EmagGeek shares a report: Scientists have genetically engineered mice with some key characteristics of an extinct animal that was far larger -- the woolly mammoth. This "woolly mouse" marks an important step toward achieving the researchers' ultimate goal -- bringing a woolly mammoth-like creature back from extinction, they say.

"For us, it's an incredibly big deal," says Beth Shapiro, chief science officer at Colossal Biosciences, a Dallas company trying to resurrect the woolly mammoth and other extinct species. The company announced the creation of the woolly mice Tuesday in a news release and posted a scientific paper online detailing the achievement. Scientists implanted genetically modified embryos in female lab mice that gave birth to the first of the woolly pups in October.

My editorial: One has to wonder why it is necessary or even a great idea to bring back species that nature long ago determined were a failure.
