Question

What animal can become extinct then come back again-and its not a pheonix?

Answer 1

I'm going with egg laying creatures.  Those that lay eggs which do not require maintenance from the parent.  It's possible for such a species (like the aforementioned fish) to completely die out whilst leaving fertilized eggs behind which will hatch.

That is, of course, dependent on your definition of life.  Is a fertilized egg alive?

Answer 2

It seems impossible.   You could be talking as a riddle or a trick question.  Offhand, the best answer I can give, is to use cloning technology, and have a similar animal give birth the the clone.  In that way, an 'extinct' animal can be reborn.  I think that I read about two years ago, a rare cow-like animal, was birthed by a regular cow, when the animals through in vitro fertilization resulted in a fertilized egg, then implanted in a cow, which gave birth to a completely different species.  There's SOME talk that if ever there could be some non-degraded Wooly Mammoth DNA were to be located in some iceberg, that a clone could be created, and that a regular elephant could give birth.  That would be amazing.

Answer 3

yeah... what reflux said.

Answer 4

There is a type of fish that lives in the desert - it hatches from eggs, grows to maturity, lays eggs (& fertilses them) and dies all during the time that the short heavy rains occur.

IT is extinct in the wild during the dry periods - although no doubt there are some living to incredible old age in captivity!

Answer 5

None.  You are not using the word properly.  Extinct means gone forever.

There are animals that have periods that might seem like death.  However, they or their reproductive products are just waiting for the correct conditions to restart their life cycles.

It seems, using your way of thinking, every plant that produces a seed then dies back for winter would be going extinct.  That just does not happen.

Answer 6

An ***. If a donkey does the nasty with a horse, you get an ***, no?

Answer 7

Something like the lungfish? Lies 'dormant' until rains come again the following year?

Answer 8

None, unless its a trick question. Then I would have to go with the Ceolocanth (sp?) It is a fish from the time of the dinosaurs, it was believed to be extinct and then it was rediscovered somewhere  in Africa or off its shores by some local fishermen.

Answer 9

As above I think the best answer would be a mule (***).. Product of a donkey mating with a horse.  They could be all gone but as long as there are still donkeys and horses around....

Answer 10

Maybe you mean "annuals" like annual plants that all die in winter and the seeds come back. Some of the folks above mentioned some "annual" animals, some killifish and maybe brine shrimp and some insects.

Answer 11

Yup..hybrid is the key..although the female of the species IS usually fertile and can 'back fertilise' with a 'parent' male of either of the two species.

..It would be interesting to specul8 if this happened during evolution..

Answer 12

Some archeologists believe they can bring back a species of Dinosaur from the DNA of a dinosaur skeleton recently found. By the way, the Phoenix was a mythological bird that rose from the ashes in ancient greek stories. It never really existed.

Answer 13

None. Extinct means it cant come back.

Answer 14

Tasmanian Tiger and the Miss Waldron's Red Colobus.

Answer 15

when an animal is truly extinct (meaning all of it kind are dead). then there is no possible way is could come back in to existence's.

Answer 16

Johnstonemac gives a very interesting response. He uses mules as an example, but it could apply to any hybrid.

For example, there is a species of salamander in California that has diversified into separate sub-species, with different coloration and body shape depending on the environment.

Two of these subspecies live in neighboring environments, but one is blackish purple with yellow spots (camouflage), and the other is bright orange mimicking a poisonous species of salamander.

The two subspecies have interbred creating a third subspecies which has both orange and dark areas with spots, making it neither a good mimic nor a good camouflage, and it is thought this subspecies will eventually die off.

However, if the subspecies becomes extinct, there is still the opportunity for it to arise again if the orange and spotted subspecies again interbreeds.

I think "hybrid animals" is a good answer.

Here's a video on the salamanders: http://www.pbs.org/wgbh/nova/id/extr-evo...

Answer 17

I don't get this. If an animal is extinct there is no way back.

Please explain.
