Charles Darwin’s claim, that the species level of classification is just as arbitrary as that of any other taxonomic level, is supported by all of the following observational failures except: the inability of a cloning species lacking biparental reproduction to interbreed with a different species the inability of an asexual eukaryotic species to interbreed with a different species the inability of a sexually-reproducing eukaryotic species to interbreed with a different species the inability of a prokaryotic species to interbreed with a different species the inability of an extinct species (like a dinosaur) to interbreed with a different species
