In fact, to move at any speed the polar bear uses twice as much energy as do most other mammals.

With more data, team members hope to learn more about the distribution of krill under the frozen seawater and the details of penguin behavior.

However, the latest research on 3.2-million-year-old A. afarensis fossils suggests that the species may have been monogamous.

In the ancient city of Kamakura, Kanagawa Prefecture, alien species such as raccoons and Taiwan squirrels are causing damage to historical structures and gardens.

The snow leopard is listed by an international organization as “endangered” on its Red List of Threatened Species.

Lee Berger, the leader of the team and a professor at the University of the Witwatersrand in South Africa, said that this species may be one of the oldest of the genus Homo and may have lived in Africa about three million years ago.

They have finally sequenced 2.83 billion DNA letters with very high accuracy and made clear that humans have about 32,000 genes.

To survive, the polar bear must keep its body at the right temperature and store enough energy to last between meals that could be a few days or a few months apart.

The governor of Aichi, Kanda Masaaki, said, "The mammoth appeared in the frozen soil as a result of global warming. It's an environmental problem and this is part of the Expo's theme."
