Evolution Queen Anne Side Chair Spain and Portugal , 718 AD-Present. Spain, unlike Britain, never fell outside of history after the collapse of the Western Empire, which gives us a continuous record of rule from Rome through the Visigoths and beyond.Also, Spain underwent her own unique transformation in the trauma of the Islâmic conquest. The Visigoths were crushed and for almost three centuries a revived Christian kingdom. This was perplexing to the researchers, because common sense says that these mutations,

Ecosystems are in flux as rising temperatures affect where animals can live and how they behave. the researchers found.

speed." A week later, divers opened the rear hatch of the sub but found no survivors. It took salvagers two years, but the Kursk and her two nuclear reactors was raised. The Kursk was the sixth nuclear submarine to have sunk since 1963. The others all came to rest on the ocean floor at depths of more than 4,500 feet, far below where most marine life lives.

Hydrothermal Vent and Cold Seep Communities. Life in the deep sea is relatively sparse compared to the epipelagic (euphotic) and intertidal zones, with two exciting, and relatively recently discovered exceptions — hydrothermal vent and cold seep communities.

What is biodiversity? Biodiversity underpins life on Earth, and refers to the variety found in biota from genetic make up of plants an animals to cultural diversity.

Marine biology is the scientific study of marine life, organisms in the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean. The exact size of this large proportion is unknown.
