Briefly discuss the differences in how a selectionist (one that believes that Natural Selection is a strong evolutionary force) and a neutralist (one that believes that genetic drift is a strong evolutionary force) views the following: molecular clock, evolution of coding sequences, evolution of "pseudogenes".
n your own words, explain the factors that lead to the Phenotypic variation andits importance to evolution. explain thoroughly
What is the role of variation in evolution. If heterozygosity is reduced, what happens to the potential for evolution?. The phenotype and genotype bof a population is die to a mosaic of random and directed processes, some of them have to do with history ;some are related to adaptation, etc. As completely as possible, discuss the role of chance and direction in evolution and in determining the phenotype of a population
In your own words, explain the factors that lead to the Phenotypic variation andits importance to evolution. explain clearly
Which of the following is likely to be most important in the evolution of two species from one population of another species? O some kind of barrier that physically divides the original species into two sub-populations a change in the environment such that one sub-population experiences differential natural selection O reduced performance of gametes (e.g., pollen) in crosses between sub-populations O reduced fitness of offspring resulting from crosses between sub-populations genetic divergence and cessation of gene flow between sub-populations

Recent reconstructions of evolutionary history are often dependenton assigning divergence in terms of changes in amino acid ornucleotide sequences. For example, a comparison of cytochromec shows 10 amino acid differences between humans and dogs,24 differences between humans and moths, and 38 differencesbetween humans and yeast. Such data provide no information asto the absolute times of divergence for humans, dogs, moths, andyeast. How might one calibrate the molecular clock to an absolutetime clock? What problems might one encounter in such acalibration?
Evolution in Humans 1) explain what evolutionary mechanisms are involved in creating variation in populations 2) define homology and analogy and discuss examples of each
A scientist is attempting to a cladogram that shows the evolutionary closeness of three organisms in relation to humansAfter doing DNA analysis, they that the organisms share the following percentages of DNA Organism A and humans share 85% of their DNA Organismn and humans share 80% of their DNA Organism and humans share 90% of their DNA Based on informationwhich order should they go on the cladogram ( related to most related ?
Full or partial limblessness has evolved many times invertebrates (snakes, lizards, manatees, whales). Do youexpect the mutations that occurred in the evolution oflimblessness to be in the coding or noncoding sequencesof toolkit genes? Why?
. Some scientists vigorously rejected Darwin’sideas when On the Origin of Species was published. Richard Owen (1860), perhaps the mostrespected biologist in England, wrote (amongmany other objections): “Are all the recognisedorganic forms of the present date, so differentiated, so complex, so superior to conceivableprimordial simplicity of form and structure,as to testify to the effects of Natural Selectioncontinuously operating through untold time?Unquestionably not. The most numerous livingbeings … are precisely those which offer suchsimplicity of form and structure, as best agrees…with that ideal prototype from which…vegetableand animal life might have diverged.” Howmight Darwin, or you, argue against Owen’slogic?
The ability of genomes to respond to the outside environmentby changing the developmental trajectories of organisms opens up entire worlds of research. Is evolution selecting “teams” of organisms?
