FRAGMENT FROM NATURE concludes this weekend on the theme of the (nearly) universal genetic code, and the deviations from this code. In a world where everything evolves and diversification is the common factor, having a highly conserved code is perplexing. And for sure, in the beginning, it was not how it is today. How did this arise? View in LinkedIn

ARTIFICIAL LIFE. "The modeling philosophy of artificial life strongly differs from traditional modeling by studying not only “life-as-we-know-it” but also “life-as-it-might-be”." https://lnkd.in/eE92tBk View in LinkedIn

ARTIFICIAL LIFE, as it is called, has contributed a very critical element to our knowledge of many things. But most of all, the concept that natural unguided processes of mutation, selection, and evolution can be far more creative than evolution that is man-made or directed. Nature appears to have an unlimited and unfettered creativity. This is the true gift of work on artificial life. View in LinkedIn

VIRTUAL CREATURE EVOLUTION is a spooky glimpse into the world of binary code generating artificial virtual genotypes and phenotypes that can be bred and compete among each other on some crude Darwinian principles. View in LinkedIn

VARIANT INFERENCE. “These characteristics may render such changes more statistically probable, less likely to be deleterious, or both. However, most non-canonical genetic codes are inferred from DNA sequence alone, or occasionally DNA sequences and corresponding tRNAs.” https://lnkd.in/d87ZWbH View in LinkedIn

INSPIRATIONAL. "Sims’ work has inspired several other works on three-dimensional virtual creatures." https://lnkd.in/dW4WdiC View in LinkedIn

RARE EVENTS. “This may be a true reflection of natural diversity of the code, because stop codons are by definition rare (only one of three possibilities appearing per gene, whereas even rare amino acids are typically found many times) and the fidelity of termination is potentially less critical than other possible changes.” https://lnkd.in/d87ZWbH View in LinkedIn

DEVIANT CODES. “The evolutionary mechanisms that lead to codon reassignment and emergence of deviant codes involve changes in tRNA specificity and/or evolution of new specificities in the case of stop codon recruitment.” https://lnkd.in/dKTqJpY View in LinkedIn
