Portal:Biology
From Wikipedia, the free encyclopedia
(Redirected from Biology portal)
Welcome to the biology portal. Biology, from the Greek words bios (life) and the suffix -ology, meaning study of, is a branch of science. It is concerned with the characteristics and behaviors of organisms, how species and individuals come into existence, and the interactions they have with each other and with their environment. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. Together, they study life over a wide range of scales.
Blue has been chosen as the colour for this portal to emphasise that life on Earth relies on the unique chemistry of water. A photo of Darlingtonia californica, the cobra lily, was chosen as the portal icon because of this species' dependency on a humid habitat, as well as illustrating both autotrophy (in this case, photosynthesis) and carnivory. Finally, they superficially resemble young shoots, with their tips curved in, symbolising growth, a feature of all life.
Natural selection is the evolutionary process by which favorable traits that are heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common. Natural selection acts on the phenotype, or observable characteristics of an organism, such that individuals with favorable phenotypes are more likely to survive and reproduce than those with less favorable phenotypes. If these phenotypes have a genetic basis, then the genotype associated with the favorable phenotype will increase in frequency in the next generation. Over time, this process can result in adaptations that specialize organisms for particular ecological niches and may eventually result in the emergence of new species.
Natural selection is one of the cornerstones of modern biology. The term was introduced by Charles Darwin in his groundbreaking 1859 book The Origin of Species in which natural selection was described by analogy to artificial selection, a process by which individuals with traits considered desirable by human breeders are systematically favored for reproduction. The concept of natural selection was originally developed in the absence of a theory of inheritance; at the time of Darwin's writing, nothing was known of modern genetics. Although Gregor Mendel, whose work is now considered the foundation of modern genetics, was a contemporary of Darwin's, this work would lie in obscurity until the early 20th century. The union of traditional Darwinian evolution with subsequent discoveries in classical and later molecular genetics is termed the modern evolutionary synthesis. Although other mechanisms of molecular evolution, such as the neutral theory advanced by Motoo Kimura, have been identified as important causes of genetic diversity, natural selection remains the single primary explanation for adaptive evolution.
Alfred Russel Wallace, OM, FRS (January 8, 1823 – November 7, 1913) was a British naturalist, explorer, geographer, anthropologist and biologist. He did extensive field work first in the Amazon River basin, and then in the Malay Archipelago, where he identified the Wallace line dividing the fauna of Australia from that of Asia.
He is best known for independently proposing a theory of natural selection which prompted Charles Darwin to publish his own more developed and researched theory sooner than he had intended. He was also one of the leading evolutionary thinkers of the 19th century who made a number of other contributions to the development of evolutionary theory, including the concept of warning colouration in animals. Wallace was also considered the 19th century’s leading expert on the geographical distribution of animal species and is sometimes called the "father of biogeography".
Wallace was strongly attracted to radical ideas in politics, religion and science. His advocacy of spiritualism and his belief in a non material origin for the higher mental faculties of humans strained his relationship with the scientific establishment, especially with other early proponents of evolution. He was a strong critic of what he considered to be an unjust social and economic system in 19th-century Britain. He was one of the first prominent scientists to raise concerns over the environmental impact of human activity.
