WebFrom Grant, 1991. Darwin's finches share common features of nest architecture, egg pattern, and courtship displays. They differ in song, morphology, and plumage. Based on morphology, allozyme, and DNA sequence data, the warbler finch C. olivacea appears to be closest to the ancestral form. WebEvolution in Darwin’s finches is characterized by rapid adaptation to an unstable and challenging environment leading to ecological diversification and speciation. This has resulted in striking diversity in their phenotypes (for instance, beak types, body size, plumage, feeding behavior and song types). Beaks are one of the most diversified ...

WebJun 5, 2013 · Darwin worked with no knowledge of genetics, but in terms of today’s science his educated guess was exactly right. Darwin’s finches (subfamily Geospizinae) exist in 14 or 15 monophyletic species—monophyletic meaning that all species of Galápagos finches evolved from one species. This happened two million or more years ago. WebThe Museum's Library holds the world's largest concentration of Darwin works.

Darwin's finches (also known as the Galápagos finches) are a group of about 18 species of passerine birds. They are well known for their remarkable diversity in beak form and function. They are often classified as the subfamily Geospizinae or tribe Geospizini. They belong to the tanager family and are not closely related to the true finches. The closest known relative of the Galápagos finches is the So… WebApr 1, 2001 · Ecology and Evolution of Darwin's Finches.—Peter R. Grant. 1999.
