Таҳаввул (русӣ: эволюция аз лот. evolutio — «густариш») — раванди табиии инкишофёбии табиати зинда, ки бо тағйирёбии таркиби генетикии популятсияҳо, ташаккули мутобиқшавӣ, ҷинспайдошавӣ ва нобудшавии намудҳо, дар маҷмӯъ табдилёбии экосистемаҳо ва биосфера мебошад.^[1]

Таҳаввул — тағйирёбии табии хусусиятҳои ирсии популятсияи биологӣ дар наслҳои оянда мебошад.^[2]^[3] Ин хусусиятҳо ифодаи генҳоест, ки ҳангоми афзоиш аз волидайн ба насл мегузаранд. Хусусиятҳои гуногун дар дохили ҳар як популятсия одатан дар натиҷаи мутатсия, рекомбинатсияи генетикӣ ва дигар манбаъҳои тағйирпазирии ирсӣ, мавҷуд мебошанд.^[4]

Таҳаввул вақте рух медиҳад, ки равандҳои таҳаввулотӣ ба монанди интихоби табиӣ (аз ҷумла интихоби ҷинсӣ) ва дрейфи генетикӣ ба ин тағйирпазирӣ таъсир мерасонанд, ки дар натиҷа хусусиятҳои муайян дар дохили популятсия бештар паҳн ё нодир мешаванд.^[5] Маҳз ҳамин раванди таҳаввулот гуногунии биологиро дар ҳама сатҳҳои ташкилоти биологӣ, аз ҷумла сатҳи намудҳо, организмҳои инфиродӣ ва молекулаҳо, ба вуҷуд овард.^[6]^[7]

Назарияи илмии таҳаввул бо интихоби табиӣ аз ҷониби Чарлз Дарвин ва Алфред Рассел Уоллес дар нимаи асри 19 мустақилона таҳия карда шуд ва дар китоби Дарвин дар бораи пайдоиши намудҳо (1859) муфассал баён карда шудааст.^[8]

History of evolutionary thought

Lucretius

Alfred Russel Wallace

Thomas Robert Malthus

In 1842, Charles Darwin penned his first sketch of On the Origin of Species.^[9]

Classical times

Medieval

Pre-Darwinian

Darwinian revolution

Pangenesis and heredity

The 'modern synthesis'

Further syntheses

Heredity

DNA structure. Bases are in the centre, surrounded by phosphate-sugar chains in a double helix.

Variation

Black morph in peppered moth evolution

Mutation

Duplication of part of a chromosome

Sex and recombination

Gene flow

Mechanisms

Mutation followed by natural selection results in a population with darker colouration.

Natural selection

Genetic hitchhiking

Genetic drift

Simulation of genetic drift of 20 unlinked alleles in populations of 10 (top) and 100 (bottom). Drift to fixation is more rapid in the smaller population.

Gene flow

Mutation bias

Mutation bias is usually conceived as a difference in expected rates for two different kinds of mutation, e.g., transition-transversion bias, GC-AT bias, deletion-insertion bias. This is related to the idea of developmental bias.

Outcomes

A visual demonstration of rapid antibiotic resistance evolution by E. coli growing across a plate with increasing concentrations of trimethoprim.^[10]

Adaptation

Lua error in Модул:Details at line 30: attempt to call field '_formatLink' (a nil value).

Homologous bones in the limbs of tetrapods. The bones of these animals have the same basic structure, but have been adapted for specific uses.

Coevolution

Common garter snake (Thamnophis sirtalis sirtalis) has evolved resistance to the defensive substance tetrodotoxin in its amphibian prey.

Cooperation

Speciation

The four geographic modes of speciation

Extinction

Tyrannosaurus rex. Non-avian dinosaurs died out in the Cretaceous–Paleogene extinction event at the end of the Cretaceous period.

Social and cultural responses

As evolution became widely accepted in the 1870s, caricatures of Charles Darwin with an ape or monkey body symbolised evolution.^[11]
