Darwin's finches an iconic adaptive radiation
WebKey points: Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor. The mechanism that Darwin proposed for evolution is natural selection. WebFeb 1, 2024 · Craniofacial evolution in Darwin’s finches and Hawaiian honeycreepers seems to be characterized by a tighter coevolution of the beak and the rest of the skull than in most landbird lineages, with rapid and extreme morphological evolution of both skull regions along constrained directions of phenotypic space.
