The Genetics of Kinds - Ravens, Owls, and Doves

چکیده
Cytochrome b (cytb), one of the most widely used and accepted genes for phylogenetic studies, was employed to evaluate the genetic diversity, from a creationist standpoint, within and between species of ravens, species of owls, and species of doves. These species were chosen since they are known to have existed shortly after the flood, some documented within 400 years of the flood. It was found that within these species, cytb varied by approximately 1 percent or less and between species, the cytb varied between 4.1% and 25.3%; for example, the Barn Owl and the Spotted Eagle Owl differed in cytb by 25.3%. This variation is more than the cytb variance between a mouse and a pig, or a horse and a cow and nearly as much as the variation between a cow and a zebra fish (29%). This study concludes that all the subject species of ravens, species of owls, and species of doves were on the Ark. The alternative theory, which is now accepted by some creation scientists, is that speciation occurred after disembarkation from the Ark; this theory requires accepting full blown evolutionary processes (speciation through natural selection etc.) functioning at speeds on the order of 60,000 times that of published evolutionary literature.

Introgression and dispersal among spotted owl (Strix occidentalis) subspecies
Population genetics plays an increasingly important role in the conservation and management of declining species, particularly for defining taxonomic units. Subspecies are recognized by several conservation organizations and countries and receive legal protection under the US Endangered Species Act (ESA). Two subspecies of spotted owls, northern (Strix occidentalis caurina) and Mexican (S. o. l...
متن کاملGenetic characterization of Toxoplasma gondii isolates from eared doves (Zenaida auriculata) in Brazil Caracterização genética de isolados de Toxoplasma gondii de pombos (Zenaida auriculata) no Brasil
Eared doves (Zenaida auriculata), which are common in urban, rural and wild areas in many regions of Brazil, are frequently prey for domestic cats. Therefore Toxoplasma gondii isolates obtained from doves may reflect greater environmental diversity than those from other hosts. The aim of the present study was to evaluate T. gondii seroprevalence, isolate and genotype strains from Z. auriculata....
متن کاملOwls May Use Faeces and Prey Feathers to Signal Current Reproduction
BACKGROUND Many animals communicate by marking focal elements of their home range with different kinds of materials. Visual signaling has been demonstrated to play a previously unrecognized role in the intraspecific communication of eagle owls (Bubo bubo), in both territorial and parent-offspring contexts. Visual signals may play a role in a variety of circumstances in this crepuscular and noct...

In the ongoing debate over drug policy, the strategy of harm reduction, or harm minimization, has often been surrounded by ideological argumentation. This strategy, essentially a health and social services policy, has been portrayed as camouflaged legalization by those who prefer the policy of drug control through repression, or considered unacceptable because it permits a social group engaged ...
متن کاملEvidence for Recent Population Bottlenecks in Northern Spotted Owls (<i>Strix occidentalis caurina</i>)
The northern spotted owl (Strix occidentalis caurina) is one of the most controversial threatened subspecies ever listed under the US Endangered Species Act. Despite protection of its remaining forest habitat, recent field studies show continued declines of northern spotted owls. One potential threat to northern spotted owls which has not yet been shown is loss of genetic variation from populat...
