Ann, another reason is that canina has now thought to be the most recently emergent species. Study might help determine if so-called canina inheritance is unique or maybe a standard evolutionary strategy and way-station along the road of speciation. If canina-inheritance can be correlated to glaciations in Europe and insects that lived or evolved during those glaciations, we will have learned a lot about the evolution of at least this section of Rosa. | ||

The reason may be that R. canina has such an unusual "love life" with the seed contributing 28 chromosomes and the pollen only 7. As a result, populations are very matriarchally similar. Establishing differences between populations in different areas might tell something about how evolution happens. | ||

Henry or anyone else, Do you have any insight as to why the Europeans have so much interest in the genetics of R. canina sensu lato? I was surprised a decade ago to be told by several academics (North American variety) that if there wasn't research money, projects wouldn't be done. I can only assume that most research world wide has to be driven by research funding. So ....why canina? Likewise why not gallica, sempervirens, or even spinosissima? | ||
