D

Verified step by step guidance1
Understand the context: Tetrapods are vertebrates with four limbs. The earliest tetrapods are significant in evolutionary biology as they represent the transition from aquatic to terrestrial life.
Identify key characteristics of early tetrapods: These organisms are known for having limbs with digits, which allowed them to move on land. This is a crucial adaptation for terrestrial life.
Evaluate the options: Consider which features are most likely to be present in the earliest tetrapods. Complex jaw structures and feathers are not typically associated with the earliest tetrapods.
Consider the evolutionary timeline: Feathers are more associated with birds, which evolved much later. Complex jaw structures are more characteristic of later vertebrates.
Conclude with the most likely characteristic: The presence of limbs with digits is a defining feature of early tetrapods, making it the most likely characteristic of the earliest tetrapod fossils.
