Talk:Peripatric speciation

From Wikipedia, the free encyclopedia

This article is part of WikiProject Evolutionary biology, an attempt at building a useful set of articles on evolutionary biology and its associated subfields such as population genetics, quantitative genetics, molecular evolution, phylogenetics, evolutionary developmental biology. It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy. If you would like to participate, there are some suggestions on this page (see also Wikipedia:Contributing FAQ for more information) or visit WikiProject Evolutionary biology.

Why is it peripatric speciation, but parapatry? I understand that eri and ara might be pronounced the same in American English (as in merry and marry being homophones), so is one just a spelling mistake for the other? or are the distinct for a reason? Felix the Cassowary 08:42, 20 Feb 2005 (UTC)

Peripatric speciation and Parapatric speciation, despite the similar names, actually refer to quite distinct processes. Parapatric speciation = speciation that occurs when there is some gene flow between the two speciating populations (neither complete isolation (allopatry) nor complete overlap (sympatry). Peripatric speciation is a subset of allopatric speciation where the two speciating populations have very different sizes, but are still completely isolated. Peripatric speciation is usually used to refer to the situation where isolated, peripheral populations rapidly speciate, and is thus often linked with ideas about punctuated equilibrium. If someone could revert the Peripatric and Parapatric pages to their pre-merge status, I'll happily flesh them both out a bit. --Tsackton 17:08, 27 Feb 2005 (UTC)

I'm new here...just figured out how to revert pages. I reverted this page and the parapatric redirect page to their old versions (pre-merge), and fleshed out the definitions a bit. --Tsackton 15:59, 28 Feb 2005 (UTC)
