Variation exists within all populations of organisms.

This occurs partly because Dating northwest Darwin mutations arise in the genome of an individual organism, and offspring can inherit such mutations. Throughout the lives of Dating northwest Darwin individuals, their genomes interact with their environments to cause variations in traits.
The environment of a genome includes the molecular biology in the cellother cells, other northwet, populations, Men in black Bentleigh Eastas well as the abiotic environment.
Because individuals with certain variants of the trait tend to survive and reproduce more than individuals with other, less successful variants, nortnwest population evolves. Other factors affecting reproductive success include sexual selection now often included in natural selection and fecundity selection. Natural selection acts on the phenotype, the characteristics of the organism which actually interact with the environment, but the genetic heritable basis of any phenotype that gives that phenotype a reproductive advantage may become more common in Datin population.
Over time, this process can result in populations that specialise for particular ecological niches microevolution and may eventually result in speciation the emergence of new species, macroevolution.

These crucial observations, combined with his study of Lyell's Principlesprepared Darwin's mind for a break with received wisdom on species origins, as he himself stated in the opening lines of Origin and as he explained with great clarity in the introduction to Variation Ocean massage Rockhampton 9ff.
There were, however, many other observations made by Darwin during the voyage which contributed to his eventual development of evolutionary theory, including, for example, the mammals of the Falklands and Ascension Island, the absence with a few minor exceptions Dating northwest Darwin indigenous mammals on New Zealand, the antlion of Australia and the dramatic differences between Englishmen and Fuegians.
