chimère

Chimäre is a term with roots in Greek mythology and modern biology. In classical myth, a Chimäre is a monstrous hybrid creature, commonly depicted with a lion's head, a goat's body, and a serpent's tail. The name derives from Ancient Greek khimaira, often interpreted as "she-goat" or as a fanciful, composite being. In ancient art and poetry, the Chimäre symbolized a terrifying combination of incompatible forces.

In biology, a chimera is an organism composed of cells that come from two or more genetically distinct zygotes. This can occur naturally when two embryos merge early in development, or artificially when tissues, cells, or organs from a donor are introduced into another individual, such as in transplantation or experimental chimeras. Chimerism is distinct from mosaicism, where many cell populations arise from a single embryo.

Chimera concepts are used in developmental biology and transplantation research, where chimeric animals and tissues help study organogenesis and immune interactions. In medicine and ethics discussions, the creation and use of chimeric organisms raise questions about animal welfare, cross-species interfaces, and regulatory oversight. In literature, art, and popular culture, the term is often used metaphorically to describe anything that blends incompatible parts or identities.

In German-language contexts, Chimäre denotes the mythic creature as well as the biological phenomenon of chimerism. The term appears in scientific writing, fiction, and media, reflecting its long-standing association with hybridity and the merging of diverse forms.
