So, you do not know what semimeoisis is, I presume. Semimeoisis happens sometimes in the formation of gametes. The segregation of the chomosomes is then in such a way that novel genomes (karyotypes) form instantly and the next generation inherits a novel karyotype and sometimes a completely novel phenotype. It is saltantional evolution (read Dr Davisons manifesto…he was no YEC but an OEC by the way). Due to such saltational mechanism (chromotripsis is the left over of the saltational process and can be observed when the control over it disappears, e.g. in some cancer cellls), we can simply not determine the border of the created kinds from fossil remains. We can only determine this border using the genetic information content of the whole genome (the baranome), as I published 10 years ago.
