Oak
Explanation:
Based on the fossil arrangement, we can deduce that the oak was the first to evolve of all the listed fossils.
Fossils are the preserved remains of organisms usually found in rock layers.
To predict the age of fossils, we use one of the principle of relative dating.
The most appropriate one proposed by Williams Smith is the principle of fossil and fauna succession.
It states that "fossils and fauna succeed one another in relative pattern as they evolve".
- The first fossil to evolve will be the oldest one and it will be located at the base of the sequence.
- This is why the choice is oak.
