DE-EXTINCTION 

Professor George Church and his team, the Harvard Woolly Mammoth Revival team, have been recreating the blueprint of the mammoth for the past two years from DNA preserved in the Arctic permafrost. They hope to create a mammoth-elephant hybrid and hope to grow the embryo in an artificial womb. Woolly mammoths can help prevent the tundra permafrost form melting and releasing greenhouse gases by stomping on snow and allowing cold air to come in.

The scientists plan to create a hybrid with a cloning techniques, placing the reprogrammed nuclei into altered elephant egg cells. Additionally, they are using CRISPR, the genome-editing technology to alter the mammoth traits.
