Question

multiple choice question
molecular, fossil, and anatomical evidence indicates that birds are a type of

o amphibian.
o flying arthropod.
o mammal.
o reptile.

Explanation:

Molecular, fossil, and anatomical evidence shows that birds share a common evolutionary origin with reptiles. For example, some dinosaur fossils (which are reptiles) have feather - like structures, and there are genetic and anatomical similarities between birds and reptiles. Amphibians have different life - cycle (e.g., metamorphosis from water - living larva to land - living adult) and anatomical features (e.g., moist skin for gas exchange). Flying arthropods (like insects) have an exoskeleton and a different body plan. Mammals have features like hair and mammary glands which are not present in birds.

Answer:

reptile.
