If tools like CRISPR allow us to replace keystone species like the woolly mammoth and passenger pigeon in order to keep greenhouse gases in the tundra or to restore healthy ecosystems then we should use them.

Unlike Band-tailed Pigeons which will nest in densities of one nest per three to four acres Passenger Pigeons nested in densities of up to 100 nests per tree. 3 Allele replacement for precisely hybridizing a living species with an extinct species is the new genome-editing technique developed by George Church. Although passenger pigeons were the victims of human hunters we still dont understand precisely how a species can decline from billions to none within a period of fifty years.

Passenger pigeon Ectopistes migratorius migratory bird hunted to extinction by humans. The passenger pigeon or wild pigeon Ectopistes migratorius is an extinct species of pigeon that was endemic to North America.

The mean nucleotide difference d xy between the genomes of the passenger pigeon and the domestic pigeon was 0028The genetic distance between the genomes of two passenger pigeons from the western part of their breeding range d xy 00036 was similar to those between either of them and one from the eastern part d xy 00034 and 00039 suggesting no population structure in this species. Billions of these birds inhabited eastern North America in the early 1800s. Similarly the European aurochs extinct since 1627 helped to keep forests across all of Europe and Asia mixed with biodiverse meadows and grasslands.

They drove the ecosystem were pursued by a huge suite of predators including Native Americans and were of such numbers 3-5 billion birds they were a dominating force which must have manipulated their ecosystem with a randomness as variable as their vast and sky-blackening migrations see Wilson 1812.
