Answer:
a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape,2 (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
Galalpagos Island finches have different shaped beaks which can consume different foods. The more food sources a number of species can tap into, the less scarcity they have to deal with within one--less competition, more food overall...and if that certain genetic trait helps a finch survive, that trait is going to be perpetuated by its offspring. (natural selection)
