Filling Pleistocene Park with giant herbivores is a difficult task because there are so few left. When modern humans walked out of Africa, some 70,000 years ago, we shared this planet with more than 30 land-mammal species that weighed more than a ton.

Currently, Pleistocene Park consists of an enclosed area of 20 square kilometers that is home to 8 major herbivore species: reindeer, Yakutian horse, moose, bison, musk ox, yak, Kalmykian cow and sheep.

Siberia
Pleistocene Park (Russian: Плейстоценовый парк, romanized: Pleystotsenovyy park) is a nature reserve on the Kolyma River south of Chersky in the Sakha Republic, Russia, in northeastern Siberia, where an attempt is being made to re-create the northern subarctic steppe grassland ecosystem that flourished in the area …

Predators of the Pleistocene Park. Several species of predatory mammals live in the Nizhnekolymsky district: polar bear, brown bear, arctic wolf, wolverine, lynx, red fox, arctic fox, sable, ermine. Of these, brown bears, wolverines, foxes, foxes, sables and ermines are present in the Park.

tundra
Trees and shrubs would also have penetrated to these places, but they were not the dominant vegetation cover (Sher 1997). It is only during the last interglacial, in the Holocene, that the mammoth steppe has vanished. Instead it has been replaced by moss forest and tundra. Many lakes and wetlands have appeared.

Cloning is a commonly suggested method for the potential restoration of an extinct species. It can be done by extracting the nucleus from a preserved cell from the extinct species and swapping it into an egg, without a nucleus, of that species’ nearest living relative. Cloning has been used in science since the 1950s.

Ecological and evolutionary implications Pleistocene rewilding could “serve as additional refugia to help preserve that evolutionary potential” of megafauna. Reintroducing megafauna to North America could preserve current megafauna, while filling ecological niches that have been vacant since the Pleistocene.

There are some species that are extinct that before the last individual died, living tissue was taken and put into deep freeze. So it’s able to be brought back as living tissue. The only way extinct species could be brought back is if there is living tissue that’s going to be found.

Pleistocene Park was founded by Sergey Zimov, a well known Arctic ecologist. Over his scientific career he published multiple scientific papers including five articles in Science Magazine as the first author.

Meet Five ‘Extinct’ Species That Have Returned to Life

• Elephant Shrew. The last time anyone recorded a sighting of the Somali elephant shrew was almost 50 years ago, after which, it was assumed to have become extinct.
• Terror Skink.
• Cuban Solenodon.
• Bermuda Petrel.
• Australian Night Parrot.

List of Advantages of Cloning Extinct Animals

• Bringing back an extinct animal can offer important scientific knowledge.
• Cloning an extinct animal signals a huge step in genetic engineering.
• Bringing extinct animals back can help the environment.
• The exploitative nature of man will likely kick in.
