In the suggest period between 200,000 and 12,000 years ago, humans were living a nomadic lifestyle. The humans of this period were hunter-gatherers, and they were constantly moving from one place to another in accordance to the food supply and climate conditions. Because of this constant movement and constant search for better hunting grounds and places where there's much bigger and more constant supply of fruits, vegetables, root plants, they managed to disperse in very big space and little by little to colonize the planet. In this period the cultivation of plants was still not taking place, and also the humans still hadn't managed to domesticate any wild animals, apart from the wolf which gave rise to the dog, but it was used for hunting, not as a food source.

<h3>The types of variables.</h3>
In an experiment, there are two (2) main types of variables and these include the following:
<h3>What is an independent variable?</h3>
An independent variable can be defined as the variable that is being manipulated by an experimenter or researcher. This ultimately implies that, it is typically considered to be the cause in an experiment and it stands alone because it cannot be changed by any variable being observed or measured.
<h3>What is a dependent variable?</h3>
A dependent variable can be defined as the variable which signifies the effect of an independent variable and it is dependent on other factors because it's the part of an experiment that's being observed or measured.
Based on the information provided about this experiment, we can infer and logically deduce that the independent variable is psychotherapy while the dependent variable is the people.
