Galápagos Islands
The Galápagos Islands () are an archipelago of volcanic islands in the Eastern Pacific, located around the equator, west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with a population of slightly over 33,000 (2020). The province is divided into the Cantons of Ecuador, cantons of San Cristóbal Island, San Cristóbal, Santa Cruz Island (Galápagos), Santa Cruz, and Isabela Island (Galápagos), Isabela, the three most populated islands in the chain. The Galápagos are famous for their large number of Endemism, endemic species, which were studied by Charles Darwin in the 1830s and inception of Darwin's theory, inspired his theory of evolution by means of natural selection. All of these islands are protected as part of Ecuador's Galápagos National Park and Galápagos Marine Reserve, Marine Reserve. Thus far, there is no firm evidence that Polynesian expansion, Polynesians or the indigenous peoples of South America, Indigenous pe ...

Cantons Of Ecuador
The cantons of Ecuador are the second-level subdivisions of Ecuador, below the provinces. The cantons are further subdivided into parishes, which are classified as either urban or rural. As of 2025, there are 222 cantons in the country. The most recently created cantons are Sevilla Don Bosco in Morona Santiago Province in 2024; and La Concordia in Esmeraldas Province in 2007, although in 2013 La Concordia was transferred to Santo Domingo de los Tsáchilas Province.

Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salt (chemistry), salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral water, mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen water, frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ice pellets, sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranea (geography), subterranean subterranean river, rivers and underground lake, lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to sur ...

Indigenous Peoples Of South America
In South America, Indigenous peoples comprise the Pre-Columbian peoples and their descendants, as contrasted with people of European ancestry and those of African descent. In Spanish, Indigenous peoples are referred to as (), or (). The term () is used in Argentina, and () is commonly used in Colombia. The English term ''Amerindian'' (short for "Indians of the Americas") is often used in the Guianas. Latin Americans of mixed European and Indigenous descent are usually referred to as (Spanish) and (Portuguese), while those of mixed African and Indigenous ancestry are referred to as . It is believed that the first human populations of South America either arrived from Asia into North America via the Bering Land Bridge and migrated southwards or alternatively from Polynesia across the Pacific. The earliest generally accepted archaeological evidence for human habitation in South America dates to 14,000 years ago, and is located at the Monte Verde site in southern Chile. T ...

Polynesian Expansion
Polynesia ( , ) is a subregion of Oceania, made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are called Polynesians. They have many things in common, including linguistic relations, cultural practices, and traditional beliefs. In centuries past, they had a strong shared tradition of sailing and using stars to navigate at night. The term was first used in 1756 by the French writer Charles de Brosses, who originally applied it to all the islands of the Pacific. In 1831, Jules Dumont d'Urville proposed a narrower definition during a lecture at the Société de Géographie of Paris. By tradition, the islands located in the southern Pacific have also often been called the South Sea Islands, and their inhabitants have been called South Sea Islanders. The Hawaiian Islands have often been considered to be part of the South Sea Islands because of their relative proximity to the so ...

Galápagos Marine Reserve
The Galápagos Marine Reserve (GMR) lies a thousand kilometres from the Ecuadorian mainland and covers an area of around . The Galápagos Islands and the surrounding waters represent one of the world’s most unusual ecosystems and are rich areas of biodiversity. Recently granted UNESCO World Heritage Site status, the Galápagos Marine Reserve is the largest marine reserve in a developing country and the second largest reserve in the world. Snorkeling and diving In certain areas in the Galápagos Marine Reserve, it is possible for visitors to dive or snorkel, and many guests have come into contact with diverse aquatic species which live underwater: Whales, whale sharks, hammerhead sharks, rays, manta rays, swordfish and sea turtles, etc. Other habitats within the GMR are the rocky seabed, vertical rock faces, sandy beaches, mangrove swamps and, to a lesser extent, coral reefs. A popular spot is Tortuga Bay on the Island of Santa Cruz where there is a separate mangrove where the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galápagos National Park
Galápagos National Park () was established in 1959. It began operation in 1968, and it is Ecuador's first national park and a UNESCO World Heritage Site. Park history The government of Ecuador has designated 97% of the land area of the Galápagos Islands as the country's first national park. The remaining 3% is distributed between the inhabited areas of Santa Cruz, San Cristóbal, Baltra, Floreana and Isabela. In 1971, the Galápagos National Park Service had its first Superintendent, 2 officers and 6 park rangers on Santa Cruz Island. In 1974, the Galápagos National Park Service had its first management plan and a team of officials in accordance with the organic structure issued in 1973, with a Superintendent, 2 conservation officers, 40 park rangers to comply with management objectives. On Santa Cruz is the Charles Darwin Research Station. In 1979, UNESCO declared the Galápagos Islands Natural Heritage for Humanity, making the Park Service through the Superinte ...

Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the Heredity, heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with selective breeding, artificial selection, which is intentional, whereas natural selection is not. Genetic diversity, Variation of traits, both Genotype, genotypic and phenotypic, exists within all populations of organisms. However, some traits are more likely to facilitate survival and reproductive success. Thus, these traits are passed the next generation. These traits can also become more Allele frequency, common within a population if the environment that favours these traits remains fixed. If new traits become more favoured due to changes in a specific Ecological niche, niche, microevolution occurs. If new traits become more favoured due to changes in the ...

Evolution
Evolution is the change in the heritable Phenotypic trait, characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation. The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments. The theory was first set out in detail in Darwin's book ''On the Origin of Species''. Evolution by natural selection is established by observable facts about living organisms: (1) more offspring are often produced than can possibly survive; (2) phenotypic variatio ...

Inception Of Darwin's Theory
The inception of Darwin's theory occurred during an intensively busy period which began when Charles Darwin returned from the survey voyage of the ''Beagle'', with his reputation as a fossil collector and geologist already established. He was given an allowance from his father to become a gentleman naturalist rather than a clergyman, and his first tasks were to find suitable experts to describe his collections, write out his '' Journal and Remarks'', and present papers on his findings to the Geological Society of London. At Darwin's geological début, the anatomist Richard Owen's reports on the fossils showed that extinct species were related to current species in the same locality, and the ornithologist John Gould showed that bird specimens from the Galápagos Islands were of distinct species related to places, not just varieties. These points convinced Darwin that transmutation of species must be occurring, and in his ''Red Notebook'' he jotted down his first evolutionary ideas ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English Natural history#Before 1900, naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a Common descent, common ancestor is now generally accepted and considered a fundamental scientific concept. In a joint presentation with Alfred Russel Wallace, he introduced his scientific theory that this Phylogenetics, branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.. Darwin has been described as one of the most influential figures in human history and was honoured by Burials and memorials in Westminster Abbey, burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh Medical Schoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
