Abstract

In physical terms life constitutes a complex carbon -based system which replicates information, departs from thermodynamic equilibrium through the use of chemical metabolism , and undergoes variation and selection . Living things tend to be complex and highly organized, have an ability to acquire energy from the environment and transform it for growth and reproduction , tending toward homeostasis , response, stimulation, reaction, recoiling, learning, reproduction , growth and development. A phylogenetic scheme is based upon ribosomal RNA sequence which shows living systems belong to one of three classes: (A) the eubacteria , comprising all typical bacteria ; (B) the archaebacteria , containing methanogenic bacteria ; and (C) the Eukaryotes, comprising cytoplasmic components within eukaryotic cells from which species and kingdoms evolved. Evolving cell network emerge as output of a cellular computing network , inducing changes in structure of the network itself through changes in the DNA activity patterns. In an “RNA world ” self-replication is reached by combination of the nucleotides adenine , uracil, guanine and cytosine , forming templates for synthesis of new strands of RNA . Early cells formed by enclosure of self-replicating RNA in membrane composed of phospholipids , the basic components of biological membranes of prokaryotic and eukaryotic cells. The DNA of Eukaryote cells may contain 0.6–5.0 × 106 base pairs, capable of encoding about 5000 different proteins. Given the distinct structure and composition of the cell and computer chips, both possessing high processing power and natural and artificial intelligence , respectively, the design of artificial intelligence offers insights into some of the processes taking place in natural systems. The exploration of the deep hot biosphere located in oceanic hydrothermal energy sources, or within fractures in deep seated rocks, isolated from the influence of the sun and photosynthesis , has opened new windows in the search for early evolution of life . The development of colonies consisting of specialized cells signifies emergence of inter-cellular communications and coordination, implying each cell possess information regarding what the other cells are doing—a quantum leap toward evolution of complex multi-task organisms .

Superstrings

Tiny wispy strings

Cryptic little things

Shape universes, sing

Oh take me on your wings.

X-apparitions chase

Light speed - a cosmic race

Appears from quantum space

Oblivious to my race.

DNA chains extend

RNA healers bend

Repair a link, append

life’s wonder: self-amend.

RNA chains collapse

A lover’s final gasp

Queen Cleo’s sacrifice

While gods are playing dice.

Unseen hands strum guitar

Bells’ echoes reach afar

No strings attached, no bar

Can bind a young blue star.

My thought waves rise and ebb

Brains weave a spider’s web

Probe truths or make believe

Loft crests I can’t achieve.

Web sites each other find

A net’s collective mind

Tripwire humankind

A cyclops stumbling blind.

    A chromosome is a DNA molecule with part or all of the genetic material (genome ) of an organism . Chromosomes, which carry the hereditary material, or DNA , are contained in the nucleus of each cell . Chromosomes come in pairs, with one member of each pair inherited from each parent. The two members of a pair are called homologous chromosomes. Each cell of an organism and all individuals of the same species have, as a rule, the same number of chromosomes. The reproductive cells (gametes) are an exception; they have only half as many chromosomes as the body (somatic) cells. But the number, size, and organization of chromosomes varies between species .

    Ribozymes (ribonucleic acid enzymes) are RNA molecules that are capable of catalyzing specific biochemical reactions, similar to the action of protein enzymes.

    An emergent property is a property which a collection or complex system has, but which the individual members do not have. A failure to realize that a property is emergent , or supervenient, leads to the fallacy of division. An emergent behavior or emergent property can appear when a number of simple entities (agents) operate in an environment, forming more complex behaviors as a collective . If emergence happens over disparate size scales, then the reason is usually a causal relation across different scales.

    At its most basic level, the concept of emergent properties states that with rising levels of complexity in living things, new patterns will emerge. This is the case whether you move up the chain from simple single-celled organisms to much more complex multi-celled organisms , or whether you move from a single organism to an entire population of that organism . http://education.seattlepi.com/emergent-properties-living-things-biology-6131.html.
