1. Hawaiian honey-keepers are a group of birds with similar body shape and size. However, they very greatly in color an beak shape. each species occupies its own niche and is adapted to food available in its niche. The evolution from a common ancestor to a variety of species is an example of:
a. divergent evolution
b. convergent evolution
c. artificial selection
d. inbreeding
2. The flying squirrel of North America closely resembles the flying phalanger of Australia. they are similar is size and have long, bushy tails and skin folds that allow them to glide through the air. The squirrel is a placental mammal while the phalanger is pouched mammal. Their resemblances, even though genetically and geographically separated by huge distances, can best be explained by:
a. divergent evolution
b. convergent evolution
c. artificial selection
d. inbreeding

Biology Question, Can Some One Help Me?
Posted on October 18, 2010.
1. A) Basically, these birds have DIVERGED from the original species. These tends to happen when there is a decrease in predators and competition. These birds were originally competing, but as time passed some of these birds were born with different beak shapes and color. This led to eating slightly different foods. Over time, as competition decreased more, the foods varied more and more so that they no longer competed for the same types of food
2. B. While these species do no share a lineage, they share a similar environment. Remember that evolution is just a change in one’s genes as a result of a changing environment. If two species from different parts of the world happen to be exposed to similar circumstances over a period of time, they may change in similar ways to deal with that problem.
e. evolution is a lie.
