Think of it, how would various aspects of humanity be changed if we descended from primates rather than apes and get retain our tails?

What would change about humanity if we essentially had monkey tails?

Physiology, anatomy, culture, all of that and more!

I'm eager to hear what you guys think!

I was just thinking out of curiosity, just hear me out, please.

Let's just say that, somehow, a human managed to inject a live bee with his DNA. And that bee goes and procreate and etc.

What're the chances that a humanoid bug species could exist in, say, a few million years? One that can walk and talk in a similar fashion to us?

If you think they can, how?

If you think they couldn't, then why?

And how would you handle their evolution?

Okay, so just to get the "uhm actuallys" to shush, I mean Non Avian Dinosaurs. Ceratopsids, non avian theropods, maybe some tiny sauropods, etc. Not modern birds. Don't give me that cop out answer.

Now as much as I froth over prehistory, I'm better at alt history than spec evo so this is NOT my forte. But I'm working on an alt history crackpot timeline, and I wanna have some dinosaurs survive.

Only to the point that they still exist and are uncommon at best. But not to the point that they are widespread and dominant so that most modern mammals and humans still evolve similarly.

Now of course butterfly theory dictates that this would mean if humans evolve civilization does not arrive as we know it... but just pretend it does.

Where is the best spots for dinosaurs to survive? I've seen India thrown around a bunch plus the poles as potential spots for Cenozoic survivors.

I did this sometime ago in one day. I tried to come up with an aquatic mermaid descendant of Homo Sapiens, mostly drawing inspiration from otters and seals. Realistically, she probably would’ve worn light clothes or jewelry, assuming this species is as intelligent and social as us. Marked as NSFW to be extra safe.

Since tardigrades can survive in space, how would a lifeform that not only survive but thrive in outer space would look like ,behave and feed on?

Who Needs a Moon When You Have An Whole Planet

Something unique about Macroterra Is It's lack of a moon, It has something similar tho In the form of It's partner, Venoct.

Venoct and Macroterra are part of an double planet system, instead of having an moon orbiting them, the planets orbit around each other.

While Macroterra Is very earth like, Venoct Can be more compared to Jupiter and Saturn, an gas giant with an ring consisting of rocks.

Macroterra being an part of this system has great influence on It.

A few examples:

-Tides are more extreme and rainfall Is more frequent.

-Days are a lot longer, while an day on Earth lasts 24 hours an day on Macroterra would take 24 earthern days, with days getting very hot and nights very cold.

-Solar eclipses are a lot more common.

-Instead of an moon you would see Venoct glowing In the night sky, making nights very bright.

Life on Macroterra Is a lot different then that on earth but the life forms of Macroterra grew used to It pretty quickly.

This is most intelligent Creature in Einstein-A-25. They have Advanced technologies , Science,Culture and military. This creature is mixed gender ( He's born as male, And after teens he Start to turn female . After that When's this creature give to birth Baby. He turn Male again. So what do you think it's weird right?

Hopefully that's the right title format. I'm new to reddit.

The main thing

So, this is from Castanis, a world I'm creating, and it's one of the animals. So, sort of related to speculative evolution, though not pure spec evo (is this allowed?).

But, I've been creating a lot of images about this particular animal, the Collosal Seratorn, but I'm not too sure about them. Specifically this skeletal I'm making at the moment. I'm hoping someone/people on here will be able to provide some helpful criticism, on whether it's realistic or not.

I'm mainly worried about things like:

Is two spinal columns too far-fetched? to be honest I created that feature mostly for uniqueness, and it has little functional aspect apart from allowing the body to squish in some animals, and generally more strength. The organs do work around the columns, the anus is at the base of the neck, and spinal cord runs down through the bottom spine, being protected along the neck by sort of gastralia (like on the belly of a T. rex)

I also attached the jaws (horizontally hinging, like an insect's) via a ball joint, which I am beginning to regret as it is kind of... needless. If necessary I would definitely change it to a more 'normal' jaw joint.

Note: there is also a pair of pharyngeal jaws, like a Moray Eel's, that are visible.

