Peripatric speciation is a mode of speciation in which a new species is formed from an isolated peripheral population. Eine Modifikation ist eine durch Umweltfaktoren hervorgerufene Veränderung des Phänotyps, dem Erscheinungsbild eines Lebewesens. mollusque commented on the word parapatric speciation. Modern principles of other fields, such as chemistry, medicine, and physics, for example, are integrated with those of biology in areas such as biochemistry, biomedicine, and biophysics. It occurs when populations are separated not by a geographical barrier, such as a body of water, but by an extreme change in habitat. Was ist Biodiversität? Occurring among populations having such a distribution: parapatric speciation.
