bringing back the old onew may be a problem we cant overcome soon with DNA, or lack of DNA

but

how about a different approach ?

think maybe we could unlock the growth gene ?

do animals have a growth inhibitor, that stops them from growing when they reach an about average size ?

is there a way to shut that off ?

so instead of bringing back an old dino, we just create new ones

maybe a crocodile 200 times normal size ?

dought it

*doubt

and why ?

I suspect that the growth inhibitor is so deeply engrained in animals and humans that we could never restrain it. We could mess with the gland which controls growth, pituatary gland I believe.

I don't think we 'should' or 'need' to make anything bigger, tougher, meaner, etc. I do think that evolution does a fine job of it and have it take years to change things.

I don't think we should bring anything back from the past such as dinosaurs either. I don't think our current global climate would much support a creature that survived 65+ million years ago.

that may be true

but curiosity gets the best of me

maybe we could even grow a Great White to the size of a Megalodon



i do agree with that

the climate is very changed since then

GH...Growth Hormone. Over-production of GH in humans causes Giantism... so it will work on animals...but probably not 200 times, maybe just less than twice...

"Great whites average 12-16 feet long (3.7-4.9 m) long. The biggest great white shark on record was 23 feet (7 m) long, weighing about 7,000 pounds (3200 kg). Females are larger than males, as with most sharks. Shark pups can be over 5 feet (1.5 m) long at birth. "

just less then half eh ?

so maybe a 40 foot great white, yeah that would be something to see

So? The average human is 5'9" Some can grow to almost 7'. Its diversity, not GH. Humans with Giantism can reach up to 9'...


Yes, what you posted had no relevancy

you said GH could make it grow to almost 2 times the size

what i posted stated a Great White can be 23 feet long

so

therefore

a 40 foot Great White hopped up on GH would be almost 2 times the size

where is it you dont understand ?

......... ooops!

Sorry et...My mistake...I didn't understand you the first time

you do realize that even if you could make some thing grow 200 times it size it would die pretty quick the body structure would not be abel to support it.

Ok, why someone would want to bring Dino's back is beyond me. Why don't we just be happy we're alive and live life dammit.

Ravinar has raised an interesting point. If, for example, a chicken was engineered to grow 200 times it's normal size, it would be over 200 feet tall, and its legs would surely snap under the strain of trying of support such a heavy body, right?

In water it could...

of coarse. even t.rex had to go through a lot of evolutionary body modifications to support its larg size

what good is 200 ft chicken i water? other then being shark bait of coarse

this is a BIT off topic, but not really, but still it is... loll, but anyway... i am just wondering why the dinos were so huge, and now the biggest land animal is a wimpy 10- 20 foot tall (just guessing) elephant. i like the image of huge animals roaming the earth.. why are we so small?

The short answer to that Rambo is simply the demands of the environment. Why are whales so big, why are mice so small, why were the dinosaurs so massive and mammals much smaller? All demands of the environment and, naturally, evolution is not but adaptation to an environment. Some dinosaurs needed to have especially massive necks to reach vegetation high high up, and they needed an equally long tail to balance out, and as such a powerstation was needed between the neck and tail to control everything and keep such an immense body warmed and full of energy. Such large herbivores demanded therefore large predators too. The mammals took the small spots and stayed small so they could hide in tiny places and avoid big jaws. etc etc etc etc

And the Giraffe is currently the biggest land-dwelling mammal.

And it is 28 feet tall.

A animal with large proportions could support its weight in water. That's what I mean, Ravinar.

i know what you ment frogfish. i was just joking around that all.

The reason is that mammals have fur and warm blood, so they don't need to be as massive as reptiles to keep themselves warm.
The lizard-like dinos probably were cold-blooded so they needed to be as large to preserve their heat.

oh, ok

i dont see the problem

a 200' tall chicken wouldnt still have its little wimpy chicken legs

the legs would also grow in proportion

think how many people you could feed with a 200' chicken

even so the design of the hole body is not right for supporting such a larg body thats what i ment about t.rex it hade to chang its hole body structure to become so big theres a lot more to it then just making it grow really big

seems we may have to agree to disagree

i would think my theory would be like midgets

see a 3' tall man and it seems youre saying he couldnt possibly maintain his form or body style and be a 7' tall man

and yet we know it works


(yes, i understand Yao Ming isnt 200 times the size of a midget, but i still think it would work)

pulled this from a site i tells a little more clearly what i ment.


Dinosaurs are a group of ancient reptiles that had a set of particular skeletal features. The hips, hind legs, and ankles were specialized and allowed the legs to move directly under the body, rather than extending out from the side of the body as in modern lizards. This arrangement enabled dinosaurs to bring their knees and ankles directly below their hips and provided the necessary attachments for very strong leg muscles. Dinosaur skeletons were well designed for supporting a large body, for standing erect (upright), and for running. The front legs were adapted for grasping prey, for supporting weight, or for walking and running. The skulls of dinosaurs were designed for maximum strength, for minimum weight, and (in some cases) for grasping, holding, or tearing at prey. These skeletal features separated dinosaurs from other ancient reptiles such as Dimetrodon, the plesiosaurs, and pterosaurs.

Funny, because I remeber reading somewhere that if you double a creature's size, it would be around 4 times as heavy. Now, the skeletal structure to support a creature of that size would neet to me much more than twice as thick, correct? Would there even be enough room in the skin for muscle and tendon?

And your analogy reguarding the 3' man and the 7' man wouldn't work. The average height of a Homo Sapiens is between 5 and 6 feet, so a 7' person wouldn't put much strain on the human body structure.

also, your idea on midgets are at opposite ends of a genetic mutation- Giantism and dwarfism.

i stand by the idea that a 200' chicken would work

you offer no proof that it won't

hell they have 7' ostriches

go ahead, argue it's not a chicken

point is, it's a bird much larger then a chicken, much more then 4 times the size

I guess it could....The only ? I have are the legs. Would they be strong enough to hold it up?

Ostriches have very strong legs.

ok man!! i'm going to try this ONE MORE TIME!! the reason that a 200ft chicken would not work is because the body structure would not support it!! if your trying to compare a chicken to an ostrich it wont help your argument at all because as any biologist would tell you the chicken evolved to support a small body and an ostrich evolved to support a larger body. a chickens body structure could not support the wait of a 200ft body. i hope i made myself clear this time.
