PRECISE EDITING. "It is becoming increasingly evident that the driving forces of evolutionary novelty are not randomly derived chance mutations of the genetic text, but a precise genome editing by omnipresent viral agents." An extraordinary statement to wrap your mind around, and contrary to previous thinking. Re-read and re-digest. https://lnkd.in/e-pJFM6 View in LinkedIn

RANDOM MUTATIONS, or more recently, horizontal gene transfer, have been widely considered to be the primary driver of genetic diversity, and with that diversity, a richer toolbox for selective evolutionary pressures to squeeze out newly adapted genomes and creatures from the edges of their Bell Curves.

2ND ASSUMPTION. "The contribution to this number of sequences by viral and eukaryotic genomes is difficult to estimate but it is very unlikely to be orders of magnitude greater than the 4×10(43) sequences from bacteria. If their contribution is similar or smaller, then it can be ignored in our rough calculation." https://lnkd.in/eyPrQUq View in LinkedIn

TRADE-OFF. "The majority of the new viral mutations are deleterious to the virus from a natural selection perspective. Was the high mutation rate of viruses a trade off for selection for faster replication rates?" Faster replication rates afforded the ability to evolve more rapidly and adapt to new niches faster. https://lnkd.in/e9KGgbm View in LinkedIn

2ND ASSUMPTION. "Let us assume that every single gene in this total of 10(34) is unique and that evolution has been working on these genes for 4 Gyr completely changing each gene to some other unique, new gene every single year. This gives an extreme upper limit of 4×10(43) different amino acid sequences explored since the origin of life." https://lnkd.in/eyPrQUq View in LinkedIn
