Creationism and Baraminology Research News

This blog has been superceded, and is only here for archive purposes. For the latest articles, please see us at our new location!

An ongoing list of creationist research projects. This is not a creationism-verse-evolution site, but a site to publicize the research work done by members of the creationist community and the intelligent design community, or research work by the science community at large constructively relating to creation topics. Evolutionary critiques may be included on occasion but only under special consideration, and especially where the research pertains directly to developing a creationist model.

The Tsoan Monobaramin

In the latest Journal of Creation, Jean Lightner has pointed out a new monobaramin (a monobaramin is a set of taxa which belong to the same baramin) based primarily on breeding studies.

Lightner's basic points:

  • Ovis (sheep) interbreed readily with each other

  • Capra (goats) interbreed readily with each other

  • Capra and Ovis mate often when in the same location. While viable offspring is rare, there are confirmed cases.

From the chart, it seems that the main confirmed data linking Ovis to Capra was a viable hybrid of O. Canadensis with C. Hircus.

UPDATE -- apparently my eyes deceived me. I don't have it in front of me, but Jean let me know that I misread the chart and Capra and Ovis are linked by a hybrid of O. aries and C. hircus.

She also pointed out the significant homology between the sheep, goat, and cattle genomes. Goat and cattle are the most closely aligned, both having the same number of chromosomes (60) and similar layouts (both have 29 pairs of chromosomes with the centromere near one end). The sheep genome differs slightly, but can be easily explained by two robertsonian translocations, which Lightner points out seems to be nonrandom and has a driving mechanism.

I find the genetic data very interesting, but would caution the reader against assuming too much, considering that the genome may not even be the primary originator of form.

Lightner pointed to an interesting paper, Parental origin and the timing of de novo Robertsonian translocation formation.
