Skillicorn studied deception detection in text, like political speeches, where he says the process "becomes a whole lot easier." In written statements, four patterns emerge when someone is being deceitful: Skillicorn used those patterns to analyze U. presidential candidate speeches during the 2012 election.But he says it's much harder to recognize those patterns in a conversation.allometry: The relation between the size of an organism and the size of any of its parts.For example, an allometric relation exists between brain size and body size, such that (in this case) animals with bigger bodies tend to have bigger brains.Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low. adaptive logic: A behavior has adaptive logic if it tends to increase the number of offspring that an individual contributes to the next and following generations.If such a behavior is even partly genetically determined, it will tend to become widespread in the population.These all develop through an embryo that is enclosed within a membrane called an amnion.The amnion surrounds the embryo with a watery substance, and is probably an adaptation for breeding on land.
