Over the past several years, the concept of natural genetic engineering > has been advanced to encompass biochemical functions that make up the cellular toolbox for changing genome sequence composition and organization. Natural genetic engineering activities range from the introduction of point mutations by mutator polymerases to large-scale chromosome rearrangements mediated by transposable elements and non-homologous end-joining to incorporation of viral and microbial DNA into the genomes of host organisms.

"Glance at Witzany's little book and put it beside standard texts on semio-communication written by those who still favour mechanistic causality in exploring animal behaviour and you can see how far Biosemiotics has come" (Peter Harries-Jones, University of Toronto)

To know the “molecular syntax” (Manfred Eigen) of the genetic sequences of organisms doesn’t mean to know all “multiple protein meanings” (Gil Ast) that derive from a great variety of higher-order regulatory functions hidden in the non-protein-coding DNA. The network of higher-order regulatory functions and its important role to the key processes in DNA replication and recombination is now being recognized as a complex hierarchical pattern. This includes also the highly dynamic patterns of genome formatting as prerequisite to the great variety of epigenetic processes as demonstrated by Randy Jirtle at the Biosemiotic Congress 2006 in Salzburg.

The conditions on the surface of a planet without living organisms are determined entirely by the sun's energy and the laws of physics and chemistry, as James Lovelock showed convincingly (Margulis, 1999).
A planet with living organisms deviates considerably from this scheme. The gas composition and temperature will vary in a manner that cannot be predicted exclusively by the laws of physics and chemistry alone. Such a planet contains incompatible gas mixtures and temperatures whose relatively stable balance is actively controlled by organisms...

It’s life, but just as we know it

…to decide who is first in the ‘race to create life’ requires a consensus definition of life
Both the genetic code and all computerprogramming languages are means of communicating large quantities of codified information, which adds another element to a comprehensive definition of life.

A milestone edition that for the first time comprehensively presents the exciting topic of soil biocommunication. A valuable source of information for scientists in microbiology, biochemistry, genetics and soil ecology.

Guenther Witzany, an Austrian philosopher, has developed a “theory of communicative nature” that, he claims, differentiates biotic and abiotic life. “Life is distinguished from non-living matter by language and communication,”
