Although several versions of many-worlds have been proposed since Hugh Everett's original work, they all contain one key idea: the equations of physics that model the time evolution of systems without embedded observers are sufficient for modelling systems which do contain observers ; in particular there is no observation-triggered wave function collapse which the Copenhagen interpretation proposes.

Although it appears that globular clusters contain some of the first stars to be produced in the galaxy, their origins and their role in galactic evolution are still unclear.

Although they accept that some complex systems and organs can be explained by evolution, they claim that organs and biological features which are irreducibly complex cannot be explained by current models, and that an intelligent designer must have created life or guided its evolution.

Although Behe acknowledged that the evolution of the larger anatomical features of the eye have been well-explained, he claimed that the complexity of the minute biochemical reactions required at a molecular level for light sensitivity still defies explanation.

Although social scientists such as Max Weber sought to understand and explain religion in terms of a cultural attribute, Richard Dawkins called for a re-analysis of religion in terms of the evolution of self-replicating ideas apart from any resulting biological advantages they might bestow.

Although a complete theory of evolution also requires an account of how genetic variation arises in the first place ( such as by mutation and sexual reproduction ) and includes other evolutionary mechanisms ( such as genetic drift and gene flow ), natural selection appears to be the most important mechanism for creating complex adaptations in nature.

Although histones are remarkably conserved throughout evolution, several variant forms have been identified.

Although in some cases actinofibrils ( internal structural fibres ) in the wing membrane have been mistaken for pycnofibres or true hair, some fossils such as those of Sordes pilosus ( which translates as " hairy demon ") and Jeholopterus ninchengensis do show the unmistakable imprints of pycnofibres on the head and body, not unlike modern-day bats, another example of convergent evolution.

Although Simpson allowed for the existence of stasis in what he called the bradytelic mode, Simpson considered it ( along with rapid evolution ) to be insignificant in the larger scope of evolution.

Although the Super Bowl had grown into America's biggest one-day sporting event by this point, many believe the 13th edition began the game's evolution to unofficial national holiday.

Although these alleles have differing frequencies across African, European and Asian populations, there is no evidence of positive selection for them and they do not appear to be associated with the evolution of lighter skin in Eurasian populations.

Although Barricelli, in work he reported in 1963, had simulated the evolution of ability to play a simple game, artificial evolution became a widely recognized optimization method as a result of the work of Ingo Rechenberg and Hans-Paul Schwefel in the 1960s and early 1970s – Rechenberg's group was able to solve complex engineering problems through evolution strategies.

Although quantum evolution may happen at any taxonomic level ( 1953, 389 ), it plays a much larger role in " the origin taxonomic units of relatively high rank, such as families, orders, and classes.

Although often described as an evolution of Marxism / Leninism, Maoism is defined more by its theoretical and ideological departures from orthodox Marxism or Leninism than by its similarities to the Western versions of modern socialism.

Although most of these multigenerational epigenetic traits are gradually lost over several generations, the possibility remains that multigenerational epigenetics could be another aspect to evolution and adaptation.

Although he is perfectly willing to cooperate with Scotland Yard, Holmes has nothing but contempt for the intelligence and mentality of the police.

Although Patchen has given previous evidence of an interest in jazz, the musical group that he works with, the Chamber Jazz Sextet, is often ignored by jazz critics.

Although today's trucks are as fast as passenger cars, a truck driver has to be a sensible person and guard against hogging the road.

Although the matter has not been unequivocally demonstrated, the available data show that micelles in themselves do not contribute significantly to the detergency process.

Although a somewhat technical subject, it has important political implications as the above discussion of the voting system indicated.

Although the pause in the advance of general business activity this year has thus far been quite modest, it is hard to escape the conclusion that the softening process will continue into the first quarter of 1961 and possibly somewhat longer.

Although refrigeration has served to extend the storage life of these products, substantially increased consumption might be possible if areas remote from the seacoast could be served adequately.

Although science has given us more effective materials, preparations from anise, castorbean, colchicum, nux vomica, mustard, fennel, and stramonium are familiar to many for the relief of human ailments.

Although progress has been made in America's system of libraries it still falls short of what is required if we are to maintain the standards that are needed for an informed America.

Although I have emphasized the barriers which an aroused nationalism has raised against relations between Christians and non-Christians in Asia, the fact is that this development has also widened the gulf between certain Afro-Asian religions themselves.

Although the axiom of countable choice in particular is commonly used in constructive mathematics, its use has also been questioned.

Although argon is a noble gas, it has been found to have the capability of forming some compounds.

Although the Indian and Greek concepts of the atom were based purely on philosophy, modern science has retained the name coined by Democritus.

Although panic attacks are not experienced by every person who has anxiety, they are a common symptom.

Although a cease-fire has held since 1994, the conflict with Azerbaijan over Nagorno-Karabakh has not been resolved.

Although MacDougall's results varied considerably from " 21 grams ", for some people this figure has become synonymous with the measure of a soul's mass.

Although, as of 2009, none of the extrasolar planets detected by ground-based astrometry has been verified in subsequent studies, astrometry is expected to be more accurate in space missions that are not affected by the distorting effects of the Earth's atmosphere.

Although hydrogen-like orbitals are still used as pedagogical tools, the advent of computers has made STOs preferable for atoms and diatomic molecules since combinations of STOs can replace the nodes in hydrogen-like atomic orbital.

Although the sign still exists, the " of " has now been replaced by the URL of their website.

Although the Caiman has not been studied in-depth, scientists have learned that their mating cycles ( previously thought to be spontaneous or year-round ) are linked to the rainfall cycles and the river levels, which increases chances of survival for their offspring.
