What answer choice best describes Macroevolution? Evolution that focuses on changes between different species. The adaptation of a species to its new environment. The formation of a new organ within a species. Evolution that affects large animals ONLY.

## Step 1<br />Macroevolution refers to the evolution that occurs at or above the species level. This means it involves changes that affect large groups of organisms, such as different species or even larger groups like families, orders, or classes. <br /><br />## Step 2<br />The other options provided do not accurately describe macroevolution. <br /><br />## Step 3<br />Option B describes adaptation, which can be a result of both microevolution (changes within a species) and macroevolution, but it is not specific to macroevolution.<br /><br />## Step 4<br />Option C describes the formation of a new organ, which is a specific type of change that can occur due to evolution but does not define macroevolution.<br /><br />## Step 5<br />Option D is incorrect because macroevolution does not specifically affect large animals only; it can affect any group of organisms.
