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.Abstract. Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America. Descendants of this ancestor on the …Key points: Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection.

Oct 19, 2023 · Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
