The Cenozoic is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterised by the dominance of mammals and angiosperms. It is the latest of three geological eras, preceded by the Mesozoic and Paleozoic. The Cenozoic started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor.
The PaleozoicEra is the first of three geological eras of the Phanerozoic Eon. Beginning 538.8 million years ago (Ma), it succeeds the Neoproterozoic and ends 251.9 Ma at the start of the Mesozoic Era. The Paleozoic is subdivided into six geologic periods :
The Phanerozoic is the current and the latest of the four geologic eons in the Earth's geologic time scale, covering the time period from 538.8 million years ago to the present. It is the eon during which abundant animal and plant life has proliferated, diversified and colonized various niches on the Earth's surface, beginning with the Cambrian period when animals first developed hard shells that can be clearly preserved in the fossil record. The time before the Phanerozoic, collectively called the Precambrian, is now divided into the Hadean, Archaean and Proterozoic eons.
The Nearctic realm is one of the eight biogeographic realms constituting the Earth's land surface.
The geology of Great Britain is renowned for its diversity. As a result of its eventful geological history, Great Britain shows a rich variety of landscapes across the constituent countries of England, Wales and Scotland. Rocks of almost all geological ages are represented at outcrop, from the Archaean onwards.
The BBC Studios Natural History Unit (NHU) is a department of BBC Studios that produces television, radio and online content with a natural history or wildlife theme. It is best known for its highly regarded nature documentaries, including The Blue Planet and Planet Earth, and has a long association with David Attenborough's authored documentaries, starting with 1979's Life on Earth.
The Future Is Wild is a 2002 speculative evolution docufiction miniseries and an accompanying multimedia entertainment franchise. The Future Is Wild explores the ecosystems and wildlife of three future time periods: 5, 100, and 200 million years in the future, in the format of a nature documentary. Though the settings and animals are fictional, the series has an educational purpose, serving as an informative and entertaining way to explore concepts such as evolution and climate change.
In biogeography, the Mediterranean Basin, also known as the Mediterranean Region or sometimes Mediterranea, is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation. It was a very important part of Mediterranean civilizations.
The geology of England is mainly sedimentary. The youngest rocks are in the south east around London, progressing in age in a north westerly direction. The Tees–Exe line marks the division between younger, softer and low-lying rocks in the south east and the generally older and harder rocks of the north and west which give rise to higher relief in those regions. The geology of England is recognisable in the landscape of its counties, the building materials of its towns and its regional extractive industries.
The island of Great Britain, along with the rest of the archipelago known as the British Isles, has a largely temperate climate. It contains a relatively small fraction of the world's wildlife. The biota was severely diminished in the last ice age, and shortly thereafter was separated from the continent by the English Channel's formation. Since then, humans have hunted the most dangerous forms to extinction, though domesticated forms such as the dog and the pig remain. The wild boar has subsequently been reintroduced as a meat animal.
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun, which also created the rest of the Solar System.
Wild Africa is a British nature documentary series created and produced by the BBC. It explores the natural history of the African continent. It was first transmitted on 7 November 2001 on BBC Two in the United Kingdom and comprises six episodes. Each concentrates on a particular environment. The producers use aerial photography and wildlife footage to show how natural phenomena such as seasonal changes influence the patterns of life. Wild Africa was produced by the BBC Natural History Unit and narrated by Fergal Keane.
Wild Down Under is a BBC nature documentary series exploring the natural history of the Australasian continent, first transmitted in the UK on BBC Two in September 2003. It was broadcast in Australia under the title Wild Australasia in February 2004.
Wild Caribbean is a four-part BBC nature documentary series exploring the natural and cultural history of the Caribbean Islands and Sea. It was first transmitted in the UK on BBC Two in January 2007. The series was produced by the BBC Natural History Unit and narrated by actor Steve Toussaint. This series also aired in Australia on ABC1 each Sunday at 7:30pm from 15 February 2009.
A marine regression is a geological process occurring when areas of submerged seafloor are exposed above the sea level. The opposite event, marine transgression, occurs when flooding from the sea covers previously-exposed land.
The First Eden: The Mediterranean World and Man is a BBC documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 8 March 1987.
All of the animals living in Asia and its surrounding seas and islands are considered the fauna of Asia. Since there is no natural biogeographic boundary in the west between Europe and Asia, the term "fauna of Asia" is somewhat elusive. Temperate Asia is the eastern part of the Palearctic realm, and its south-eastern part belongs to the Indomalayan realm. Asia shows a notable diversity of habitats, with significant variations in rainfall, altitude, topography, temperature and geological history, which is reflected in its richness and diversity of animal life.
Pangaea or Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ago, at the end of the Triassic and beginning of the Jurassic. In contrast to the present Earth and its distribution of continental mass, Pangaea was centred on the equator and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists.
The Neanderthals in Gibraltar were among the first to be discovered by modern scientists and have been among the most well studied of their species according to a number of extinction studies which emphasize regional differences, usually claiming the Iberian Peninsula partially acted as a “refuge” for the shrinking Neanderthal populations and the Gibraltar population of Neanderthals as having been one of many dwindling populations of archaic human populations, existing just until around 42,000 years ago. Many other Neanderthal populations went extinct around the same time.
Seven Worlds, One Planet is a documentary series from the BBC Natural History Unit. The seven-part series, in which each episode focuses on one continent, debuted on 27 October 2019 and is narrated and presented by naturalist Sir David Attenborough. Over 1,500 people worked on the series, which was filmed over 1,794 days, with 92 shoots across 41 countries.
