Hunter-gatherer
Forest gardening was also being used as a food production system in various parts of the world over this period. Forest gardens originated in prehistoric times along jungle-clad river banks and in the wet foothills of monsoon regions.[citation needed] In the gradual process of families improving their immediate environment, useful tree and vine species were identified, protected and improved, whilst undesirable species were eliminated. Eventually superior foreign species were selected and incorporated into the gardens.
What Darwin Didn't Know
What Darwin Didn't Know is a documentary show on BBC Four presented by Armand Marie Leroi which charts the progress in the field of Evolutionary Theory since the original publication of Charles Darwin's "On the Origin of Species" in 1859.
Survival of the fittest
Herbert Spencer first used the phrase, after reading Charles Darwin's On the Origin of Species, in his Principles of Biology (1864), in which he drew parallels between his own economic theories and Darwin's biological ones: ``This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called 'natural selection', or the preservation of favoured races in the struggle for life. ''
Sequencia
Sequencia is a monotypic genus of plants in the family Bromeliaceae. The sole species is Sequencia serrata (originally "Brocchinia serrata"), endemic to the Vaupés region of Colombia.
Evolution
In the mid-19th century, Charles Darwin formulated the scientific theory of evolution by natural selection, published in his book On the Origin of Species (1859). Evolution by natural selection is a process first demonstrated by the observation that often, more offspring are produced than can possibly survive. This is followed by three observable facts about living organisms: 1) traits vary among individuals with respect to morphology, physiology, and behaviour (phenotypic variation), 2) different traits confer different rates of survival and reproduction (differential fitness), and 3) traits can be passed from generation to generation (heritability of fitness). Thus, in successive generations members of a population are replaced by progeny of parents better adapted to survive and reproduce in the biophysical environment in which natural selection takes place.
Bird migration
Short-distance passerine migrants have two evolutionary origins. Those that have long-distance migrants in the same family, such as the common chiffchaff Phylloscopus collybita, are species of southern hemisphere origins that have progressively shortened their return migration to stay in the northern hemisphere.
On the Origin of Species
In January 1871, George Jackson Mivart's On the Genesis of Species listed detailed arguments against natural selection, and claimed it included false metaphysics. Darwin made extensive revisions to the sixth edition of the Origin (this was the first edition in which he used the word "evolution" which had commonly been associated with embryological development, though all editions concluded with the word "evolved"), and added a new chapter VII, Miscellaneous objections, to address Mivart's arguments.
Conservation biology
An example of an umbrella species is the monarch butterfly, because of its lengthy migrations and aesthetic value. The monarch migrates across North America, covering multiple ecosystems and so requires a large area to exist. Any protections afforded to the monarch butterfly will at the same time umbrella many other species and habitats. An umbrella species is often used as flagship species, which are species, such as the giant panda, the blue whale, the tiger, the mountain gorilla and the monarch butterfly, that capture the public's attention and attract support for conservation measures. Paradoxically, however, conservation bias towards flagship species sometimes threatens other species of chief concern.
Lamarckism
Lamarckism (or Lamarckian inheritance) is the hypothesis that an organism can pass on characteristics that it has acquired through use or disuse during its lifetime to its offspring. It is also known as the inheritance of acquired characteristics or soft inheritance. It is inaccurately named after the French biologist Jean - Baptiste Lamarck (1744 -- 1829), who incorporated the action of soft inheritance into his evolutionary theories as a supplement to his concept of orthogenesis, a drive towards complexity. The theory is cited in textbooks to contrast with Darwinism. This paints a false picture of the history of biology, as Lamarck did not originate the idea of soft inheritance, which was known from the classical era onwards. It was not the primary focus of Lamarck's theory of evolution; further, in On the Origin of Species (1859), Charles Darwin supported the idea of ``use and disuse inheritance '', though rejecting other aspects of Lamarck's theory.
On the Origin of Species
On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the "Beagle" expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.
Willow
Willows, also called sallows, and osiers, form the genus Salix, around 400 species of deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions of the Northern Hemisphere. Most species are known as willow, but some narrow - leaved shrub species are called osier, and some broader - leaved species are referred to as sallow (from Old English sealh, related to the Latin word salix, willow). Some willows (particularly arctic and alpine species) are low - growing or creeping shrubs; for example, the dwarf willow (Salix herbacea) rarely exceeds 6 cm (2.4 in) in height, though it spreads widely across the ground.
