Traditional choice is greater than the survival of the fittest: it's a strength engendering larger organic complexity. providing a brand new cause of the tendency of lifestyles to turn into extra complicated via evolution, this publication deals an creation to the most important debates in evolutionary idea, together with the function of genes and intercourse in evolution, the adaptive purposes for senescence and loss of life and the beginning of neural details. the writer argues that organic complexity elevated throughout the strategy of 'modularity transfer': modular phenotypes (proteins, somatic cells, realized behaviours) advanced into new modular details vendors (regulatory proteins, neural cells, words), giving upward push to new details platforms and better degrees of organic company. Modular Evolution is smart of the original position of people in evolution, either because the top of organic complexity and inventors of non-biological evolution.

The definition also excludes various codes proposed by Barbieri (2003), such as a ‘histone code’ or the ‘sugar code’, which are different ways of transmitting the ‘same’ type of information. A further consequence is that since the evolution of a new biological code relies on a previously existing one, a functional and evolutionary hierarchy is established between them. Barbieri (2003) pointed out that new organic codes do not replace previous ones, but the hypothesis that a new code derives from transformation of a previously existing phenotypic entity implies more than that: it implies that the previous code cannot disappear.
Examples of new ways of transmitting information include the origin of template replication, the genetic code, developmental and epigenetic regulation, and human language. The theory of major transitions has the merit of defining evolutionary increases in complexity both at the phenotypic-organisational (the newly evolved super-units) and genotypic-informational (the new methods of transmitting biological information) levels. A second advantage is that it avoids anthropocentric criteria of complexity.
Thus, transcription factors, neural cells and brains, behaviour and cognition, and human language all derived their modular The evolution of order organisation from previously existing disposable, modularly organised phenotypic entities. , 2000) are central concepts in evolutionary studies, but tend to be treated separately. The evolutionary formulation of Schrödinger’s Principle of Order from Order and the concept of modularity transfer unify those debates to a certain extent. All the biological codes are different manifestations of Schrödinger’s Principle of Order from Order: they are ways in which different types of microscopic order or information is converted into different forms of macroscopic or phenotypic order.
