Question

Quizplus · Accepted Answer

Since the question mentions that the physical appearances of the two bird fossils are different, it is unlikely that they would belong to the same species. Therefore, classification based on the biological species concept (A) or evidence of reproduction (D) would not be useful. While DNA analysis (B) can provide valuable information for species identification, it may not always be possible for fossils that are millions of years old. Morphology (C) refers to the physical characteristics of organisms and is commonly used in paleontology to classify species based on their physical features. Therefore, it is the most likely method that scientists would use to classify these bird fossils.
