ABSTRACTMetaphors are a genuinely human construction. They are used to improve communication and they are a very powerful tool that might have an influence in human evolution. In this article I argue that metaphors, transformed in powerful memes, adapt to a new communicative niche and contribute to transform it. In order to prove this hypothesis, I study 319 cartoons published in the wake of the Germanwings air crash, where I inventory 144 metaphors. The study shows the conceptual metaphor evolution for (...) a period of 2 weeks, and how the metaphors changed as a result of the variations in the communicative niche, becoming much more efficient communicatively.

In this article I study the genesis of metaphors from an evolutionary perspective. Analyzing 414 cartoons published after the death of the cartoonists of the French satirical magazine Charlie Hebdo, I propose a metaphoric founder effect with the metaphors “PENCIL IS A WEAPON,” “PENCIL IS A CARTOONIST,” and “PENCIL IS FREEDOM,” and a subsequent metaphor drift that creates many related metaphors. Additionally, the success of these metaphors turns the pencil meme into a very efficient and fast-spreading item representing not only (...) the work of cartoonists, but also the fundamental values of Western culture, such as freedom of expression.
