VestigialityVestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to positive selection pressures when it loses its value in a changing environment.
Evolutionary creationEvolutionary creation, also presented as Evolutionary creationism, is the religious belief that God created the earth using processes of evolution. The concept is similar to theistic evolution and accepts modern science, but there are theological differences. Its supporters, who tend to be conservative evangelical Christians, hold that God continues to be actively involved in evolution, to a greater extent than theistic evolutionists believe this. There is diversity among evolutionary creationists in explaining how these two concepts fit together.
Fine-tuned universeThe characterization of the universe as finely tuned suggests that the occurrence of life in the universe is very sensitive to the values of certain fundamental physical constants and that other values different from the observed ones are, for some reason, improbable. If the values of any of certain free parameters in contemporary physical theories had differed only slightly from those observed, the evolution of the universe would have proceeded very differently and life as it is understood may not have been possible.
Answers in GenesisAnswers in Genesis (AiG) is an American fundamentalist Christian apologetics parachurch organization. It advocates Young Earth creationism on the basis of its literal, historical-grammatical interpretation of the Book of Genesis and the Bible as a whole. Out of belief in biblical inerrancy, it rejects the results of scientific investigations that contradict their view of the Genesis creation narrative and instead supports pseudoscientific creation science.
Historical criticismHistorical criticism, also known as the historical-critical method or higher criticism, is a branch of criticism that investigates the origins of ancient texts in order to understand "the world behind the text". While often discussed in terms of Jewish and Christian writings from ancient times, historical criticism has also been applied to other religious and secular writings from various parts of the world and periods of history.
Islamic views on evolutionIslamic views on evolution are diverse, ranging from theistic evolution to Old Earth creationism. Some Muslims around the world believe "humans and other living things have evolved over time", yet some others believe they have "always existed in present form". Some Muslims believe that the processes of life on Earth started from one single point of species with a mixture of water and a viscous clay-like substance. Muslim thinkers have proposed and accepted elements of the theory of evolution, some holding the belief of the supremacy of God in the process.
Alternatives to Darwinian evolutionAlternatives to Darwinian evolution have been proposed by scholars investigating biology to explain signs of evolution and the relatedness of different groups of living things. The alternatives in question do not deny that evolutionary changes over time are the origin of the diversity of life, nor that the organisms alive today share a common ancestor from the distant past (or ancestors, in some proposals); rather, they propose alternative mechanisms of evolutionary change over time, arguing against mutations acted on by natural selection as the most important driver of evolutionary change.
