Colossal aims to restore ecological balance by reintroducing "keystone" species to their original habitats. By reviving these animals, they hope to slow climate change—for example, by having woolly mammoths restore the Arctic grasslands to prevent permafrost melt.
Rather than simple "cloning," Colossal uses a "de-extinction toolkit" to edit the DNA of a living relative to match an extinct ancestor.