Here is the thing with skin on, if you were curious:

*self explanatory*

Also if you have any general things to say, like

'this thing can't fly (please say why)'

that would be kind of crushing, but I would need to hear it.

or questions, etc... I will definitely answer them

Yeah, thanks if you read this.

For example, would a super computer that is powered by trillions of microbes be considered speculative evolution? Like the microbes didn't evolve initially to be in a computer but if they did evolve to be more efficient or something would that fit the criteria?

Basically what the title says.

Context

Last time, I created a scenario where a giant ravine the size and depth of the Mariana Trench suddenly appears in Siberia, 25 MYA.

Due to the sheer temperature of the water at the bottom of the ravine, I imagine large birds of prey may use it to boil their prey. By doing this, they may be able to get more energy out of their food, thus allowing them to grow larger brains.

Eventually, they may use this heightened intelligence to coordinate more complex pack behaviors, and work together to carry megafauna that would normally be too heavy to carry alone, like the Greater False Ox (A goat who evolved to be much larger and live in the Tropical Zone).

Question

The issue? They might not be able to create agriculture, a necessity for any civilization, due to their inability to eat plants.

…But they may be able to create agricultural society through livestock, such as large goats and other local herbivorous megafauna. I’m not too sure if any historical civilization could sustain itself purely off of meat though.

Extra Lore

Due to a combination between their isolation and relative lack of dexterity, they may be stuck in the Neolithic Age for millennia, not having the physical traits necessary to smelt iron.

However, this may come to an end in the Mongol Invasions of the 1200s. The steam from the bottom of the ravine will heat up the surrounding tundra into dry grassland, perfect for the Mongol cavalry. Even then, they wouldn’t be able to traverse the rocky terrain of the Ravine. The message will be sent loud and clear however. Their first ever contact with humans was highly aggressive.

Just like the Japanese, these Ravinians may have a period of xenophobic isolation from the rest of the world y may also take some Mongols as slaves. Given they are a different species, they may breed them like livestock and use them as a source of food. They will also quickly technologically advance to the Iron Age, or even use primitive gunpowder weapons.

Starting in the 1600s, they might have a conflict with the Russian Empire. At first, they might struggle to get down the trench. However, on their holy mission, they might be able to reach and capture the Cryogenian Zone. After that however, the Ravinians may use guerrilla warfare to take back their land, albeit with great causality. This is a war that may span decades if not centuries. During that time, they may either go around the trench to continue east, OR just stop there.

During this time, the Ravinians might quickly industrialize. Due to their isolation from the rest of the world, they will focus on building their own technology, advancing both gunpowder and steam technology. A minority of them could be introduced to Christianity, and be converted to actually respect humans as people with equal rights as them.

NEXT TIME: CHAPTER 3: THE MODERN ERA

This Creature is Strongest , Fastest , Smartest and Successful predator in Einstein-A-25.he has four foot and Two arm with Spike for Hunt the prey. also he has orange skin Camuflage for hiding from prey while hunting. He verticaly open own mouth (how weird right?) , big cute eye ,and Circle hole for hearing and discernment air direction. Adamius is most caring parent in Enstein-A-25 (they give birth alive for one baby Adamius).

Near rock shelf's and cliffs in the Briar forests you'll see mud and stonework tubes cemented to the rocks. Your initial thought might be that a Tatmot built these intricate towers but infact it's the brood chamber of a spearfly. These highly aggressive and territorial solitary predatory arthropods.

Despite the convergent evolution between them and wasps they actually have more in common with shrimp. They still need a wet or highly humid environment to raise their brood of eggs the towers collect and trap rainwater. The larva free float in the liquid for about 4 weeks while the mother collects prey for them. The adult then grinds the meat into a paste then disperses it into the water.

Spearflies don't possess venom instead they just repeatedly stab their prey with their 20 cm serrated stinger or their pincers. They're lightning quick too meaning it's incredibly difficult to hit them back. Most of their prey is colorblind (including Tatmot) so their vibrant colors act as a type of dazzle camouflage, breaking up their silhouette against their environment. Spearflies have excellent color vision and are highly sensitive to ultraviolet and infrared spectrums.
