Answer:
Everything changed during the Industrial Revolution, which began around 1750. People found an extra source of energy with an incredible capacity for work. That source was fossil fuels — coal, oil, and natural gas, though coal led the way — formed underground from the remains of plants and animals from much earlier geologic times.

Archaeology is a subfield of anthropology, which is the study of human culture. It offers a unique perspective on human history and culture that has contributed to our understanding of the ancient and recent past. It is the only field of study that covers all times periods and all geographic regions inhabited by humans; unlike history, which relies primarily upon written records and documents to interpret great lives and events.
<em>Prehistoric archaeology</em> focuses on past cultures that did not have written language and therefore relies primarily on excavation or data recovery to reveal cultural evidence. An archaeological site is any place where physical remains of past human activities exist. Even the smallest archaeological site may contain a wealth of important information.
Opinion or bias can cause the outcome of an experiment to be incorrect because it’s based off of a personal preference. That being said, any desirable outcome can be produced. One example of this would be human reproduction. Let’s say a person of Cuban race wants a mixed child. They would decide not to marry a Cuban spouse because it’s biased that the offspring will be only one race. Therefore, they would marry a person of a different race to provide a desirable outcome, which in this case, would be a biracial child. Bias leans a result toward one side, preferably the result desired. That’s how opinions and biases can cause the outcome of experiments to be incorrect.
