Up until 8,000 years ago there were many different types of elephants, with different tusk and trunk shapes. Most common of these living alongside modern elephants for many years were the four tusked elephants. Why did these elephants evolve? What did they use their tusks for? And why did they die out just leaving the two tusked elephants.

[@dynamo8846]

Another advantage of only having two tusks is that its cheaper to grow. What I mean is that maybe 4 tusked eleohants did not face any major extinction events (if someone wanna look that up that would be cool) so they just kinda evolved. Then when an extinction event like the end of ice ages happened having 4 tusks was simply too expensive energy wise to grow and maintain for such a large animal

[@TremereTT]

The elephant is one of these species who does terraform their living space, just like humans. Where elephants live forrests are turned into savanahs. Tusks aid the elephant to harvest from trees. So it's probably ok for them to loose their tusks. Yet they also need these tusks to dig for water in the pretty dry savanahs that they keep from becoming forrests . So this might make them more weather dependent in a time where weather becomes less stable.

[@scorpiusrexman1017]

@@Raison_d-etre scientists believed that a mixture of climate change and overhunting played a role in the mammoths extinction so even if we humans hunted them to near-extinction they were still doomed due to the changes in the climate that’s the reason why elephants are still around because Africa and Asia’s climate didn’t change as much since the last ice age That’s how they survived while the mammoths and mastodons didn’t mammoths and mastodons lived in a temperate climate meaning that any climate change occurred their food sources would die out and forests would expand thus mammoths and mastodons couldn’t adapt to the climate changing or the arrival of humans killing them for food while African and Asian elephants lived in tropical climate so their food sources and habitats weren’t affected as much by climate so they wouldn’t be drastically effected by humans hunting them because they’d still have a climate suitable enough for them to continue on thriving That’s the reason why elephants are still alive while mammoths and mastodons are extinct

There are a couple reasons as to why lower tusks were lost. 1.) Overall, the climate became cooler starting from the middle-late Miocene. The highest amount of heat transfer in an elephant occurs at the head, particularly the ears, trunk, and tusk tips. Having four tusks means more surface area for heat loss, which is disadvantageous when the climate gets colder. As such, losing the lower tusks decreases the amount of surface area for heat loss, allowing proboscideans to retain more heat. 2.) True elephants (elephantids) lost their lower tusks because they became increasingly more specialized to masticate their food a certain way. They went from a gomphothere-like grinding and shearing rotary motion to a front-and-back power shearing motion with their lower jaws. A number of different cranial and dental features needed to evolve so elephants could perform this action more efficiently, among them shortening the skull and mandibular symphysis, and getting rid of the lower tusks. All of this appears to be a result of the changing climate during the late Miocene that called for greater specialization towards grazing.

If chin tusks disappeared during the most recent ice age, the reason might be very simple. Upper jaw tusks could be used with closed mouths. Lower jaw tusks likely required opening the mouth for most strenuous tasks like digging or scraping. Opening mouths more than necessary in very cold climates would be a significant caloric drain, even if not deadly. Fewer calories leads to smaller size and less mass to engage in battles for dominance in breeding season.

@@joela6895 it's never from nothing, evolution tweaks and repurposed what is, and very rarely combines a number of smaller structures to create larger structures. Legs don't come from nowhere, they are repurposed from earlier uses, same with basically everything else. Evolution is supremely lazy, it will never create complex structures completely ex nihilo and will only change small things at a time.

I just want to hear this guy say "gumphotheres" forever

[@ZetaFuzzMachine]

Wow! That last bit hit me!

[@CHLOCHLOLP]

the idea of humans hunting these creatures that lived 10 million years ago just fucks with my sense of time so much.

[@craigdurso3005]

Imagine now how a group of half naked men about 3/4 our size , would then hunt down and kill several of these things ata a time 🧐

[@curious5887]

It’s just a mistake, many of these animal that died ten million years ago is because competition from other animal and also changing climate

[@GarryDKing]

tbh 4 tusked elephants look kinda wierd. I feel like elephants, like us, have evolutionary fashion trends. at one point it was trendy to have 4, but then the 2 tusks came in and proved to be better suited for life [and more appealing] so they went to having just 2. But because poachers target tusked elephants, they're now opting to just go tuskless.

[@TheSynecdoche]

Opting isn't the appropriate word here. Being born tuskless looks like a gene fault which happens to do the elephant's survival chances a favour.

Another great video, maybe you should do one that focuses on the first evolutionary wave of Proboscians: the Deinotheres

Thank you and yes I think that would make a good video

I’m always fascinated at how evolution seemed to throw everything to the wall to see what stuck and came out at the other end of different extinction events.

[@pocketmarcy6990]

That mostly occurred due to just how many niches were left open following the extinction of the dinosaurs

They were OP, and had to be nerfed.

[@SpinexF7]

4 tusks would be too op for damage and don't forget confusion and fear debuffs towards non elephants

[@johngorno4552]

What happened to the Four Tusked Elephant that we were promised in the thumbnail?!

[@curious5887]

He disclude Stegotetrabelodon, the elephant in the thumbnail, due to limited info on that genus

I believe our rendition of the elephant's ancestors are too hideous, I mean give them some more lip muscle..., they look so gross and weird...

[@I_leave_mean_comments]

You completely ignore sexual selection. It's likely sexual selection caused the differences... since we know that animals who live in groups and are fairly protected from predators tend to develop more extreme secondary sexual traits (mandrill, Irish Elk, peacock, etc).

[@markuskuhn9006]

Probably both since genes can't be passed on if the animal they are from dies

I suspect that shovel-tuskers used their shovel-tusks to dig for water in dry river beds in droughts.

They were wiped out during the battle of Gondor.
