Book
Ecology and evolution of Darwin's finches
TL;DR: This book is the classic account of how much the authors have since learned about the evolution of Darwin's Finches and shows how interspecific competition and natural selection act strongly enough on contemporary populations to produce observable and measurable evolutionary change.
Journal ArticleDOI
Unpredictable evolution in a 30-year study of Darwin's finches.
Peter R. Grant,B. Rosemary Grant +1 more
TL;DR: Continuous, long-term studies are needed to detect and interpret rare but important events and nonuniform evolutionary change in Darwin's finches on the Galápagos island of Daphne Major.
Journal ArticleDOI
Evolution of Character Displacement in Darwin's Finches
Peter R. Grant,B. Rosemary Grant +1 more
TL;DR: It is reported that a Darwin's finch species on an undisturbed Galápagos island diverged in beak size from a competitor species 22 years after the competitor's arrival, when they jointly and severely depleted the food supply.
Journal ArticleDOI
Evolution of Darwin’s finches and their beaks revealed by genome sequencing
Sangeet Lamichhaney,Jonas Berglund,Markus Sällman Almén,Khurram Maqbool,Manfred Grabherr,Alvaro Martinez-Barrio,Marta Promerová,Carl-Johan Rubin,Chao Wang,Neda Zamani,B. Rosemary Grant,Peter R. Grant,Matthew T. Webster,Leif Andersson +13 more
TL;DR: The whole-genome re-sequencing of 120 individuals representing all of the Darwin’s finch species and two close relatives finds extensive evidence for interspecific gene flow throughout the radiation.
Journal ArticleDOI
Bmp4 and morphological variation of beaks in Darwin's finches.
TL;DR: A comparative analysis of expression patterns of various growth factors in species comprising the genus Geospiza found that expression of Bmp4 in the mesenchyme of the upper beaks strongly correlated with deep and broad beak morphology.
