What is an example of Macroevolution? The formation of new species or higher taxonomic groups over long periods of time. The sudden appearance of a new species without any gradual change. The change in the size of a population over a short period of time The development of new organs within a single generation.

## Step 1<br />Macroevolution refers to the formation of new species or higher taxonomic groups over long periods of time. This process involves significant changes that occur at or above the species level, leading to the formation of new species or groups of species. These changes are usually the result of long periods of time, often spanning thousands or millions of years.<br /><br />## Step 2<br />The other options provided do not accurately describe macroevolution. The sudden appearance of a new species without any gradual change is not macroevolution, as macroevolution involves gradual changes over a long period of time. The change in the size of a population over a short period of time is a characteristic of microevolution, not macroevolution. The development of new organs within a single generation is also a characteristic of microevolution, not macroevolution.
