It has been a while since I last wrote. I actually did not initially have a question this time around, I just wanted to contribute something regarding a query someone posted a few weeks ago about Smilodon's saber teeth. I believe the person who posed the question was referring to this recent series of blogposts on the topic:
A 'traditionally realistic' hypothetical reconstruction: http://thesax66.deviantart.com/art/Smilodon-614353284
In addition to my own question, which I thought up as I was writing this, I suppose I'll just reiterate what the other person said: what are your thoughts on this?
My own question: when proposing a hypothesis like this to the scientific community, can simply do a review of existing literature and data, or does new data have to come up in a given report? For example, could you publish these blogposts as papers more or less as-is, or would the author have to actually handle the fossils himself and/or come up with something more than pust positing a hypothesis? And if such a hypothesis 'passes' scrunity through the peer review process, is it "officially" a theory in practice, at least until say, a Smilodon mummy is found?
