Which rock layer most likely contains fossils of the most recently evolved organisms? (see picture)

The rock layer which most likely contains fossils of the most recently evolved organisms is: A. 1'

A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in an ascending order, usually from the youngest layer to the oldest.

Generally, rock layers that are found in various parts of the world are different because they all comprises distinct Earth's geological history referred to as fossils.

A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.

This ultimately implies that, ancient organisms such as plants and animals formed into rocks that are known as fossils.

Based on the geologic column (diagram), the rock layer which most likely contains fossils of the most recently evolved organisms is layer 1 because the youngest fossils sits on top while the oldest fossils are in layer 4.
