Question

Identify the most suitable option.
Fossil X is older than fossil Y because
A. Fossil X was found in deeper sedimentation
B. Fossil Y was found in deeper sedimentation
C. Fossil Y has homologous and analogous organs of X
D. Fossil Y has some vestigial organs functional in X

Answer 1

Fossils are evidence of animal and plant life that has been preserved within the earth crust. Fossils can be actual parts of an animal or plant, or they can be traces of an animal such as its preserved footprints or even its preserved waste.

Complete answer:
Fossils are typically created when an animal or plant dies. Before it has a chance to decay, it is covered with sediment, which protects it from elements. As sediment builds up on top of the animal or plant it becomes hard form rock. Many of the fossils we find took place in a body of water. Over time the animal and plants remain washed away, leaving a mild of the remains.
it is relevant that one proof is rock layers explicitly, what is known as the geologic section. Fundamentally, scientists have discovered that stones are stacked in layers containing fossils with the most established fossils at the most profound layers. And the most youthful on the top.
So with the above explanation it is concluded that Option A is correct that Fossil X are found deeper sedimentation.

Note: Preserved traces of animals are important because they can reveal information about how the animal behaved long ago and what it ate. Presence of fossils in the ground tell us about their relative age.
