Some of the scientists aiming to 'bring back' the woolly mammoth originally wanted to do it using 40,000-year-old cells

Picture this: A beast with most of the features of a woolly mammoth (think long, shaggy hair, plus special adaptations to sub-zero temperatures, like subcutaneous fat and specially-adapted blood) plus a few elephant-like traits (like a slightly longer body).

Nope, it's not your Pottermore Patronus.

It's the animal that a team of Harvard scientists hopes to create (or "bring back" as some advocates of the controversial practice known as de-extinction might say). And they want to do it in the next few years by combining the DNA of an elephant and a woolly mammoth using the gene-editing technology Crispr.

The team introduced their idea for the "mammophant," better known as "an elephant with a number of mammoth traits," at the American Association for the Advancement of Science annual meeting in Boston this week. They said it could be a reality by 2019.

Scientists have been talking about resurrecting the woolly mammoth, which went extinct thousands of years ago, for years, but the 2013 discovery of an astonishingly well-preserved mammoth carcass — complete with ancient blood — jumpstarted much of the excitement about the idea.

Here's a look into how they aimed to create a "mammophant" in 2014, before Crispr was a thing.

When a group of scientists heard rumors that the remains of a long-extinct mammal had been unearthed from the frozen ground on an island in northern Siberia, they rushed to the scene to see for themselves.

Yet as they arrived, the only evidence scientists found of an ancient beast lurking somewhere beneath the ground were parts of two giant tusks poking out of the icy Earth.

Over the next three days, as the ice surrounding the carcass slowly began to thaw, the scientists realized what an exciting find they had come across. The surprisingly well-preserved bones, muscles, teeth, and even some blood told the story of a woolly mammoth, a gargantuan beast that roamed the frosty tundra some 40,000 years ago.

As they unearthed the animal, dark red blood oozed out of the carcass. Three of its legs, most of its body, and even part of its head and trunk were still intact. Scratch marks on the bones revealed a grisly death — the animal was trapped in a peat bog and eaten alive by wolves.

Using carbon dating, the researchers determined that the mammoth, whom they nicknamed Buttercup, was alive some 40,000 years ago. Buttercup’s ancestors first evolved around 5 million years ago but went extinct about 4,500 years ago as the earth began to warm.

Unearthing the animal’s sizable teeth, for example, helped the researchers determine that Buttercup was no spring chicken when she died. Already in her mid-50s, the animal could probably have expected to live only another 15 years at the most.

Scientists managed to get a few ounces of blood from Buttercup’s body. It no longer contains blood cells — they’ve been destroyed by age and time — but it still holds Buttercup’s hemoglobin, the molecule her blood cells used to carry oxygen throughout her body. Mammoths had a special type of hemoglobin designed to keep their blood flowing in icy cold temperatures.

Natural History Museum of London paleobiologist Tori Herridge helped examine Buttercup. The Mammoth stood about 7 feet tall and weighed about 10,000 pounds, or about as much as an Asian elephant.

The mammoth also had a pretty large tongue, which she used to chew meals of grasses and high-protein wildflowers called forbs. Scientists think that when these plants died out about 10,000 to 15,000 years ago, their absence helped drive Buttercup’s relatives extinct.

Buttercup also used her teeth to chew. The lighter-colored lines show the outer edges of the teeth. Based on their condition, scientists determined that she was probably not in the best of health when she died.

Others, including Herridge, have raised concerns about that idea. “Who is responsible for the mammoth that is produced? Is it them? Is it the wider world? Do we get a say in if they’re doing it in the first place?” she said in the 2014 video.

Hwang said in 2014 that he hoped to use basically the same technique to create a living woolly mammoth. He would retrieve one of Buttercup's cells from her skin or muscle. The cell's DNA would be transferred into a DNA-free egg cell and replicated via electrical shocks. The new group of cells would be implanted in a surrogate mother, possibly an elephant. Hello, woolly mammoth baby.

If they couldn't find enough DNA inside Buttercup, Harvard geneticist George Church said he wanted to combine her genes with those of an elephant to bring a version of the ancient beast back to life. This controversial idea, called de-extinction, is the one brought up at the recent meeting. In the past it has polarized scientists, with some believing it could restore damaged ecosystems and others who think it could destroy them.
