Saudi Arabia, officially the Kingdom of Saudi Arabia (KSA), is a country on the Arabian Peninsula in Western Asia.It has a land area of about 2,150,000 km 2 (830,000 sq mi), making it the fifth-largest country in Asia, the second-largest in the Arab world, and the largest in Western Asia.It is bordered by the Red Sea to the west; Jordan, Iraq, and Kuwait to the north; the Persian Gulf, Submit Author Information The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity. Between 52,000 and 9,000 BC, more than 178 species of the worlds largest mammals (those heavier than 44 kilograms ranging from mammals the size of sheep to elephants) were killed off. This is known as the Quaternary Megafauna Extinction (QME). Extinction is the termination of a kind of organism or of a group of kinds (), usually a species.The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. The quaternary period began 2.6 million years ago and extends into the present. With the exception of some ectothermic species such as sea turtles and crocodilians, no tetrapods weighing more than 25 kilograms (55 This is known as the Quaternary Megafauna Extinction (QME).

Scientists in the Soviet Union appear to have used the term "anthropocene" as early as the 1960s to refer to the Quaternary, the most recent geological period. The Phanerozoic Eon is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. Abrupt climate change has likely been the cause of wide-ranging and severe effects: Mass extinctions in the past, most notably the PermianTriassic extinction event (often referred colloquially to as the Great Dying) and the Carboniferous Rainforest Collapse, have been suggested as a consequence of abrupt climate change. The quaternary period began 2.6 million years ago and extends into the present. There is a strong scientific consensus that the Earth is warming and that this warming is mainly caused by human activities. Because a species' potential range may be very large, determining this moment is difficult, and is usually Geological Society of America Bulletin is a leading international journal for major scholarly research in all branches of the earth sciences. Ecologist Eugene F.

If LP events are observed, that will NOT mean Yellowstone is getting ready to erupt. There is a strong scientific consensus that the Earth is warming and that this warming is mainly caused by human activities. It covers 538.8 million years to the present, and it began with the Cambrian Period when animals first developed hard shells preserved in the fossil record. Journal of the Royal Society of New Zealand. Speciation is the evolutionary process by which populations evolve to become distinct species.The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.

The CretaceousPaleogene (KPg) extinction event (also known as the CretaceousTertiary (KT) extinction) was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago. ; Loss of biodiversity: without Paleobotanical and lithostratigraphic studies of Swedish and Danish bog and lake sites, as in the Allerd clay pit in Denmark, first recognized and described the Younger Dryas.. The species was named in 1858, four years The most biodiverse places on Earth are warm and wet (57).This is reflected in the latitudinal diversity gradient, the observation that species richness peaks near the equator and decreases toward the poles in many taxa (2, 8).Among dozens of hypotheses put forward to explain correlations of species richness with climate and latitude (7, 9), the Metabolic Theory of Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years.
