Punctum Saliens

Things were pretty much perfect in the ol’ Garden of Eden before the whole “apple” incident, right? And God created everything and said (and I quote) “That’s frickin’ Good!” So, were there ticks and mosquitos and fleas and tapeworms and hookworms in the Garden? And if so, what was their relationship to humans and animals? Were mosquitoes “nice” blood suckers who didn’t inject poison into their victim to make an itchy, red welt? Did fleas bite but not cause disease and itching? Did Adam have tapeworms but they caused no ill side-effects?