Dog
In 1758, the taxonomist Linnaeus published in Systema Naturae a categorization of species which included the Canis species. Canis is a Latin word meaning dog, and the list included the dog-like carnivores: the domestic dog, wolves, foxes and jackals. The dog was classified as Canis familiaris, which means "Dog-family" or the family dog. On the next page he recorded the wolf as Canis lupus, which means "Dog-wolf". In 1978, a review aimed at reducing the number of recognized Canis species proposed that "Canis dingo is now generally regarded as a distinctive feral domestic dog. Canis familiaris is used for domestic dogs, although taxonomically it should probably be synonymous with Canis lupus." In 1982, the first edition of Mammal Species of the World listed Canis familiaris under Canis lupus with the comment: "Probably ancestor of and conspecific with the domestic dog, familiaris. Canis familiaris has page priority over Canis lupus, but both were published simultaneously in Linnaeus (1758), and Canis lupus has been universally used for this species", which avoided classifying the wolf as the family dog. The dog is now listed among the many other Latin-named subspecies of Canis lupus as Canis lupus familiaris.
List of Pokémon
Due to the large number of Pokémon, listing of each species is divided into articles by generation. All 807 Pokémon are organized by their number in the National Pokédex -- an in - game electronic encyclopedia that provides various information on Pokémon. The National Pokédex is subdivided into regional Pokédex series, each revolving around species introduced at the time of their respective generations along with older generations. For example, the Johto Pokédex, Generation II, covers the 100 species introduced in Gold and Silver in addition to the original 151 species. The encyclopedias follow a general ordering: starter Pokémon are listed first, followed by species obtainable early in the respective games, and are concluded with Legendary and Mythical Pokémon. Generation V is a notable exception, as Victini is the first Pokémon in the Unova Pokedex and is also uniquely numbered as number 0.
Bacteria
The ancestors of modern bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. For about 3 billion years, most organisms were microscopic, and bacteria and archaea were the dominant forms of life. Although bacterial fossils exist, such as stromatolites, their lack of distinctive morphology prevents them from being used to examine the history of bacterial evolution, or to date the time of origin of a particular bacterial species. However, gene sequences can be used to reconstruct the bacterial phylogeny, and these studies indicate that bacteria diverged first from the archaeal / eukaryotic lineage. The most recent common ancestor of bacteria and archaea was probably a hyperthermophile that lived about 2.5 billion -- 3.2 billion years ago.

Orectanthe
Orectanthe is a genus of flowering plants, in the family Xyridaceae, first described as a genus in 1958. It is native to the tepui of northern South America (Venezuela, Guyana, and northwestern Brazil). It is closely related to "Abolboda", and both known species were originally classified as members of "Abolboda" before being transferred to "Orectanthe".
Endangered Species Act of 1973
The Endangered Species Conservation Act (P. L. 91-135), passed in December, 1969, amended the original law to provide additional protection to species in danger of "worldwide extinction" by prohibiting their importation and subsequent sale in the United States. It expanded the Lacey Act's ban on interstate commerce to include mammals, reptiles, amphibians, mollusks and crustaceans. Reptiles were added mainly to reduce the rampant poaching of alligators and crocodiles. This law was the first time that invertebrates were included for protection.
Darwinism
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809 -- 1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called Darwinian theory, it originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance after Darwin published On the Origin of Species in 1859, including concepts which predated Darwin's theories. It subsequently referred to the specific concepts of natural selection, the Weismann barrier, or the central dogma of molecular biology. Though the term usually refers strictly to biological evolution, creationists have appropriated it to refer to the origin of life, and it has even been applied to concepts of cosmic evolution, both of which have no connection to Darwin's work. It is therefore considered the belief and acceptance of Darwin's and of his predecessors' work -- in place of other theories, including divine design and extraterrestrial origins.
Alfred Russel Wallace
Alfred Russel Wallace OM FRS (8 January 1823 -- 7 November 1913) was a British naturalist, explorer, geographer, anthropologist, and biologist. He is best known for independently conceiving the theory of evolution through natural selection; his paper on the subject was jointly published with some of Charles Darwin's writings in 1858. This prompted Darwin to publish his own ideas in On the Origin of Species. Wallace did extensive fieldwork, first in the Amazon River basin and then in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia.
1860 Oxford evolution debate
The 1860 Oxford evolution debate took place at the Oxford University Museum in Oxford, England, on 30 June 1860, seven months after the publication of Charles Darwin's "On the Origin of Species". Several prominent British scientists and philosophers participated, including Thomas Henry Huxley, Bishop Samuel Wilberforce, Benjamin Brodie, Joseph Dalton Hooker and Robert FitzRoy.
