User blog comment:Kogath/Monster Hunter: World Discussion/@comment-27356783-20170621051130

After reading about MHW and researching all I can about these new monsters, I've devoloped two main theories:

This could be set during the discovery of the New World, and as such monsters such as Deviljho, Lagiacrus, or Gore Magala have yet to be discovered.

And second, this could be set in a world way after the events of MH4, Gen, etc. Some monsters have evolved to fit to in these new environments, such as Anjanath. Anjanath might have evolved from Deviljho. During evolution, Janath may have devoloped poor eyesight because it's smell became much more effective, hence the nostril fringes. The "wings" might be used to attract mates or used as a threat display. The reason for trading in the Dragon element for Fire is possibly because as Janath found itself with prey items without many elements or blight based attacks, the Dragon element eventually became useless. It's metabolism lowered as it found itself surrounded by an abundance of prey. It seemingly became calmer.... or, as I said before, gained poor eyesight, as in the livestream the hunter was standing right in front of Anjanath and it didn't even attack. Then again, Great Jagras was headed straight for the hunter and instead went for the Aptonoth. Maybe these monsters have yet to see a human before and have yet to register them as a threat? I dunno.

The raths may have been so succesful that evolution was uneeded, so they remained almost the same.

The Jagras? I dunno if they evolved from a different monster or just a lizard, but there's one point in the stream where the normal Gras are seen standing upright. Now, to my knowledge, the only other monsters that stand like that are Arzuros, Lagombi, and Volvidon. I doubt they are reptilian Fanged Beasts though. Sure, it has a similar name to the Jaggis (I can't be the only one that noticed this similarity), but they don't look like dromaeosaurs or bird whatsoever. Fanged Beast? Fanged Wyvern? New class? It's currently unknown, and that makes it all the more exciting!

Kestodon looks a whole bunch like a Jaggi, and, you guessed, it may have evolved from them. What I'm most excited to see if they have a leader (Kestodrome or somethin'). It would be cool, and I'm excited to see what these creatures are capable of.
