The principle of mutability is the notion that any physical property which appears to follow a conservation law may undergo some physical process that violates its conservation. [ 1 ] [ 2 ] [ 3 ] John Archibald Wheeler offered this speculative principle after Stephen Hawking predicted the evaporation of black holes which violates baryon number ...
In the theory, mutation was the source of novelty, creating new forms and new species, potentially instantaneously, [1] in sudden jumps. [2] This was envisaged as driving evolution, which was thought to be limited by the supply of mutations.
The stability–instability paradox is an international relations theory regarding the effect of nuclear weapons and mutually assured destruction.It states that when two countries each have nuclear weapons, the probability of a direct war between them greatly decreases, but the probability of minor or indirect conflicts between them increases.
The French Transformisme was a term used by Jean Baptiste Lamarck in 1809 for his theory, and other 18th and 19th century proponents of pre-Darwinian evolutionary ideas included Denis Diderot, Étienne Geoffroy Saint-Hilaire, Erasmus Darwin, Robert Grant, and Robert Chambers, the anonymous author of the book Vestiges of the Natural History of ...
Adaptive mutation, also called directed mutation or directed mutagenesis is a controversial evolutionary theory. It posits that mutations, or genetic changes, are much less random and more purposeful than traditional evolution, implying that organisms can respond to environmental stresses by directing mutations to certain genes or areas of the genome.
A newer theory suggests that the selective pressure on the CCR5 Delta 32 mutation was caused by smallpox instead of the bubonic plague. [ 116 ] Malaria resistance : An example of a harmful mutation is sickle-cell disease , a blood disorder in which the body produces an abnormal type of the oxygen-carrying substance haemoglobin in the red blood ...
The Indonesian Wikipedia (Indonesian: Wikipedia bahasa Indonesia, WBI for short) is the Indonesian language edition of Wikipedia.
