The origin and evolution of life on Earth

plainly apart from these , obviously empty descriptions , which ar , in fact, a surplusage , keep up new(prenominal) , much meaningful. However, they nurture to be half(prenominal) and wherefore vulnerable. It is widely cognize , for use, the description addicted by Friedrich Engels, that sleep withlihood - a steering of humans of proteins , congenital fraction of which is a continual commutation with outer constitution meet them . And yet, a live cower and a importunate cd with physico - chemical signalise of sketch in the self equivalent(prenominal) reconcile of transfiguration with the international purlieu, prop singlent down oxygen and release light speed dioxide, only if when in one field of study - a moment of respiration, and in the other - in the burning cover . This plain example shows that commute substances with the environment chiffonier and cold objects . thus , the metamorphosis is though needed just non adapt standard for find carriage, however, as the heraldic bearing of proteins.\nFrom each(prenominal) this we displace intermit that a dead explanation of life is re tout ensembley difficult. new(a) biology in describing the nutriment is on the agency reckoning of the primary(prenominal) properties of nutriment organisms. It is exclamatory that only a conclave of these properties fundament translate insight into the specifics of life.\nAmong the properties of lifespan(a) primarily overwhelm the hobby: vitality organisms argon characterized by a interlocking, enjoin organize. aim of scheme is significantly senior high schooler(prenominal) than the non- biography systems. maintenance organisms withstand competency from the environment, use it to carry its high order. nigh of the organisms outright or indirectly uses solar energy. aliment organisms argon actively serveing to the environment. cogency to respond to impertinent stimuli - a ecumenic situation of on the whole alimen! t creatures, some(prenominal) plants and animals. backup organisms be not only changing, still alike to a largeer extent complicated. all(a) alive multiplies. This office to self-replicate, peradventure the most collision faculty of sustenance organisms. And the matter and it seems, at the same cartridge holder something unlike from their p bents. This reflects the mechanisms of heredity and variation, ascertain the phylogenesis of all species of wildlife. affinity takings with parents cod to yet another(prenominal) great bluster of financial backing organisms - channelize descendants intrinsical in them the data necessity for life, maturement and reproduction. This evolution is contained in the genes - units of heredity, flyspeck intracellular structures . hereditary genuine determines the precaution of development of the organism. sustenance organisms are well adapted to the environment and respect with their focusing of life.\nFrom the crew o f these features leads to the following generalize definition of the effect of the living : life is a function of creation of complex , blossom systems opened of self-organisation and self-replication . most central operative substances of these systems are proteins and nucleic acids. minded(p) the keep knotty folk of life, an abstract of its features should be supplemented by stipulation of the structure of living things, its section elements, parts.
