CONTROL ANIMAL Meaning and
Definition
-
A control animal, also known as a control group or control subject, refers to a specific type of animal used in scientific experiments or studies for comparative purposes, typically in fields like medicine, biology, or psychology. It is a designated group or individual within an experiment that does not receive the experimental treatment or intervention being tested. Instead, the control animal is subject to the same conditions, manipulations, and environment as the experimental group, with the key distinction being the absence of the variable under investigation.
The main purpose of including control animals in research is to establish a baseline or reference point for evaluating the effects of the experimental treatment or intervention. By isolating the potential impact of the variable being tested, the control animal provides a standard against which the results from the experimental group can be compared, enabling researchers to assess whether any observed changes are indeed due to the experimental treatment or simply coincidental.
Control animals are typically chosen based on similarities with the experimental group in terms of species, age, gender, genetics, and other relevant factors, ensuring that any observed differences are directly attributed to the variable being studied. Careful design and implementation of control groups are essential to achieving accurate and reliable results, enhancing the rigor and validity of scientific investigations.

Etymology of CONTROL ANIMAL
The term "control animal" does not have a specific etymology of its own, as it is a combination of two separate words - "control" and "animal".
The word "control" originates from the Middle English word "countrollen", which was derived from the Old French word "contrerouler". This Old French term is a combination of "contre", meaning "against", and "rouler", meaning "to roll". Originally, "control" referred to checking or verifying accounts by comparing them to a roll or list.
Meanwhile, the word "animal" comes from the Latin word "anima", meaning "breath" or "soul". In Latin, "animal" referred to any living creature that could move on its own, distinguishing it from plants and inanimate objects.
When combined, the term "control animal" does not have a singular or distinct origin story.
