A recently observed example has as protagonists M.xanthus (predator) and E.coli (prey) in which a parallel evolution of both species can be observed through genomic and phenotypic modifications, producing in future generations a better adaptation of one of the species that is counteracted by the evolution of the other, thus generating an arms ...
Universal Darwinism, also known as generalized Darwinism, universal selection theory, [1] or Darwinian metaphysics, [2] [3] [4] is a variety of approaches that extend the theory of Darwinism beyond its original domain of biological evolution on Earth. Universal Darwinism aims to formulate a generalized version of the mechanisms of variation ...
Universal evolution is a theory of evolution formulated by Pierre Teilhard de Chardin and Julian Huxley that describes the gradual development of the Universe from subatomic particles to human society, considered by Teilhard as the last stage.
Darwinism subsequently referred to the specific concepts of natural selection, the Weismann barrier, or the central dogma of molecular biology. [2] Though the term usually refers strictly to biological evolution, creationists have appropriated it to refer to the origin of life or to cosmic evolution, that are distinct to biological evolution, [3] and therefore consider it to be the belief and ...
Two useful introductions to the fundamental theory underlying the unit of selection issue and debate, which also present examples of multi-level selection from the entire range of the biological hierarchy (typically with entities at level N-1 competing for increased representation, i.e., higher frequency, at the immediately higher level N, e.g., organisms in populations or cell lineages in ...
Given the right circumstances, and enough time, evolution leads to the emergence of new species. Scientists have struggled to find a precise and all-inclusive definition of species. Ernst Mayr defined a species as a population or group of populations whose members have the potential to interbreed naturally with one another to produce viable ...
In an influential paper, Wiens and Donoghue [3] laid out how phylogenetic niche conservatism might help explain the latitudinal diversity gradient.While support for the hypothesis that niche conservatism drives latitudinally structured variation in species richness has been found in some clades, [11] overall, phylogenetic niche conservatism has not received strong support as the underlying ...
Conservation biology as a discipline reaches beyond biology, into subjects such as philosophy, law, economics, humanities, arts, anthropology, and education. [5] [6] Within biology, conservation genetics and evolution are immense fields unto themselves, but these disciplines are of prime importance to the practice and profession of conservation ...
