Will Homo Sapiens still thrive if Dinosaurs were still alive? 

Cool Godzilla

Is it true that Homo Sapiens have 10 million in population?

SasquaDash

Early Homo sapiens would probably have a hard time dealing with dinosaurs, however, it's likely that they would figure out a way to survive around them (and possibly even hunt them), like they did with the megafauna that actually coexisted with them at the time.

HinikunaGoji

Depends. We shouldnt be conpeting with each other's niches at all so I think direct conflict would be a huge problem.

What could be a porblem is if they upend the ecosystem. This could have devastating affects on biodiversity.

Also they could frequently target our livestock.

So i think they would have a harmful effect but in a subtle way.

Xenotaris

Homo sapiens would not even evolved since dinosaurs would already occupied those niches had they never went extinct. More than likely Troodontids would have taken the evolutionary spot in place of primates

HinikunaGoji

Xenotaris

well if the idea is if dinos miraculously materialized now, no dinosaur shares the niche that humans currently do

Xenotaris

In that case, if were talking about modern humans then. I believe the dinosaurs will behave like any other animal. They'll probably gain a fear of humans after a while.

HinikunaGoji

It wasnt specified, so idk which one it is

Cool Godzilla

Xenotaris I don't think Homo Sapiens will stop evolving, no matter what happens, it is not possible that humans will stop evolving.

Cool Godzilla

SasquaDash, Agreed.

Cool Godzilla

HinikunaGoji I think if Dinosaurs still survived, I think it will damage not only the early humans but the animals and change the outcome in the future.

Cool Godzilla

Maybe they could use the strategy that scared predators in early human times, fire. Maybe though, some dinosaurs maybe were fearless.

HinikunaGoji

Cool Godzilla

what xeno meant was that if the dinosaurs had survived, humans would not have even evolved in the first place

Xenotaris

Cool Godzilla

Yeah I meant had the asteroid not ended the non-avian dinosaurs 66 Million Years Ago. I highly doubt that primates would have had the same evolutionary path as they did in our reality. Especially if dinosaur families like the dromaeosaurids had already dominated the arboreal food chain. 

I highly doubt larger and advanced primates would had evolved. It more stand to reason that sapience would evolve from the dinosaurian stock given they would be the dominate lifeforms in a similar manner that humans evolved from the mammal stock of our reality.

HinikunaGoji

Plus mammals were forced into limited niches and werent able to diversify until the extinction

Xenotaris

HinikunaGoji

yep that too

Cool Godzilla

Xenotaris HinikunaGoji Although I don't know what those words mean, I think I get it. I forgot about what happens if the asteroid didn't ever hit the earth, that would have changed a lot.  

Cool Godzilla

Xenotaris You really know a lot about outcomes and theories, thanks for making it clear. HinikunaGoji Good point. 

Cool Godzilla

I need some time to think about what happened when the Asteroid didn't hit the earth.

Xenotaris

Yeah I self-studied evolution, particularly dinosaur (life long dinosaur-nerd) and human evolution (for social studies project)

Cool Godzilla

Xenotaris Hey Xenotaris, I think I fully understand what you meant now.

Xenotaris

Also recent studies of theropods suggest they were more intelligent than previously thought. 

Taking Tyrannosaurus for an example, its now believed the T. rex was as smart as a baboon.

So if Tyrannosaurus was as smart as a baboon, then that would mean the dromaeosaurids/Raptors, were roughly as smart as apes.

Troodons, Raptor relatives could potentially been as smart as early humans.

Cool Godzilla

Xenotaris Oh, Imagine Troodons and Raptors made houses and stone tools. XD

Hydra

hmmmmmm 

Xenotaris

Cool Godzilla

Yeah, that would be cool

Hydra

wait..

Hydra

would that mean the velociraptors would BE ABLE TO OPEN DOORS!!!!!!

Xenotaris

Hydra
Its a possibility, however anatomically its impossible for any theropod to turn its wrists facing downward. That also means, quadrupedal theropods are also an impossibility for the same reason.

So although a raptor could open doors, just not with its hands. 

Cool Godzilla

Xenotaris Maybe it's jaws

Xenotaris

Cool Godzilla

I think a combination of it using its jaws and one of its feet, similar in fashion in how some species of birds manipulate objects
