The correct answer is C. When two species separated from a shared ancestor

Explanation:

In biology, the term "molecular clock" refers to a technique biologist use to study the origin of mutations that made one; species led to others. This implies through the molecular clock scientist can determine the evolution and species and the time in which two species separated from a shared ancestor or diverged. This technique relies mainly on biomolecular information based on sequences of DNA as differences in DNA between two species with a common ancestor marks the divergence of these species, also molecular clocks use the comparison of fossils to confirm evolutive divergence. Therefore, it can be concluded biologist use molecular clocks to try to measure "when two species separated from a shared ancestor".

Explanation:

The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:

They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.
