Competition for resources. More recently extinct ones were hunted and out-competed by humans.

>>2435488
I can't see that honestly, surely humans alone wouldn't be able to just kill them all?

>>2435499
That's exactly what happened though. Megafauna breeds slowly and can't defend itself against humans.

Human migrations always led to megafaunal extinctions within a few generations of arrival.

The Old Ones liked their pets big.

Why is Africa the only one where the fauna survived?

>>2436666
We wuz

>>2435499
Homo sapiens is -literally- an extinction event. You must understand that ecosystems have sensitive equilibriums and there's a limited amount of organic material. As that biomass is redistributed over various emergent species, it puts stress on the ones that already exist.

I wish Guillermo Del Toro would make his adaptation of 'At the Mountains of Madness'.

Because there were greater levels of oxygen in the atmosphere I think

>>2436768
This is also a contributing factor, yes.

>>2436768
then why do elephants exist? checkmate atheists

>>2436666
Homo Sapiens has yet to arrive there.

>>2436768
>there were greater levels of oxygen in the atmosphere I think
nope.

>>2435481
This picture is so wrong. Emperor penguins are not tall enough that they come up to a human's chest.

>>2436887
the penguin height is fine, but the human is way taller than average. That's the average height of a man in the US. If we average in women and people from other countries the average adult human isn't much taller than an emperor penguin.

>>2436666
Animals in Africa would have evolved along with humans. They would have adapted to the hunting done by humans.

>>2436876
Technically Africans are the most genetically pure Homo Sapiens. Europeans have Neanderthal admixture and everyone else has a Denisovan admixture.

They provided less meat for people so didn't get hunted as much.

>>2436917
But neaderthals went extinct

>>2437064
Indeed, but rather than being completely exterminated they were subsumed by the much larger Homo Sapiens populations through interbreeding. Blonde/red hair, hirsute bodies, and a feature on the skull called the 'occipital bun' are inherited traits from Homo Neanderthalis ancestors.

Holy fuck, I never knew emperor penguins were that big. That's frightening.

>>2436892
Lol wtf he's 5'7" nice try you fucking manlet

>TFW no kaiju to put humanity in it's place

The world is kinda boring when humanity is the only dangerous species to itself

>>2438388
That's probably the average height for our species. The average IQ is 100, brainlets right?

>>2438388
He's 5'9" which is average for a male American.

Average for all adults around the world is closer to 5' even.

i have 115, but mein head is fugging big because i am a living fossil of neanderthal, i ve met some peoples who can reap a way higher iq while having a significantly smaller head than me

>>2436666
because homo sapiens is native to africa, and megafauna evolved next to him
On other continents, humans are invasive species

>>2438930
They've debunked that.

Pretty sure I remember reading there being more oxygen allowed insects to be bigger.
Maybe the oxygen helped them grow bigger and if oxygen made the average insect bigger then maybe mammals had to be relatively bigger to consume "small fry"

lol step it up jamal

>>2437079
Actually, no. The genes for red/blond/brown hair in homo sapiens is a completely different gene than what the neanderthals had. As well as different colored eyes.

Don't believe me? Look up that black actor in the Thor movies with the yellow eyes. That's his natural eye color.

>>2436882
a greater ratio, perhaps. but think about our ancestral lineage. we've only gotten bigger.

>>2436892
reminder that average is an impossible thing to find. the median statistic is what you're looking for.

>>2438938
The big insects thing was hundreds of millions of years ago, way before the megafauna mammals existed. The oxygen levels haven't changed that much since big mammals became a thing.

Big land animals have existed for hundreds of millions of years, save for a short break 65 million years ago and in the past 50000 years. It's probably just an ecological niche that will always be there, save for extinction events targeting them specificaly.

>>2436666
Evolved with humans, plus its much less developed. More space where animals can live without being shot because yuppies think they're scary.

>>2435499
They were super tasty, like the finest buttered streak or something.

>>2435499
Mammoths were killed off by humans but the end of the ice age resulted in the loss of most of their habitat

>>2436768
I think that's only for bugs being bigger.

>>2441000
It's not for anything being bigger. Dragonflies of similar size to Meganeura lived in the Permian despite significantly lower O2 levels than the Carboniferous.

>average US man is mantet

>>2436892
>the average adult human isn't much taller than an emperor penguin.
Average male height is 170cm (5'7") and average female height is 160cm (5'3").
That makes our average human about 5'5", compared to our average emperor of 3'7". lol

>That's the average height of a man in the US
No its not. A US man is at least 5'9".

>>2435481
>you will never fuck a giant peguin in the cloaca

>>2435481
Humans probably contributed a lot towards megafauna extinction

>>2435481

Are you serious?

Emperor penguins are fucking tiny. I used to think they were a lot bigger too, until I looked at pics of them around humans. They are absolutely not near the average adult human height.
