Answer:

a lunar eclipse

Explanation:

The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere.

notsponge [240]

A deficiency of dopamine is responsible for the signs and symptoms of Parkinson's disease.

Parkinson's disease is characterized by gradual degeneration of neurons in a section of the brain. In normal conditions, these neurons release a chemical substance known as dopamine which is important for the brain.

Dopamine is a neurotransmitter which facilitates communication amongst different parts of the brain that is responsible for smooth muscle activity and proper nerve operation.

Parkinson’s disease is a disorder generally associated with uncontrollable movements like tremors, rigidity as well as problems linked with maintaining body balance and coordination. Symptoms generally develop slowly and intensify over the period.

People may experience trouble in walking and talking with  the advancement of the disease. The patients may also exhibit mental as well as behavioral alterations, sleep trouble, depression, memory problems and lethargy.

This idea inspired Darwin to formulate the idea of "the survival of the fittest".

Charles Lyell and James Hutton:

Charles Lyell and James Hutton were famous geologists who greatly influenced Darwin with their theories about the beginning and evolution of the Earth. Charles Lyell proposed that the present state of the Earth was a result of small, gradual changes. James Hutton theorized that the processes that too place at the beginning of the Earth were still in progress.
