Question

what does natural selection have to do with diversity?
what does the case of seed availability and natural selection tell us about how diversity might have emerged on the galapagos?
different islands may have had different foods that affected the hormones in finches, causing them to develop new traits. birds with these new traits became a new species.
different islands may have had different food sources that required different physical structures to eat, giving those finches with favorable physical traits an advantage. these \favored\ individuals developed into a new species.
the animals on the islands of the galapagos have always looked the way that they do, since the beginning of time.
different food sources on the different islands have caused some traits to be more common than others but cannot create a new species.
once the food source on an island changes, the organisms that can eat the new food source will develop into a new species in as little as a year. those that cant eat the new food die out.

Explanation:

Natural selection acts on variations in a population. In the Galapagos, different food sources on islands meant finches with physical structures (traits) suitable for accessing those foods had an advantage. Over time, these favorable - trait - bearing finches could develop into new species, contributing to biodiversity.

Answer:

B. Different islands may have had different food sources that required different physical structures to eat, giving those finches with favorable physical traits an advantage. These "favored" individuals developed into a new species.
