The distribution of this species is from British Columbia in Canada, through Washington, Oregon, California and into Baja California of Mexico. Presently, seven subspecies are recognized,
They are not even species and you call this macro-evolution? Please!
In fact, by analyzing electrophoritic separations of selected enzymes and studying DNA patterns, the two subspecies klauberi and eschscholtzi are different species by every definition. (Wake, Yanev and Brown, 1986) This poses a very interesting problem. Should the species Ensatina eschscholtzi be split into two or more species, or be considered a single species? If the species is to be split, where does one draw the line?Also posted earlier by VadeRetro in #819
But where would you draw the line? Why are they the same species if they can't interbreed? Or is there also another definition of species? Why can't the two populations that "close the ring" not interbreed?
So many questions...
