Woolly Mammoth DNA Inserted Into Elephant Cells

Harvard geneticist George Church and his colleagues used a gene-editing technique known as CRISPR to insert mammoth genes for small ears, subcutaneous fat, and hair length and color into the DNA of elephant skin cells. The work has not yet been published in a scientific journal, and has yet to be reviewed by peers in the field.
Woolly mammoths, or Mammuthus primigenius have been extinct for millennia, with the last of the species dying out about 3,600 years ago.
Scientists say it may be possible to bring these and other species back from the grave, through a process known as de-extinction.
Church explained that splicing mammoth DNA into elephant cells is only the first step in a lengthy process.
Next, they need to find a way to turn the hybrid cells into specialized tissues, to see if they produce the right traits and correct features.
