[QUOTE="OllieFranz, post: 62602095, member: 194533"] Yes, there is a limit to hybridization and the birth of chimeras. And that limit is a [I][B]result[/B][/I] of evolution, [U][B]not[/B][/U] a [I][B]barrier[/B][/I] to it. That is exactly why the question of ring species is an important part of the debate. Evolution is not about creating new species by combining two existing species. (It happens on occasion, when in plants sometimes the interspecies hybrids are viable -- but that is not evolution as we normally discuss it.) Evolution is about one species splitting into two. It is a slow, gradual process involving a physical barrier preventing two groups of the species from interbreeding until the biological changes will not allow fertile offspring when they are brought back together.
