Is there any chance that dinosaurs will be on earth again? the typical kind of dinosaurs?

Question

through science, evoulution or anything else?

Answer 1

Birds are maniraptors, so around 9000 species are still with us.  A re-evolution of extinct dinos is as likely as the inmates of a cemetery being reborn.  A Jurassic-Park-like bit of genetic-based tinkering is presently only possible in books and films.  Assuming it could theoretically be done, you'd require good quality DNA from critters that died 65 million years ago or longer.  The chances of anything like that being preserved are impressively, seriously minute.

Answer 2

I think it's creepy how our avatars look alike, lol

Answer 3

Probably not, but one can never be too sure about it.  The fact remains that it will always be a possibility because they have a living relative still in existence, the birds.  this means that any point they can begin to take the evolutionary path towards becoming dinosaurs again.  This would have to be associated with changes in temperature and environment of the planet because when the dinosaurs were around conifers were dominant, CO2 levels were higher, and temperatures were as well.  Who knows maybe thats what we are looking at if we experience run away global warming lol.....

If they did become similar to dinosaurs they would be differnet in some ways.  They arent going to be exactly the same because i think it would be impossible for an organisms to re-evolve into the same species....most likely the dinosaurs would be better equipped for the new environment and new time.  If dinosaurs come back maybe osme of the organisms that we are living with now  would still be aorund so they would have to evolve in harmony with them so they dont out compete each other

Answer 4

depends on what course current life takes. if all life went extinct right now, who knows what would evolve the next round, maybe everything will be miniature, imagine that.

And if you look at current animals that are a live today, there's still some "dinosaurs" alive. Heck, birds are the closest relative. And look at some reptiles.

Answer 5

There's no such thing as a "typical" dinosaur.  Dinosaur species ran the gamut from those that live in the oceans, to land animals, to ones that could fly.

It would very difficult for them to "re-evolve", and be anything like what they were millions of years ago... firstly because everything about the earth, from the atmosphere to the overall climate has changed DRASTICALLY since the age of the dinosaurs.

Secondly, while natural "de-evolution" is possible, the nature of evolution tends to improve on a species rather than reverting it to an earlier form.

As for recreating them through science... well, don't count on it happening soon.  Jurassic Park was an awesome book, but it was fiction, with some pretty gaping flaws in the core science (not the least of which being that it would be very difficult for dinosaurs to survive in our oxygen-rich atmosphere... there was far less oxygen while they lived... walking around would be to them what climbing Mt. Everest without an oxygen tank is to humans).  That's not to say it could never happen, but I don't think we're quite at that level in genetic research just yet.

Answer 6

As we all know every thing is possible in this giant world!!

I think that this will happen as we all know the earth is getting warmer and warmer so the dinosaurs can live in tropical areas but if sientics can find a way to make the earth colder so I think it would be your tuff luck hahaha.
