Consider the group of giraffes in the image below. which statement about the giraffes explains their evolution based on charles darwin’s main points? the closest fossil ancestor to these giraffes would have a very short neck. all three of the giraffes have an equal chance of reproducing regardless of the environment. as a giraffe reached for food, the giraffe could make its neck longer making it better adapted to the environment. long necks were a random genetic change and resulted in the gradual increase of organisms with long necks.

Long necks were a random genetic change and resulted in the gradual  increase of organisms with long necks.  

D.) Long necks were a random genetic change and resulted in the gradual increase of organisms with long necks.

i am positive it is c. condensing but i may be wrong

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
