biologically possible?

would it be biologically be possible to make a dragon?

probably bin here at least once or more or on another board...

say if we would have the technoligy to go on and screw with DNA and biological engeneering, would it be possible?

Yes, it would.

I wouldn't advice you to start any bioengineering projects with such lacking specifications. If by 'dragon' you mean several-tonnes reptile that flies on skimpy little leathery wings and breathes fire, then obviously no, that won't fly.

Of course they could fly, all you'd need is a little magic.

How would the dragon start the fire?  I could envision some kind of sac filled with hydrocarbons.

>>5 or matches

Such a large creature would probably take years to grow, and probably requires a specialized circulatory system to nourish its whole body.  In particular, the reptilian 3 chambered heart would lead to circulatory system phailure and death.  If it were the size of a whale, then a mammalian heart would suffice, else, it needs something better.

Flying is quite a stretch, given that even emus, penguins, and ostriches can't fly.

If by 'dragon' the OP means a several-tonnes reptile that possesses skimpy little leathery wings and curls up and dies, sure.

Talk to RedCream.

Terry Pratchett covers this briefly in his very scientific text "Guards! Guards!" (Corgi, 1989).

You could make something like a dragon. You could selectively breed lizards to be larger, then expose them to natural selection, then repeat. Perhaps artificially make genetic leaps that would take millions of years to occur by chance, like givin them 20 extra vertebrae by using snake genes or something. You then selectively breed 10000s of these lizards till they adapt to the new changes and can survive in the wild, possibly with an advantage.

They would need a food source capable of sustaining them. Larger lizards can survive in colder conditions so it would be fine for them in the African Savannah compared to their smaller counterparts who need to lay in the sun before doing anything. With a combination of genetic modification, mad selective breeding followed by artificially aided natural selection you could create a grazing lizard which grows to a large size and can exist in a natural habitat.

OP here, i lacked specifications indeed. say;
is it possible to biologically breathe or spit fire, by say, some chemicals in the stomach or in the spit that if they mix with air or with each other they catch fire?

reptillian ofcourse...not immedietly ridiculusly big, at least a possible sise to maintain life.

no use of other animals, create a new one, design and create.
maybe like that pterodactyl from long ago it could have a leathery skin? wings big enough to hold him up?

also>>9
that whas what i was thinking about when i started this thread :)

thank you for the nice words :3

I think it is techinically possible to make anything, however as for practicality, I would go with >>7.
We don't know how the body grows, nor actually how it knows to grow. we like to think its the DNA but we really don't have any evidence. It's silly to say it isn't, but we still don't know.

so yes, but unless a robot did it, no.

The closest thing to a firebreathing creature in nature that I know of is the bombardier beetle, which isn't very close at all.
Cows store some amount of methane in their bowels, but release it periodically rather than relying on it for self defense.
Your best bet then, would lie in breeding a beetle-cow superhybrid, who when threatened faced the attacker and burped out a large amount of methane while igniting it with chemicals in an exothermic reaction.
There would be a chance of kickback, so keep behind the safety glass at all times.

I agree with 9. It will take many years of genetic engineering on different reptiles. Although they would not be able to get it pefectly in place it would be a useless experiment that will cost alot of money to sustain for a creature that is capable of killing a human?

>>13 it would be a useless experiment that wll cost alot of money

ahem, Iraq.

Anyways, what if the dragon spit out chunks of phosphorus with the methane?  Would that work?

>>14
could be

god killed  them through noah

>>16
and they killed the mermaids

bad noah, bad god...damnit, why kill sexy fish women?

Don't call me gay, but I need some mary jay!
