Natural selection tends to work toward genetic unity;the genotypes that are most fit produce the mostoffspring and increase the frequency of adaptive allelesin the population. Yet there remains a great deal ofvariability within the populations of species. Describethe factors that contribute to this genetic variability. Provide the link of references
Match the description with the correct term.A. the idea that inherent variation in a population allows for certain traits to be selected and carried on to future generations of the population experiencing an environmental pressureB.organisms that do not have a common ancestry but develop body parts that perform the same functionC. a model suggesting the gradual change of a species to form distinct speciesD. the idea that all living things on Earth share a common ancestorE. a common ancestor adapts and results in various speciesF. two populations become reproductively isolated (can no longer reproduce successfully)1.speciation 2. adaptive radiation 3. analogous structures 4.theory of evolution 5. gradualism 6. theory of natural selection
Consider the speciation event via which your species O. virginianus White tail deer split from species b O. hemionus Mule Deer (the more closely related species). Taking into account the basic biology of these organisms, briefly describe how each of the four evolutionary forces might have acted in producing that speciation event: genetic drift, gene flow, natural selection and nutation) .Genetic drift .Gene Flow .Nautual selection . Mutation
The difference between sympatric and parapatric speciation is ___. a. parapatric speciation occurs only in worms b. sympatric speciation requires a barrier to gene flow c. the extent of overlap in range d. reproductive isolation does not occur
Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which females could identify and choose a partner from her own species. After some time, pollution made the lake so cloudy it was hard for females to distinguish colors. What might take place in this situation?
Consider two species that diverged whilegeographically separated but resumed contactbefore reproduction isolation was complete. Predictwhat would happen over time if two species matedindiscriminately and a. hybrid offspring survived and reproducedmore poorly than offspring from intraspecificmating or b. hybrid offspring survived and reproduced aswell as offspring from intraspecific mating.Provide an example for each to illustrate yourpoint.
Natural history museums house collections of many kinds ofanimals. These collections contribute to our understanding ofevolution. Most museums still participate in limited collecting,concentrating on particular groups or organisms that will provide aparticular insight into evolution. A bird that was suspected of beinga rare hybrid recently appeared in Missouri, so it was collected forstudy at a nationally recognized museum. Some members of thelocal bird-watching community were upset. a)Do you think that collecting birds such as this suspected hybrid is scientifically justified? Why?
The principle of parsimony a. helps evolutionary biologists distinguish among competing phylogenetic hypotheses. b. does not require that the polarity of traits be determined. c. is a way to avoid having to use outgroups in a phylogenetic analysis. d. cannot be applied to molecular traits.
Indicate the order in which the following steps would take place to result in Allopatric Speciation [enter 1 for the first step, 2 for the second, etc; write only the number -- no words, no spaces] The two groups develop reproductive isolating mechanisms so that they no longer interbreed. Interbreeding populations connected via gene flow occur across a range. The two separate groups adapt to their new environments. Some sort of physical barrier develops to split the once contiguous population(s) into two separate groups If they come back together, any hybrids formed are less fit.
The theory of evolution is most accurately described as Group of answer choices A. Nn opinion that some scientists hold about how life originated on Earth. B. An overarching explanation, supported by much evidence, for how populations change over time and new species arise from ancestral species. C. One possible explanation, among several scientific alternatives, about how species have come into existence. D. An educated guess about how species originate. E. An idea about how acquired characteristics are passed on to subsequent generations.
DNA-sequencing studies for a gene in two closely relatedspecies produce the following numbers of sites that vary:Synonymous polymorphisms 50Nonsynonymous polymorphisms 20Synonymous species differences 18Nonsynonymous species differences 2Does this result support neutral evolution of the gene?Does it support an adaptive replacement of aminoacids? What explanation would you offer for theobservations?
the phyenotype of a population is due to mosaic of random and directed processes.some of these have to do with history some are related to adaptation,etc.as completely as posiblr,discuss the roleof chance and direction in evolution and in determing the phenotype of POPULTION
