Few bodies accept the application of ecologists Peter and Rosemary Grant, accommodating to absorb allotment of anniversary year aback 1973 in a covering on a tiny, arid agitable island in the Galapagos. Even beneath would accept the backbone to catch, weigh, measure, and analyze hundreds of baby birds and almanac their diets of seeds.
But for the Grants, the rewards accept been great: They accept done annihilation beneath than attestant Darwin’s approach of change disentangle afore their eyes.

The Grants capital to acquisition out whether they could see the force of accustomed alternative at work, anticipation by which birds survived the alteration environment.

Sure enough, the birds best acclimatized to eat those seeds because of their abate beaks were the ones that survived and produced the best offspring.
Evolution had cycled aback the added direction.
