Dragons are usually shown in modern times with a body like a huge lizard, or a snake with two pairs of lizard-type legs, and able to emit fire from their mouths. The European dragon has bat-like wings growing from its back.A dragon-like creature with wings but only a single pair of legs is known as a wyvern.lthough the indigenous name for a dragon in Japanese is tatsu (ãã¤) , a few of the Japanese words for dragon stem from the Chinese word for dragon, namely, ryÅ« (ããã) or ryÅ (ããã) (traditional :é¾; simplified :ç«).
Each peppered moth in the samples was identified by phenotype as melanic (solid black), typical (patterned wings), or intermediate (insularia). The range of phenotypic differences results from multiple alleles at a single locus, with the allele producing full melanism as dominant (Lees and Creed 1977; West 1977).
The Peppered Moth - An Update (From Ken Miller's Evolution Page) For years the story of the peppered moth, Biston betularia, has provided one of the best-known examples of natural selection in action. The story of the moth was outlined on pages 297-298 of the Elephant Book, and highlights the experiments of British ecologist H. B. D. Kettlewell.
