Why is this trait particular to spiders? Is it an unforeseen and unwelcome result of breeding for the morph?
I realize that some people see snakes as pets, and some as profit. I'm sure some see them as both things. But is it ever ethically justifiable to allow a species sub-type to develop neurologic deficiencies that are a direct result of breeding for profit (or vanity?)
I'm not making a moral judgment here. But if the mutations caused by selective breeding for morphological variants are causing functional disorders, shouldn't we be asking ourselves whether we are justified in continuing to perpetuate any variant that begins to develop those disorders?
Or are they, after all, just reptiles?
