BRING­ING SPECIES BACK FROM THE DEAD ISN’T GOOD CON­SER­VA­TION

When it’s gone, you shouldn’t bring it back — even if you can. In an ar­ti­cle in the jour­nal Na­ture Ecol­ogy and Evo­lu­tion, Car­leton Univer­sity bi­ol­o­gist Joseph Ben­nett ar­gues so-called “de-ex­tinc­tion” would be a bad in­vest­ment.

It might be tech­ni­cally pos­si­ble to bring back species like the pas­sen­ger pi­geon. But do­ing so wouldn’t help, the re­searchers write. The vast re­sources spent on cloning ex­tinct an­i­mals and in­te­grat­ing them back into the en­vi­ron­ment could be bet­ter used to help liv­ing species, they write. That, and res­ur­rected species prob­a­bly wouldn’t fit back into their old niches.
