a potential Genus reclassification?

Pilirin Sep 28, 2007 09:47 PM

Emdoidea blandingi (underlined) the Blanding's turtle and Glyptemys ( Clemmys) insculpta (underlined), the North American wood turtle. These two species have repeatly breed and produced hybrids - with interesting combined features. Harding and Davis (1999) wrote a paper on these hybrids and Harding has taken photos (2003) of many hybrid individuals with interesting traits form both Genus species. The standard criteria for a viable species is the inability to breed and produce a viable offspring capable of reproduction. If two different species produce living young, the best to expect is a sterile 'mule'. Thus, if E. blandingii and G. insculpta are producing hardy hybrids ( As far as known no reproduction of the hybrids is known - and if so, would totally throw scientific turtle classification on it's ear!) Then, at best, according to the Linnanean scientific classification standard, the two above species of turtle should be then reclassified as separate species within the same genus (probably Glyptemys - thus, the blanding's turtle may become Glyptemys blandingii {underlined}). Especially, since Emdoidea is a monotypic Genus anyways.

yeah, I've wondered about that one myself. In regard to species classification though, it seems like herps and fish are complicated. Trout and Salmon as well as Kingsnakes, Milksnakes, Ratsnakes, Pinesnakes, etc are capbable of producing fertile offspring from cross-genera hybridizations. Most egg-laying colubrid snakes in NA can hybridize with fertile offspring. It's really crazy and I don't pretend to understand it for a minute. While I don't know much about the genetics behind the snakes, trout and salmon in separate genera with different numbers of chromosomes can produce fertile hybrids as well. That's just not right...
