The Yellowstone fires of 1988 collectively formed the largest wildfire in the recorded history of Yellowstone National Park in the United States. Starting as many smaller individual fires, the flames quickly spread out of control due to drought conditions and increasing winds, combining into one large conflagration which burned for several months. The fires almost destroyed two major visitor destinations and, on September 8, 1988, the entire park closed to all non-emergency personnel for the first time in its history. In an average year, approximately 21 fires are ignited in Yellowstone by lightning. About 75% of fires in Yellowstone never reach more than 0.1 hectares (0.25 acres) in size
Only the last one provides an actual evidence of having a common ancestor. The rest can be a result of living in a similar environments that makes life easier. For example, many species live next to water, as water provides more fertile ground for plants, and they might have similar behaviors (searching for water) but they might not be closely related.
so the correct answer is D.
The correct option is C.
Living organisms that live in the littoral zones in the ocean are used to frequent changes in temperature and in the salinity of the ocean water. For an organism to survive in this environment, it needs to have adaptive features that will increase its survival. The littoral zone is divided into three zones, which are high, middle and lower littoral zones. Organisms living in high littoral zone have adaptive features that make them more adapted to desiccation due to the long hours of sunlight to which they are exposed. The organisms are usually exposed directly to the air or they can be enclosed in burrows.
Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier
