Based on what you've learned about natural selection and the evolution of traits, what do you think happened to the beaks of the finches? How did you make this hypothesis? What existing knowledge formed your opinion?

Respuesta :

Over time the breaks of the finches will evolve and change in order to accommodate the changing habitats and survive.

Evolution:

  • Evolution is defined as the change in the inherited traits of a population of organisms through successive generations. When living organisms reproduce, they pass on to their progeny a collection of traits.
  • It's types include: Natural selection, random genetic drift, mutation, population mating structure, and culture.

The evolution of traits to beaks of the finches:

  • Beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti.
  • Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits. Shorter, stouter beaks served best for eating seeds found on the ground.
  • The shape of a bird's beak is an inherited trait.
  • Different bird species have differently shaped beaks because each species has evolved a beak design that suits its diet and lifestyle.
