	Encyclopedia: Catagenesis (biology)
		Catagenesis is an archaic term from evolutionary biology referring to evolutionary directions that were considered "retrogressive." It was a term used in contrast to anagenesis, which in present usage denotes the evolution of a single population into a new form without branching lines of descent.
		Ecological genetics is the study of genetics (itself a field of biology) from an ecological perspective.
		Evolutionary developmental biology (evolution of development or informally, evo-devo) is a field of biology that compares the developmental processes of different animals in an attempt to determine the ancestral relationship between organisms and how developmental processes evolved.

	Evolution
		In biology, evolution is the process by which populations of organisms acquire and pass on novel traits from generation to generation, affecting the overall makeup of the population and even leading to the emergence of new species.
		In biology, the theory of universal common descent proposes that all organisms on Earth are descended from a common ancestor or ancestral gene pool (which is called having "common descent").
		Evolutionary developmental biology is an emergent subfield of evolutionary biology that looks at genes of related and unrelated organisms.

		Evolutionary developmental biology (often referred to as 'evo-devo' or evolution of development) is a field of biology that compares the developmental processes of different animals in an attempt to determine the ancestral relationship between organisms and how developmental processes evolved.
		One of the more surprising and perhaps, counter-intuitive, results of such research in evolutionary developmental biology done in this period, is that both the diversity of body plans and morphology in organisms across many phyla is not necessarily reflected in similar diversity at the level of the genetic sequences controlling development.
		The discovery of the homeotic Hox gene family in vertebrates in the 1980s, allowed researchers in developmental biology to empirically assess the relative roles of the above two factors, with respect to their importance in the evolution of morphological diversity.

		Catagenesis is a term used in petroleum geology to describe the cracking process which results in the conversion of organic kerogens into hydrocarbons.
		It is generally held that the dependence on pressure is negligible, such that the process of catagenesis can be given as a first-order differential equation:
		The term Catagenesis is also used in biology, where it refers to retrogressive evolution.

		In this sense, "theory" and "fact" do not stand in opposition, but rather exist in a reciprocal relationship — for example, it is a "fact" that an apple dropped on earth will fall towards the center of the planet in a straight line, and the "theory" which explains it is the current theory of gravitation.
		Currently, the modern synthesis is the most powerful theory explaining variation and speciation, and within the science of biology it has completely replaced earlier accepted explanations for the origin of species, including Lamarckism and the creationism of the 18th and 19th centuries.

	Definition of Phylogenetics - Biocrawler (Site not responding. Last check: 2007-09-14)
		Phylogeny (or phylogenesis), is the origin and evolution of a set of organisms, usually of a species.
		The early version of this hypothesis has since been rejected as being oversimplified and misleading.
		However, modern biology recognizes numerous connections between ontogeny and phylogeny, explains them using evolutionary theory, and views them as supporting evidence for that theory.

	Charles Darwin (Site not responding. Last check: 2007-09-14)
		His observations of biology led him to study transmutation of species and develop his theory of natural selection in 1838.
		Despite this hope, the "Lady Hope Story" claiming his sickbed conversion was published in 1915 and has since been much propagated by some Christian groups to the extent of becoming an urban legend, though the claims were refuted by Darwin's children.
		His work established that "evolution" had occurred: not necessarily that it was by natural or sexual selection (this particular recognition would not become fully standard until the rediscovery of Gregor Mendel's work in the early 20th century and the creation of the modern synthesis).

		The roots of this new semiotic paradigm are no longer in linguistics, but in biology, ethology, cosmology, and philosophy.
		This mode of genesis is related to two more general evolutionary principles, anagesis, the complexification of matter, and catagenesis, the decomplexification of matter.
		The preliminary climax of the evolution of Koch’s semiotics from linguistics towards pansemiotics is his semiotics of Everything under the Sun (Koch 1991) and, more recently, his Philosophy of Everything (see http://www.walterkoch.de).

		During the 1980s and 1990s more comparative molecular sequence data between different kinds of organisms was amassed and detailed understanding of the molecular basis of the developmental mechanisms which are encoded by those genes has become clearer.
		Evolutionary developmental biology has arisen in response to these data.
		Several biologists, including Sean B. Carroll of the University of Wisconsin suggest that "changes in the cis-regulatory systems of genes" are more significant than "changes in gene number or protein function" (Carroll 2000).
