Alfred Wallace
Alfred Russel Wallace (8 January 1823 – 7 November 1913) was an English naturalist, explorer, geographer, anthropologist, biologist and illustrator. He independently conceived the theory of evolution through natural selection; his 1858 paper on the subject was published that year On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection, alongside extracts from Charles Darwin's earlier writings on the topic. It spurred Darwin to set aside the Natural Selection (manuscript), "big species book" he was drafting and to quickly write an Abstract (summary), abstract of it, which was published in 1859 as ''On the Origin of Species''. Wallace did extensive fieldwork, starting in the Amazon River basin. He then did fieldwork 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 ani ...

Order Of Merit
The Order of Merit () is an order of merit for the Commonwealth realms, recognising distinguished service in the armed forces, science, art, literature, or the promotion of culture. Established in 1902 by Edward VII, admission into the order remains the personal gift of its Sovereign—currently Edward VII's great-great-grandson Charles III—and is restricted to a maximum of 24 living recipients from the Commonwealth realms, plus honorary members. While all members are awarded the right to use the post-nominal letters ''OM'' and wear the badge of the order, the Order of Merit's precedence among other honours differs between countries. History In around 1773, George III considered establishing an order of knighthood to be called the "Order of Minerva" with membership restricted to 24 distinguished artists and authors. Knights would be entitled to the post-nominal letters ''KM'', and would wear a silver nine-pointed breast star with the image of Minerva at its centre, along wi ...

Australasian Realm
The Australasian realm is one of eight biogeographic realms that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccas (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas. The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the ...

Malay Archipelago
The Malay Archipelago is the archipelago between Mainland Southeast Asia and Australia, and is also called Insulindia or the Indo-Australian Archipelago. The name was taken from the 19th-century European concept of a Malay race, later based on the distribution of Austronesian languages. It has also been called the " Malay world," " Nusantara", "East Indies" over time. The name is controversial in Indonesia due to its ethnic connotations and colonial undertones, which can overshadow the country's diverse cultures. Situated between the Indian and Pacific oceans, the archipelago of over 25,000 islands and islets is the largest archipelago by area and fifth by number of islands in the world. It includes Brunei, East Timor, Indonesia, Malaysia (specifically East Malaysia), Papua New Guinea, and the Philippines.''Encyclopædia Britannica''. 2006. Chicago: Encyclopædia Britannica, Inc. The term is largely synonymous with Maritime Southeast Asia. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazon River Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, it is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . The Amazon River Basin occupies the entire central and eastern area of South America, lying to the east of the Andes mountain range and extending from the Guyana Plateau in the north to the Brazilian Plateau in the sou ...

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'')The book's full original title was ''On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life''. In the 1872 sixth edition, "On" was omitted, so the full title is ''The origin of species by means of natural selection, or the preservation of favoured races in the struggle for life.'' This edition is usually known as ''The Origin of Species.'' The 6th is Darwin's final edition; there were minor modifications in the text of certain subsequent issues. See Freeman, R. B. In Van Wyhe, John, ed. ''Darwin Online: On the Origin of Species'', 2002. is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology. It was published on 24 November 1859. Darwin's book introduced the scientific theory that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abstract (summary)
An abstract is a brief summary of a research article, thesis, review, conference proceeding, or any in-depth analysis of a particular subject and is often used to help the reader quickly ascertain the paper's purpose. When used, an abstract always appears at the beginning of a manuscript or typescript, acting as the point-of-entry for any given academic paper or patent application. Abstracting and indexing services for various academic disciplines are aimed at compiling a body of literature for that particular subject. The terms ''précis'' or ''synopsis'' are used in some publications to refer to the same thing that other publications might call an "abstract". In management reports, an '' executive summary'' usually contains more information (and often more sensitive information) than the abstract does. Purpose and limitations Academic literature uses the abstract to succinctly communicate complex research. An abstract may act as a stand-alone entity instead of a full paper. ...

Natural Selection (manuscript)
''Natural Selection'' is the manuscript in which Charles Darwin drafted his planned species book to publish his theory of natural selection. He had noted his concepts in an 1842 Pencil Sketch and an 1844 Essay. In September 1854 he "began sorting notes for species Theory" in preparation for publication, and in May 1856 began writing his ''Natural Selection'' "big book". He was on track to publish sometime between 1859 and 1861, but was interrupted by Wallace sending him a similar concept in 1858, so their essays were read together as papers " On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection". Darwin then wrote an abstract, titled '' On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life'', which he published in 1859. The first two chapters were published in 1868 as ''The Variation of Animals and Plants Under Domestication ''The Variation ...

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] |
On The Tendency Of Species To Form Varieties; And On The Perpetuation Of Varieties And Species By Natural Means Of Selection
"On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection" is the title of a journal article, comprising and resulting from the joint presentation of two scientific papers to the Linnean Society of London on 1 July 1858: ''On The Tendency of Varieties to Depart Indefinitely from the Original Type'' by Alfred Russel Wallace and an ''Extract from an unpublished Work on Species'' from Charles Darwin's ''Essay'' of 1844. The article also includes an ''Abstract of a Letter'' from Darwin to Asa Gray, and an introductory letter by Joseph Dalton Hooker and Charles Lyell. The article was the first announcement of the Darwin–Wallace theory of evolution by natural selection; and appeared in print on 20 August 1858. The presentation of the papers spurred Darwin to write a condensed "abstract" of his "big book", ''Natural Selection''. This was published in November 1859 as '' On the Origin of Species''.

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 ...

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual Cell (biology), cell, a multicellular organism, or a Community (ecology), community of Biological interaction, interacting populations. They usually specialize in a particular Outline of biology#Subdisciplines, branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypothesis, hypotheses. Their discoveries may have Applied science#Applied research, applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans.
