Giant meatball of extinct mammoth unveiled in The Netherlands

The meatball was created by Australian cultured meat company Vow which - promising this was not an April Fools' joke - said it wanted to get people talking about cultured meat, calling it a more sustainable alternative for real meat.

"We wanted to create something that was totally different from anything you can get now," Vow founder Tim Noakesmith told Reuters, adding that an additional reason for choosing mammoth is that scientists believe that the animal's extinction was caused by climate change.

The meatball was made of sheep cells inserted with a singular mammoth gene called myoglobin.

Since the mammoth's DNA sequence obtained by Vow had a few gaps, African elephant DNA was inserted to complete it.

The meatball, which has the aroma of crocodile meat, is currently not for consumption.

"Its protein is literally 4,000 years old. We haven't seen it in a very long time. That means we want to put it through rigorous tests, something that we would do with any product we bring to the market," Noakesmith said.

Vow hopes to put cultured meat on the map in the European Union, a market where such meat as food is not regulated yet.
