Scientists at University of California, Santa Barbara recently have published a scientific paper in the journal Functional Ecology, examining ecological advantages, responsibilities and risks after resurrecting an extinct species and introducing it to modern ecosystems.

Researchers at UCSB team offered guidelines for restoring ecological function through de-extinction. They advise how to make it more successful and how to avoid creating 'eco-zombies'. Eco-zombies are resurrected, once extinct species which no longer have any ecological function in modern world.
The guidelines are divided into three criteria:
- The first proposes resurrecting recently extinct species rather than one which disappeared thousands of years ago. These types of species may fit more harmoniously into modern ecosystems, because there has been less time for changes to occur, since their extinction.
- The second criterion proposes selecting species whose ecological function are undoubtedly irreplaceable.
- The third guideline is to resurrect species that can be restored to "functionally meaningful abundance levels". It means having enough individuals within ecosystem to be able to perform their functions good enough to affect the ecosystem.
Instead of opposing the idea of de-extinction, the scientists from UCSB attempt to initiate a conversation within the scientific community about how to make this procedure more ecologically sustainable.
Scientists have already, succesfully managed to clone some of the extinct species.
