[[WMG:The Eloi [[MetamorphosisMonster metamorphose into Morlocks]].]]
Your [[Film/{{Gremlins}} MOGWAI]] is [[Franchise/{{Pokemon}} evolving]]... [[http://www.cracked.com/blog/4-beloved-fictional-characters-who-slaughter-their-own-kind_p2/ MOGWAI becomes GREMLIN]]! Your [[Literature/KnownSpace PAK BREEDER]] is [[HollywoodEvolution evolving too]]... BREEDER becomes PROTECTOR!

Could the reason that there are no elderly Eloi be that those Eloi who are not eaten become Morlocks, no longer able to gain sustenance except through [[ChildEater eating their young]] who retain the ability to process plant matter? It'd prefigure the Babyeaters from ''Literature/ThreeWorldsCollide''.
* Someone on another forum pointed out a few problems with this interpretation. First, there'd have to be some change to the [[http://www.cracked.com/blog/4-ways-nature-brainwashes-you-into-taking-care-babies_p2/ baby schema]] in the Morlock brain to recognize young Eloi the way we recognize lambs, not the way we recognize human children. Nor does the text clearly establish that Morlocks know enough science to reestablish an Eloi ranch lost to natural disaster or overharvesting. And if the Time Traveller defeats them so easily using a blunt object and the light of a forest fire, they might not have the physical fitness to find another ranch.

[[WMG: When the Time Traveller (book version) mentioned that his earlier class struggle theory about the Eloi and the Morlocks was incorrect...]]
* …He was right. The creation of these two species followed an apocalyptic disaster turning the earth’s biome upside down. Plants were either unaffected or recovered but the animal populations never did. The surviving humans subsisted off of stored food until it ran out. When it inevitably did, they were faced with two choices: (a) adopt a protein-poor vegan diet or (b) engage in cannibalism. Those that took option A gradually evolved into the Eloi; their protein-starved bodies causing them to lose stature, their brains to shrink and they became herbivorous. Those that took option B gradually evolved into the Morlocks; as they became more and more carnivorous, their bodies adapted so that they were better hunters.

[[WMG: The Time Traveller wasn't human.]]
He's actually a visitor from an advanced world, and came to Earth with one of two objectives. He either A) actually had a time machine and wanted to see if humanity was responsible enough to be trusted with it yet or B) knew what would happen to the future Earth and came to warn them. Knowing that simply dropping into the world and telling them would get him institutionalised by a society that wasn't very nice to it's mentally ill, he set up a backstory of sorts as a respectable member of society and tried to warn them once he thought he might actually be listened to.
