The answer depends on what type of extinct you mean. (This may seem like a no brainer, there's only one type of extinct right? No.) A species may become functionally extinct, locally extinct or just plain extinct. If a species is functionally extinct it lacks the genetic diversity in the remaining members of it's species to continue reproducing viable offspring (due to inbreeding depression). This is an extreme example of population bottle neck. Generally what happens in this scenario is random mutations will become more common and any further reproduction will most likely produce individuals either infertile or unsuitable for further reproduction. This type of extinction is hard to reverse since efforts to increase genetic diversity in a population require that population to be outbred to another group. A locally extinction (whether just plain or functional extinction) can easilly be reversed with the introduction of non-local populations or members. (This may not suffice for some due to the differences in local populations due to the process of speciation.) Now the just plain extinct are in a world of hurt as far as recovery goes. there is obviously no breeding program that can bring back a just plain extinct (I.E no remaining individuals of the species alive) species. Through genetic research and cloning programs we may be able to bring back a select few species with well preserved tissue samples; but even still without a close surviving relative (like the mammoth and modern elephants for instance) we have only succeded in creating a functionally extinct animal from a just plain extinct one. In response to some of the other posts on this question: I don't think you should relie on god or nature to bring back a species. It hasn't happened yet, is not currently happening and never will. If allow ourselves to believe a species can be saved through some miraculous means then we open ourselves to justifying non-intervention. Hopefully that was short and sweet enough for you.

Yes ...its possible ... the nature, the world drama and god are very powerful .... which even science can't reach.

The science on which we are moving now is not holistic in its whole sense. Most of the theories are just based on some proposals, since those theories can't be objucted logically they are continuing ...
The question actually is - does all the animals which were claimed by scientists as once existed, are really existing?

Even if they are pronounced as extincted, there are always possibilities of alive if at all they existed

No. That's why they're called extinct.

Although there have been a few instances where animals *thought* to be extinct have appeared, such as a species of crocodile, a type of rhino, a few birds.

they die in higher numbers than they reproduce till there are literally a very small variety left, everywhere. numerous innovations that may ensue. a million) killed too a lot by using different issues (typically guy) 2)habitat the position they could stay is destroyed, reducing area the position they could stay 3) some thing they want for nutrition receives wiped out different innovations too. maximum species ultimately die out, the picture of persons. rather properly the nature of life. for sure, this is not needed for guy to assist that ensue lots swifter than nature taking its favourite route, and it really is fairly stupid human beings to do this to issues we may opt to keep round for our own egocentric desires.

Sure. Just look at the Dodo in the White House.

yes....through the thousands of years of evolution it took the first time.
