Which term describes the rise of new species within a created kind?

The term that best describes the rise of new species within a created kind is "intra-baraminic." This concept is rooted in the idea of baraminology, which is the study of the boundaries of created kinds (baramins) based on biblical creationist views. Intra-baraminic speciation refers specifically to the diversification and emergence of new species that occur within these defined kinds, emphasizing that, while these new species share a common origin, they exhibit variations that can lead to separate species within the same baramin.

In contrast, the other terms refer to different types of speciation that are not limited to created kinds. For example, allopatric speciation occurs when populations are geographically isolated, leading to species divergence due to the separation. Sympatric speciation involves the emergence of new species from a single ancestral species while inhabiting the same geographic area, often due to factors like behavioral differences or niche specialization. Inter-baraminic would imply interactions or connections between different kinds, rather than within a single kind. Thus, "intra-baraminic" precisely captures the concept of speciation within a single created category.
