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.
Journal ArticleDOI
Hybridization of Bird Species
Peter R. Grant,B. Rosemary Grant +1 more
TL;DR: A longitudinal study of Darwin's finch populations on a Gal�pagos island shows that hybrids exhibit higher fitness than the parental species over several years, and may be at an occasional disadvantage for ecological rather than genetic reasons in this climatically fluctuating environment.
