  • Speciation. What are species anyway, and how do new ones evolve? Here, you can explore different ways to define a species and learn about the various processes through which speciation can occur. This section also addresses the topics of cospeciation. — “Speciation”,

Applied Speciation will be presenting two papers at the National. — “Applied Speciation and Consulting, LLC”,
  • Speciation is the natural process by which new species are formed. The identification of speciation is problematic since it is reliant upon the determination of reproducibility in nature. — “Speciation - CreationWiki, the encyclopedia of creation science”,
  • We will focus on allopatric and sympatric speciation, but will also introduce two other modes: parapatric and peripatric. Gene flow, the loss or gain of alleles in a population due to the migration of fertile individuals or between gamete populations, is reduced in all of these speciation modes. — “Evolutionary Biology/Speciation - Wikibooks, collection of”,

  • Speciation is the evolutionary process by which new biological species arise. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are geographically isolated from one another: allopatric, peripatric, parapatric, and sympatric. — “Speciation - Wikipedia”,

  • Speciation is a hypothetical process by which new species arise. Evolutionists, typically atheists, insist that speciation should occur when gene-flow stops between two sub-populations due to geographic or behavioral isolation. — “Speciation - Conservapedia”,
