Evolution is change in the heritable characteristics of biologicalpopulations over successive generations. Evolutionary processes give rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. Repeated formation of new species speciation, change within species anagenesis, and loss of species extinction throughout the evolutionary history of life on Earth are demonstrated by shared sets of morphological and biochemical traits, including shared DNA sequences. These shared traits are more similar among species that share a more recent common ancestor, and can be used to reconstruct a biological tree of life based on evolutionary relationships phylogenetics, using both existing species and fossils. The fossil record includes a progression from early biogenicgraphite,5 to microbial mat fossils,678 to fossilised multicellular organisms. Existing patterns of biodiversity have been shaped both by speciation and by extinction. In the mid 1. Charles Darwin formulated the scientific theory of evolution by natural selection, published in his book On the Origin of Species 1. Evolution by natural selection is a process demonstrated by the observation that more offspring are produced than can possibly survive, along with three facts about populations 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. This teleonomy is the quality whereby the process of natural selection creates and preserves traits that are seemingly fitted for the functional roles they perform. The processes by which the changes occur, from one generation to another, are called evolutionary processes or mechanisms. The recent Google Memo on diversity, and the immediate firing of its author, James Damore, have raised a number of questions relevant to the mission of Heterodox Academy. The four most widely recognised evolutionary processes are natural selection including sexual selection, genetic drift, mutation and gene migration due to genetic admixture. Natural selection and genetic drift sort variation mutation and gene migration create variation. Consequences of selection can include meiotic drive1. In the early 2. 0th century the modern evolutionary synthesis integrated classical genetics with Darwins theory of evolution by natural selection through the discipline of population genetics. The importance of natural selection as a cause of evolution was accepted into other branches of biology. Moreover, previously held notions about evolution, such as orthogenesis, evolutionism, and other beliefs about innate progress within the largest scale trends in evolution, became obsolete. The Studies in Language Testing SiLT series of academic volumes address new developments in language testing and assessment. Find out more.

Scientists continue to study various aspects of evolutionary biology by forming and testing hypotheses, constructing mathematical models of theoretical biology and biological theories, using observational data, and performing experiments in both the field and the laboratory. All life on Earth shares a common ancestor known as the last universal common ancestor LUCA,1. This should not be assumed to be the first living organism on Earth a study in 2. Western Australia. In July 2. 01. 6, scientists reported identifying a set of 3. LUCA of all organisms living on Earth. More than 9. 9 percent of all species that ever lived on Earth are estimated to be extinct. Estimates of Earths current species range from 1. More recently, in May 2. Earth currently with only one thousandth of one percent described. In terms of practical application, an understanding of evolution has been instrumental to developments in numerous scientific and industrial fields, including agriculture, human and veterinary medicine, and the life sciences in general. Discoveries in evolutionary biology have made a significant impact not just in the traditional branches of biology but also in other academic disciplines, including biological anthropology, and evolutionary psychology. Evolutionary computation, a sub field of artificial intelligence, involves the application of Darwinian principles to problems in computer science. History of evolutionary thought. Classical times. The proposal that one type of organism could descend from another type goes back to some of the first pre Socratic Greek philosophers, such as Anaximander and Empedocles. Such proposals survived into Roman times. The poet and philosopher. Lucretius followed Empedocles in his masterwork De rerum natura On the Nature of Things. Medieval. In contrast to these materialistic views, Aristotelianism considered all natural things as actualisations of fixed natural possibilities, known as forms. This was part of a medieval teleological understanding of nature in which all things have an intended role to play in a divinecosmic order. Variations of this idea became the standard understanding of the Middle Ages and were integrated into Christian learning, but Aristotle did not demand that real types of organisms always correspond one for one with exact metaphysical forms and specifically gave examples of how new types of living things could come to be. Pre Darwinian. In the 1. Aristotelian approach. It sought explanations of natural phenomena in terms of physical laws that were the same for all visible things and that did not require the existence of any fixed natural categories or divine cosmic order. However, this new approach was slow to take root in the biological sciences, the last bastion of the concept of fixed natural types. John Ray applied one of the previously more general terms for fixed natural types, species, to plant and animal types, but he strictly identified each type of living thing as a species and proposed that each species could be defined by the features that perpetuated themselves generation after generation. The biological classification introduced by Carl Linnaeus in 1. Other naturalists of this time speculated on the evolutionary change of species over time according to natural laws. In 1. 75. 1, Pierre Louis Maupertuis wrote of natural modifications occurring during reproduction and accumulating over many generations to produce new species. Georges Louis Leclerc, Comte de Buffon suggested that species could degenerate into different organisms, and Erasmus Darwin proposed that all warm blooded animals could have descended from a single microorganism or filament. The first full fledged evolutionary scheme was Jean Baptiste Lamarcks transmutation theory of 1. The latter process was later called Lamarckism. These ideas were condemned by established naturalists as speculation lacking empirical support. In particular, Georges Cuvier insisted that species were unrelated and fixed, their similarities reflecting divine design for functional needs. In the meantime, Rays ideas of benevolent design had been developed by William Paley into the Natural Theology or Evidences of the Existence and Attributes of the Deity 1. Charles Darwin. 5. Darwinian revolution. The crucial break from the concept of constant typological classes or types in biology came with the theory of evolution through natural selection, which was formulated by Charles Darwin in terms of variable populations. Partly influenced by An Essay on the Principle of Population 1. Thomas Robert Malthus, Darwin noted that population growth would lead to a struggle for existence in which favorable variations prevailed as others perished. In each generation, many offspring fail to survive to an age of reproduction because of limited resources.
