what would of happened if the meteor that hit like a long time ago, hadn't collided with earth.?

Question

I mean will there still be dinosaurs? Thxs to those who answer

did humans evoilve from an animal. lol i didnt know and werent there cavemen when the dinosaurs existed i dont really know about this stuff thats why i asked it lol

Answer 1

Well...

They say... the further an event is in the past the greater it's signifigance in the future.
Before the extinction there were many more animals that were fiercer, stronger, intelligent, and better protected.

It is theorised that these jurassic creatures were mostly reptilian in nature. Their young left to fend for themselves at very early ages.

The impact gave rise to mammals that nurture their young and sustain social behaviours.

I think if dinosaurs had made it through the impact and ice ages. Many potential ancestors for humans would have been eaten. Also, I believe that the dominating intelligence would be much more barbaric. The events in our history we call atrocities could likely be a way of life for such a culture.

In my opinion, the impact was like an evolutionary catalyst for higher forms of intelligence.

since the cambrian explosion 540 million years ago which resulted in shelled organisms. There has only been one catastrophic asteroid to cause wide spread extinction.

it's amazing to think that such an asteroid hit in this scale to provide an evolutionary jolt for mamals.

so.. If you shrink the sun to the size of a ping pong ball.. the earth becomes a mote of dust 2.5 meters away.

It almost seems improbable for such an event to happen by accident.

Answer 2

Good question. The dinosaurs were a very diverse and successful order of animals. No one knows for sure if they'd continue to flourish. Given all the changes the earth has gone through since, I'd say that, yes, they'd continue to exist, but probably would have adapted into different sub-species and forms from 65 million years ago. The adaptation factors would be the four ice ages in the past. And less oxygen in the air now than then, which would probably diminish the size of the largest herbivores. (23% oxygen then to 17% now, as per samples found in a gem stone that began as tree sap.) Changes in rain dispersion, and the changes in plant life. Most all scientists studying dinosaurs agree that bird are descendants of raptors though. So you could say that distant members of the dinosaurs are still here.

Answer 3

There would probably still be dinosaurs. And Human race could not have been made because the dinosaurs would have eaten the animals that were suppose to evolve to humans. So i guess that the meteor that hit the Earth was a good thing.

Answer 4

it seems that mammals wouldn't have been able to get a hold because there was no environmental niche for them. When the dinosaurs died and the mammals survived they were able to fill the niches that were now open and evolve in thier own course. While the dinosaurs were alive they were killing the mammals and not letting them diversify, so when the dinosaurs died the mammals took over. These same mammals eventually evolved into primates and then humans so if that metorite missed earth it is very possible that the dinosaurs would still be alive (they lived for 150 million years, why not another 65?). It is certain though that humans wouldnt be here

Answer 5

Who can be sure? If that hadn't killed the dinosaurs off, something else might have eventually. But who knows what the world would be like today if that was the case? It's a question that can't be answered without a time machine and a way to divert a meteor.

Answer 6

An alternate theory states that the dinosaurs could have been wiped out by significant changes in the food chain, caused by a nearby gamma-ray-burst.
which could have eventually killed a good portion of smaller animals, and causing severe effects to the atmosphere.

possibly dinosaurs vanished on any change of circumstances, cause they reached a state where they were highly depending on their environment.

if they would have survived into the 19th century they would have died cause someone invented firearms

Answer 7

The dinosaurs would probably still here they were th dominant life form here for 150 million years until the extinction. They may even have evolved into a civilisation.

Answer 8

Awesome question.
No one really knows for sure but I'm guessing they would've been long gone by now. Some might still be around but there were other catastrophes that happened, like would they have been able to survive the Ice Age? They were reptiles so it would've been very difficult to.

Answer 9

An intelligent species of dinosaur would have made the asteroid irrelevant by nuking the planet.

Answer 10

If dinosaurs had not been killed they would have died anyway
after depleting earth of food, they were huge and needed a lot of food.
