What are darwin.

Darwin’s observations that led to his theory of natural selection are: Overproduction – all species will produce more offspring than will survive to adulthood. Variation – there are variations between members of the same species. Adaptation – traits that increase suitability to a species’ environment will be passed on.Darwin's theory. During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galápagos.He had learned how to preserve bird specimens from John Edmonstone while at the University of Edinburgh and had been keen on shooting, but he had no expertise in ornithology and by this stage of the voyage concentrated mainly on geology.

Darwinism, when it was first put into the lexicon by Thomas Huxley in 1860, was only meant to describe the belief that species change over time.
