In his talk on bird names Ken asked the question, “What is a species?” I answered that the answer is evolving. On my latest podcast episode I talk with Dr. Geoffrey Hill, a professor at Auburn University, who proposes that the compatability of the DNA in the mitochondria, 100% from the female, and the DNA in the nucleus, equally from the male and female (sort of but not really as in birds a lot of the DNA that codes for proteins used in the mitochondrial functioning and structure are coded for on the male sex chromosome, males are ZZ and females Zy). I write about this on a BirdBaner.com blog post and we talk about it on the podcast episode. If you’re interested in speciation I think you’ll find it pretty cool stuff.
Link to my blog post summarizing my understanding of this theory.
