Darwin did not figure all of this out on his vacation. The truth is, he failed to even recognize many of the finches had been similar but distinct species until eventually he showed his specimens to a talented ornithologist (bird biologist) yrs later3 !
Above many generations, these designs of various survival and reproduction depending on beak condition (a heritable trait) could have induced a change in the typical beak form of each and every population. Particularly, the populace on the 1st island might have shifted in direction of a bigger, more durable beak on average, although the inhabitants on the second island may need shifted toward a thinner, sharper beak on ordinary.
