Answer:

Option (1)

Explanation:

According to the law of superposition, the rocks that are found at the bottom of an undisturbed sedimentary sequence are the oldest rocks as these layers are initially formed due to the process of deposition, sedimentation and lithification, and with progressive sedimentation, the rock layers that are formed at the the apex portion are the youngest rocks.

So, the fossils found in bottom rocks are the oldest fossils, and those fossils that are found in the top layer are considered to be the youngest fossils.

Thus, the oldest fossils are the ones that are found in the deepest strata.

Therefore, the correct answer is option (1).

Examples that show between species DNA show , and give evidence of evolution.
Mice21 [21]

Answer:

Evidence of evolution can be identified through fossil records, testimonial fossils, biography, anatomy, and embryology. An example of a species DNA is the peppered moth, whereby light-colored moths are eaten by birds, unlike the dark colored ones which seem to camouflage on dark backgrounds.  Evolution changes the genetic makeup of a population over time and may happen on a large scale or small scale basis which affects either one of a few genes over a short period.
