A hypothetical mutation in a squirrel population produces organisms with eight legs rather than four. These mutant squirrels survive, successfully invade new habitats, and eventually give rise to a new species. The initial event, giving rise to extra legs, is an example of 1. punctuated equilibrium 2. natural selection 3. allopatric speciation 4. changes in homeotic genes 5. neoteny 1 2 3 4 5 0% 0% 0% 0% 0% :30
