   We included seals, whales, elephants, mice, hummingbirds. We have dinosaurs of different sizes, extinct marine reptiles like mosasaurs and plesiosaurs. We have animals that weigh several tons, and animals that are just a few grams. The spread is very big.

   We are unlikely to get the full genome sequence of the extinct species, thus we will never be able to fully recreate the genome of the lost form. There will always be some parts that can't be changed, they will have to cherry pick what changes to make. And thus the result will be a hybrid.

4. Jelle Wiersma:

5. Andrew Pask:

   The technologies we are developing to de-extinct the thylacine all have immediate conservation benefits -- right now -- to protect marsupial species. Biobanks of frozen tissue from living marsupial populations have been collected to protect against extinction from fires, however, we still lack the technology to take that tissue -- create marsupial stem cells -- and then turn those cells into a living animal. That is the technology we will develop as a part of this project.
