It's a shame that clones have shorter life span and have such a high risk of death/failure at living... how ever if the clone lives long enough to produce an off spring then the off spring will remain healthy and have a normal lifespan.

funny how that works

they could be put in a cold environment brah

isnt that what this thread is about

edit: if we're only talking about selective breeding this probably wouldnt work all that well

edit: id like to reinstate the fact taht i dont know what im talking about

i should put a disclaimer in my sig or something

i'm saying they'd have trouble with it for reasons like that

Mammoths and Mastodons were both Pleistocene Mega fauna, thats why they're so bad ass.

If it would be unreliably hard to maintain the environment and diet of a species for long enough to see it transform into a mega fauna, what if you alter the genes of an embryo (i have no idea what im talking about) so it activates some sort of "gigantism gene" and place it in an egg, when its born you should have a giant creature within 1 generation right?

but it wouldn't necessarily be a new species of mega fauna it would just have a genetic "disorder" so to say?

lets talk a little more about biology and cross species breeding, humans and chimps can't create an off spring, this is because of a difference in the number of chromosomes. Lions and Tigers have been successfully bred to create Ligars but the cross species animal can not create a baby of its own.. What if we found a way to match chromosomes of 2 different species, one large and one small, could we use selective breeding to take the trait of the large animal and apply it to the small one to make it large?

Sorry for my silly/ungodly talk of cross species breeding im sure many of you think its wrong lol. If any body has some other sort of question or hypothetical genetic/breeding scenario please ask I like to read and discuss about these sort of topics.

Well, we do know what genetic disorder causes gigantism in humans, so theoretically it would be possible to breed an animal with a such defect. Humans with this effect only grow up to 50% larger than average though, so there's a limit to it.

I doubt that it would be unreliably hard to maintain a suitable environment for whatever species we choose though, as long as we take one that isn't too needy. We've got polar bears and penguins living in zoo's all around the world, though the climates are often a lot different than in their original habitat. We don't have to replicate the exact circumstances as they would be in the wild, as long as we meet those that are required for the animal's health and the breeding proces.

Indeed it would. It's quite hard to draw a line as to where one species ends and the other begins, but one of the most solid criteria is wether cross-breeding the two would give fertile offspring as a result. If so, they're still the same species, if not, they're seperate species. Since gigantism doesn't affect reproduction abilities, they'd be perfectly capable of succesfully mating with their non-giant peers. You could, however, make sure they only breed with other giants, which in the end would result in the giants and non-giants becoming two seperate species due to divergent evolution.

I doubt wether we'd actually be able to do this, since there are so many problems with combining genetic material of two species that are significantly different, but if we somehow could then I guess it would be possible.

Anyone who thinks cross-breeding or selective breeding is wrong should not have dogs, or eat vegetables and fruits, or buy flowers, since they're mostly the results of doing exactly that.

As humans can we use natural selection to breed giant animals? Naturally I look at the evolution of dogs (they mapped out the Canines Genome and found that all dogs come from wolves, after thousands and thousands and thousands of rounds of selective breeding we transformed a wolf into a chihuahua)

Theoreticaly, yes, we can use use selective breeding to increase the average size of pretty much any species, but the difficulty comes in the time it takes. Y'see, dogs are easy to use for selective breeding, they become fully adult at about 3 years, at which point they have grown as much as they ever will, so at 3 years you can see the results of your selective breeding, but when we're talking about selectively breeding reptiles for size, other difficulties arise.

Many reptiles can live a long time pretty much the same lifespan as a human in many cases, and many reptiles also never stop growing throughout their lives, so whereas you can see the results of selectively breeding dogs for size within just 3 years, it could take a persons lifetime to see the results from just one generation of selectively breeding reptiles for size.

We can feasably do it, we can have a project that spans many generations of people and we could selectively breed giant lizards, but to what point? We couldn't release them into the wild because they would be damaging to the ecology that has evolved since giant lizards became extinct, they'd be seriously dangerous so keeping them in captivity would have it's problems too and those that become a part of such a program would never live long enough to see the results.

Unfortunately, because you told everyone your wish, it will never come true now. sorry mate

No, because the reason why animals grew so big was that there was more O2 in the air back then.
