. They are capable of copying themselves throughout a computer or computers. They are called viruses because of the way they emulate their biological namesakes. A virus will infect healthy programs in a host computer and then spread to other healthy hosts, infecting them as well." https://lnkd.in/dhKz_EK View in LinkedIn
