In baraminology hybrid data is used to determine which species are able to reproduce with each other and thus logically belong to the same created kind (baramin). Hybrid data from birds in the order Passeriformes was examined. It was found that there is a large sparrow-finch monobaramin that includes over 1,000 species. One questionable hybrid, if confirmed, would potentially double the size of this monobaramin to include birds such as swallows. Ravens and crows are in a separate taxonomic category within this order and have no hybrid data that would connect them to the sparrow-finch monobaramin. Given the variety within these monobaramins, it is evident that God cares for his creatures and has enabled them to not only multiply but also diversify while filling the earth.

One goal of baraminology is to identify extant species that belong to a common created kind (baramin). One important method of determining that two different species belong to the same baramin is the ability to form hybrids between them. As long as there is significant embryological development, hybridization is considered, by most creationists, to be conclusive evidence that creatures are from the same baramin.1 Taxa connected by hybrid data are said to be in the same monobaramin. One problem is that a lack of hybrid data does not, in itself, suggest that the two are necessarily from different baramins. This is because barriers can arise which make hybridization difficult or impossible even when creatures are known to be related.

Hybrid data is more complete for animals that are domesticated or held in captivity. Indeed, the rare hybrids between sheep and goats would likely never have been identified if these two domestic species were not commonly kept together.2  Several years ago a compilation of all known avian hybrids was published by Eugene McCarthy.3 Again, a very large proportion of the hybrid reports come from animals held in captivity….
