Lazarus Project Recreates Extinct Australian Frog

Lazarus Project Recreates Extinct Australian Frog:
The Lazarus Project team says they have been able to recover cell nuclei of the extinct gastric-brooding frog, Rheobatrachus silus,

from tissues collected in the 1970s and kept for 40 years in a conventional deep freezer.


The genome of

Rheobatrachus silus, extinct since 1983, has been revived and reactivated by a team of scientists using

somatic cell nuclear transfer

to implant a "dead" cell nucleus into a fresh egg from another frog species.


Rheobatrachus silus is famous for swallowing its eggs, brooded its young in its stomach and giving birth through its mouth. The "de-extinction" project aims to bring the frog back to life.
