Hyper-Plastic Structural Evolution Of The PEX Domain - A Model Of Evolutionary Exaptation And Neofunctionalization At The Molecular Level
With the advent of sophisticated genetic, biophysical and in silico technology an enormous amount of information is being generated regarding the structural, biochemical and physiological aspects of proteins. Tertiary protein structural domains are assumed to be features of proteins whose …

Mobile genetic element contribution to the genome architecture of the human parasitic flatworm Schistosoma mansoni
… genes via transposition in a process known as exaptation and stimulating recombination, particularly between subtelomeres. These regions are repeat-rich, prone to repeat element-mediated recombination and, in other organisms, harbour genes associated with parasite proliferation, invasion, and …

Hyperadaptation - Another Missing Term in the Science of Form
… term in the science of form, which they call 'exaptation'. In the present project, I show that evolutionary biology still contains a confusion in the use of 'adaptation' due to an inappropriate perception of the interaction between the two components of adaptation. Because of the confusion, …

Mammalian-wide interspersed repeats (MIRs) and their role in mammalian gene function and evolution
… into RNA and inserted into the genome as DNA. Exaptation of these elements can provide additional or novel function for endogenous genes. Mammalian-wide interspersed repeats (MIRs) are short interspersed nuclear elements (SINEs), belonging to the non-autonomous class of retroelements and are …

The ecomorphology of facultative bipedality in Lepidosauria: implications for the evolution of reptilian bipedality
… indicating that facultative bipedality is an exaptation of anatomies associated with vertically diverse environments. This echoes the evolution facultative bipedality in hominin, macropods and rodents, and is distinct from any current hypotheses concerning the evolution of archosaurian …

The study of ancient viral class II envelope fusion proteins within the viral retroelements of Nematoda and the nuclear plasmids of Dictyostelium
… this evidence points to a novel case of gene exaptation. Similarly, class II fusion homologues have been identified within the double-stranded, circular, nuclear plasmids of the slime mold Dictyostelium. While these plasmids, specifically Ddp1 and Ddp5, have been used as transfer vectors in …

UN INCONTRO TRA DARWINISMO E PRAGMATISMO: LA FILOSOFIA EVOLUZIONISTICA DI CHAUNCEY WRIGHT
… as they call this transformational principle, “exaptations”, in order to go beyond an “adaptationist” or “panselectionist” interpretation of the Darwinian theory. This pluralistic view, as a working hypothesis, is very effective in its approach to the theoretical problems, especially when Wright …
