1. The process by which one state changes into another. Anything which is not static evolves over time. The word evolution specifically excludes any connotation of improvement or progress, so even 'negative' changes are evolution. In biology, this definition is often observed in terms of the change of gene frequencies in natural populations. There is no controversy about this definition.
2. The theory that species give rise to other species. This process of speciation can be accomplished in a number of ways, all of which must result in two (or more) populations becoming genetically isolated. This can be accomplished physically (allopatry and peripatry) or through division of patch types or through behavioral mechanisms (sympatry). This has been observed at low taxonomic levels. For instance, wheat is a modern species resulting from 2 instances of non-disjunction and one hybridization event that all occurred within the last 5000 years. The original plant has been identified from seeds from tombs in Egypt.
The creation of new higher level taxa is often referred to as macroevolution by non-scientists, but this usage is incorrect. The only difference between the origins of higher taxa and species is time. Today's species will eventually give rise to genera as they continue to diverge from their sister-taxa and continue to speciate themselves. All higher taxa were once just a species. Macroevolution properly refers to selection that operates above the species level, such as the selective pressure across the K-Tboundary on gastropods which favored genera (but not species) with wide geographic ranges.
I'll note that theory is the most certain science ever is. In this case, it means that over the last century and a half, plus the observations from before the theory's proposal, no evidence has been found that contradicts the theory of evolution. By the same token, gravity is a theory, and thermodynamics is a theory. 'Law' is just scientific shorthand for a theory that no one thinks will ever be disproved, and may soon be applied to evolution.
1. The reaction was in a critical phase of its evolution.
2. The fossilsequence of horses is an excellent example of evolution
A popular haunt for (cockmasters). Possibly the greatest nightclub on planet Earth. Whether it be vodka on a Thursday or jelly baby on a Saturday, there's no place like Evo.
A nightclub in Bristol where post-townie single mums and office girls congregate to consume vast quantities of alcohol as preparation for the next days paid sick leave. Often used as an alternative to a social life when one is unavailable.
A scientific theory that all life on earth descended from a common ancestor. Evolution has been repeatedly proven and observed time and time again, yet most of the morons writing definitions for Evolution on urbandictionary.com choose to ignore that.
Average Creotard/Mentally retarded redneck: Evolution b'aint be reel cuz dat der bibl tingy be sayin' su!
affiliate it'self with nonbiological or non-self replicating matter such as boeing 747s and scrap
allow its self to be defined by the majority of the definitions on the first few pages
hate you (but I might)
comment any anyting remotly metaphysical like the soul
That just about ruels most of the top rated definitions, and that is my point, find out what evolution is before considering yourself in a position to define it. On the subject of irriducable complexity. here's a laman's guide to the evolution of the eye:
An organism developes a cell/cluster of cells sensitive to light through a random mutation, this allows the organism to distinguish between being in light and dark, giving it a few obviouse advantages over it's competing organisms.
This then developes into a line of cells, giving the population the advantage of detecting the direction this light is coming from.
The line then becomes gradually more concave as the spicies developes, giving it more and more sense of directon of the light.
the cells then concave to the point of being a ball with a 'biological appature' allowing the spicies to eventually see basic images.
the cells then evolve to detect different wavelenghts of light (colour) ect. ect.

Doesn't Evolution say we call come from monkeys?
No.
Doesnt Evolution say that all the dirt in the universe was condensed into a region smaller than a period at the end of this sentence?
Absolutly fucking not!!! EVER!!!!!
XXXTENTACION : You evolute in mind, you evolute as far as your age, you evolute physically .. mentally. If you are evoluting physically and you are not evoluting mentally, you are not doing the right thing.
