It then became generally understood that classifications ought to reflect the phylogeny of organisms, their descent by evolution.

The theory of recapitulation, also called the biogenetic law or embryological parallelism — and often expressed as " ontogeny recapitulates phylogeny "— is a biological hypothesis that in developing from embryo to adult, animals go through stages resembling or representing successive stages in the evolution of their remote ancestors.

The result of phylogenetic studies is a hypothesis about the evolutionary history of taxonomic groups: their phylogeny.

In biology, phenetics (), also known as taximetrics, is an attempt to classify organisms based on overall similarity, usually in morphology or other observable traits, regardless of their phylogeny or evolutionary relation.

However, certain phenetic methods, such as neighbor-joining, have found their way into cladistics, as a reasonable approximation of phylogeny when more advanced methods ( such as Bayesian inference ) are too computationally expensive.

It was subsequently realized that Edentata was polyphyletic — that it contained not just an exclusive group of families and was subsequently split up to reflect their true phylogeny.

Most scientists working with vertebrates use a classification based purely on phylogeny, organized by their known evolutionary history and sometimes disregarding the conventional interpretations of their anatomy and physiology.

A molecular phylogeny based on rDNA analysis dating from 2005 suggests that salamanders and caecilians are more closely related to each other than they are to frogs and that the divergence of the three groups took place in the Paleozoic or early Mesozoic before the breakup of the supercontinent Pangaea and soon after their divergence from the lobe-finned fish.

Chaetognatha appears close to the base of the protostome tree in most studies of their molecular phylogeny.

The classification of euglenids is still variable, as groups are being revised to conform with their molecular phylogeny.

The precise limits between Arctium and Cousinia are hard to define ; there is an exact correlation between their molecular phylogeny.

Current taxonomic changes as of 2009 and 2011, based upon molecular phylogeny ( see below ), have elevated the subfamilies which were previously in the family Turridae to the status of families in their own right, leaving the family Conidae once again containing the species which were traditionally placed in that family.

In 2009 John K. Tucker and Manuel J. Tenorio proposed a classification system for the cone shells and their allies ( which resorb their inner walls during growth ) was based upon a cladistical analysis of anatomical characters including the radular tooth, the morphology ( i. e., shell characters ), as well as an analysis of prior molecular phylogeny studies, all of which were used to construct phylogenetic trees.

Along with his analysis of pheasant phylogeny and his studies of life in the Galápagos islands, Beebe regarded one of his most important contributions to the field of evolutionary biology to be his hypothesis that the ancestors of birds passed through what he referred to as a “ Tetrapteryx stage ”, with wings on both their front and hind limbs.

The phylogeny of the Acari is still disputed and several taxonomic schemes have been proposed for their classification.

They are, however, quite distinctly united by their anatomy, and the family's phylogeny as well as the most ancient fossils of this order suggest that the original lampriform was indeed rather " opah-shaped ".

Despite the almost identical and highly apomorphic nuptial plumage of their males, which continues to puzzle scientists ( see the Green-winged Teal page for a discussion of the species ' phylogeny ), they seem well distinct species, as indicated by a wealth of behavioural, morphological and molecular data.

In their suggested phylogeny, the Hoatzin was a basal member of the Metaves, a proposed clade that would include many other historically problematic bird families, such as flamingos, grebes, tropicbirds, sandgrouse and mesites.

Because bracket fungi are defined by their growth form rather than phylogeny, the group contains members of multiple clades.

Morphological phylogeny of cobweb spiders and their relatives ( Araneae, Araneoidea, Theridiidae ).

While species are generally well circumscribed, their attribution to subfamilies and genera is sometimes equivocal, and there is minimal information about phylogeny and relationships of the species, not least because most work has been based on adult morphology ( Barucca et al., 2004 ).

" The first well-known version of anarcho-capitalism was formulated by Austrian School economist and libertarian Murray Rothbard in the mid-twentieth century, synthesizing elements from the Austrian School of economics, classical liberalism, and nineteenth century American individualist anarchists Lysander Spooner and Benjamin Tucker ( rejecting their labor theory of value and the normative implications they derived from it ).

Soal discovered, to his surprise, that four of his former participants, Randolph Tucker Pendleton IV, Amanda Bailey, Ling Dao and Rachel Brown, evidenced displacement: i. e., their responses significantly corresponded to targets for trials one removed from which they were assigned.

A major schism occurred later in the 19th century when Tucker and some others abandoned their traditional support of natural rights-as espoused by Lysander Spooner-and converted to an " egoism " modeled upon Stirner's philosophy.

Nicholas Tucker described the early Harry Potter books as looking back to Victorian and Edwardian children's stories: Hogwarts was an old-style boarding school in which the teachers addressed pupils formally by their surnames and were most concerned with the reputations of the houses with which they were associated ; characters ' personalities were plainly shown by their appearances, starting with the Dursleys ; evil or malicious characters were to be crushed rather than reformed, including Filch's cat Mrs Norris ; and the hero, a mistreated orphan who found his true place in life, was charismatic and good at sports, but considerate and protective towards the weak.

Having a heavy interest in the race cars and their designers, Tucker met Harry Miller, maker of more Indianapolis 500-winning engines than any other during this period.

The small community named after their property is also home to folk of various income levels, ranging from the well-to-do Baldwin sisters, two elderly spinsters who distill moonshine that they call " Papa's recipe "; Ike Godsey, postmaster and owner of the general store with his somewhat snobbish wife Corabeth ( a Walton cousin ); a black couple, Verdie and Harley Foster ; Maude, a sassy octogenarian artist who paints on wood ; Flossie Brimmer, a friendly though somewhat gossipy widow who runs a nearby boarding house ; and Yancy Tucker, a good-hearted handyman with big plans but little motivation.

Benjamin Tucker writes, "... the patent monopoly ... consists in protecting inventors ... against competition for a period long enough to extort from the people a reward enormously in excess of the labor measure of their services, in other words, in giving certain people a right of property for a term of years in laws and facts of Nature, and the power to exact tribute from others for the use of this natural wealth, which should be open to all.

Indeed, as already noted, the Court proceeded on the assumption that the executives involved in the dealings between Du Pont and General Motors acted `` honorably and fairly '' and exercised their business judgment only to serve what they deemed the best interests of their own companies.

Erikson has noted that, unless this trust developed early, the time ambivalence experienced, in varying degree and temporarily, by all adolescents ( as a result of their remembering the more immediate gratification of wants during childhood, while not yet having fully accepted the long-range planning required by adulthood ) may develop into a more permanent sense of time diffusion.
