Is This Science or Just Wishful Guessing?

   
    You’ll be excited to know that scientists have found three teeth, a pinky finger bone, and a bone fragment from either a leg or an arm in a cave in Siberia. 
    From this evidence they have deduced that this was a 13-year old girl, whose mother was a Neanderthal and whose father was a Denisovan. They have also deduced that the mother and father mated willingly, and created a thriving interspecies family, proving that there was peaceful coexistence between these two species. 
    These scientists were excited because this has been the first evidence of these two species coexisting. 
    Wow! And all from two bone fragments and a couple teeth. 
    My question is, in what other disciplines can participants get by with such leaps of conjecture and not be ridiculed into the outer reaches of society?
