What is De-Extinction and How is it Done?
1. Map the extinct animals genome
2. Determine how the extinct animals genome is different from the genome of the closest living anccestory - and change the genome accordingly
3. Artificially inseminate the extinct animals genome and the new germ cell into the closest living ancestor.
4. The new germ cells will grow, techniques will need to be developed to make sure that th germ cells populate the gonads.
5. A hybrid will be born.
6. Two hybrids will mate and will reproduce an animal such as the extinct animal.
Debates about De-Extinction
Natural selection selects animals that have good adaptations, correct niches and have variation to survive over time and develope. Once an animal fails to have these benchmarks - they get extinct and make space for a new species, while other animals that meet these benchmarks create offsprings and survive over time. A lot of animals have gone extinct - and those animals who have gotten extinct, have gotten extinct for a reason. These animals didn't adapt to their new environments and therefore died out. If we would bring back these animals they would not only need more space and recources - but they would also need time to adapt to their new enviornment. Because the enviornment has changed throughout time - these extinct animals would not have the right adaptations or niches to continue living. Then the whole process would happen again, natural selection would pick animals - that scinetist have spent a lot of money on and time - to just die out and become extinct again. Also all living animals have already adapted throughout time to live without the extinct animals. If we would bring the extinct animals back - things such as food chains and ecosystems would corrupt.
Even now a days - animals are endangered and if scientists and the world can't keep those alive - how are we suppose to handel new species and keep both of generations alive if we already are driving 16,306 animals to extinction?
Why not Woolly Mammoths
One of the most famous candidates that are up for de-extinction are the Woolly Mammoths. If Woolly Mammoths would be revived they would probably be revived by the elephants. These days elephants are already having trouble to keep their population up because there isn't enough recources for them. If Woolly Mammoths would be revived then Elephants would have competition leading them to having less space and food, maybe even leading Elephants to extinction. As Woolly Mammoths would reproduce and create a bigger population - what would most likely happen is that the Elephants population would go down and these two animals would both fight for survival. Even though elephants are better adapted to the enviornment than the Woolly Mammoths, Woolly Mammoths are bigger than some elephants, and would need more food and space.
