"The beaks of the Galapagos finches that Darwin observed evolved into multiple shapes, and each is adapted for what?"

Finch beaks were differentiated according to the different foods that each particular finch fed on.

Each finch developed in different zones and climax of the Galapagos island, that is why they were conditioned by the environment in which they lived, each particular environment made these finches adapt and evolve to be able to fulfill their life and not with extinction of the species.

This speaks of the evolution of species, how it adapted to environmental changes to survive, and how the fittest survive in the face of adversity.

Explanation:

Animals can have genetic modifications, which if they are inherited through generations and are optimal for the species is considered evolutionary processes of the species, beneficial for its survival.

Genetic changes are stimulated by environmental changes, and expressed with phenotypes, that is, with physical characteristics or qualities such as the different morphologies of finch beaks.

Each finch feeds on different sources, that is why those that eat hard insects will have more resistant beaks, those that have to remove the insect from the trees have more pointed beaks, those that grind seeds or fruits from the ground have more robust beaks and in the form of a "hook" for the possible crushing of the husk of the seed.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
