Displacement activities occur when an animal or human experiences high motivation for two or more conflicting behaviours: the resulting displacement activity is usually unrelated to the competing motivations. Birds, for example, may peck at grass when uncertain whether to attack or flee from an opponent; similarly, a human may scratch their ...
Brown and Wilson used the term character displacement to refer to instances of both reproductive character displacement, or reinforcement of reproductive barriers, and ecological character displacement driven by competition. [1] As the term character displacement is commonly used, it generally refers to morphological differences due to competition.
The degree of displacement in this example remains limited when compared to human language. A bee can only communicate the location of the most recent food source it has visited. It cannot communicate an idea about a food source at a specific point in the past, nor can it speculate about food sources in the future. [2]
Examples include predation and competition pressures, parasites, deceptive pollination, and mimicry. [20] Because these and other factors can result in reproductive character displacement, Conrad J. Hoskin and Megan Higgie give five criteria for reinforcement to be distinguished between ecological and ethological influences:
Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e., estimated age).

A forensic anthropologist can assist in the identification of deceased individuals whose remains are decomposed, burned ...
