Consequences of De-evolution

De-extinction

De-extinction is the process of bring a species back from being extinct. Although this has not been completely accomplished yet for more than 7 minutes, here the process that is currently being tested and experimented with:


  1. Find frozen or preserved DNA of the extinct animal

  2. Map the genome of the extinct animal

  3. Find the living animal that is closest to the extinct animal and determine the differences in their genomes

  4. Change extinct animals genome accordingly

  5. Artificially inseminate a surrogate mother of the currently living species with the old genome.

  6. The mother will then reproduce and create a hybrid

  7. Two hybrids will then reproduce with each other and therefore recreate a purebred of that species


If there is no possibility of a surrogate mother due to the extinct animal being too big or not close enough to any living species that could be used., scientists think it may be possible to create an artificial womb.

Throughout the years since these animals went extinct other species have adapted in order to fill their niche or advance it, therefore if you brought back those animals it could cause another group animals to go extinct. Also, it might add an extra predator to other species therefore causing them to die out as well.


For example bees are a very important factor in the world today, without them many types of plants - and therefore animals - would go extinct. Already bees have many predators who aim to eat the honey inside their hives, for example birds, small mammals, reptiles and other insects. Certain animals, if revived, could add another predator to the food chain that they are not adapted to fight of and avoid and therefore cause them to go extinct. This could then lead to many more problems in the world.

It is also very illogical to revive old animals who were adapted for the world as they knew it. Earth has changed since the time of the mammoths or pterodactyls and therefore their adaptations may no longer be valid and useful in the modern environment.Their instincts may be outdated, their defences useless against the more evolved predators. To bring back these animals would leave them ignorant and defenceless in a new environment that they are in no way suited for.


Not to mention that many environments themselves have changed and therefore many animals would not have enough resources or space to survive. For example arctic animals like the wolly mammoth would be added into a fastly evaporating climate and would struggle to survive with the other endangered animals like the polar bears.

Saber Toothed Cat

Another example of animal that could be brought back from extinction is the saber toothed cat. However, in its time it was the top of the food chain, and if it came back it could cause many other animals to go extinct in its place. Also would it even have an environment to come back to? The saber toothed cat lived in dense forest areas in both north and south america. However due to deforestation and human expansion they may not have a habitat to live in anymore.
