Because all known living organisms share a common system for storing and utilizing genetic information, it would suggest: that all life forms on Earth share a common ancestor that the study of one organism’s genes may reveal principles that apply to other organisms thatgenesfromoneorganismcouldpossiblyfunctioninanotherorganism that all of the above ideas (1-4) are likely
Rates of evolution appear to vary in different lin-eages. For example, the rate of evolution in the rat lineageis significantly higher than in the human lineage. Theserate differences are apparent whether one looks at changesin nucleotide sequences that encode proteins and are sub-ject to selective pressure or at changes in noncoding nucle-otide sequences, which are not under obvious selectionpressure. Can you offer one or more possible explanationsfor the slower rate of evolutionary change in the humanlineage versus the rat lineage?
In a small group of people living in a remote area, there is a high incidence of "blue skin", a condition that results from a variation in the structure of hemoglobin. All of the "blue-skinned" residents can trace their ancestry to one couple, who were among the original settlers of this region. The unusually high frequency of "blue skin" in the area is an example of [ Select ] [Select] mutation natural selection sexual selection « Previous Next heterozygote advantage founder effect checkedat 9:39pm Subm

. 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?

Polar beans unike their closast relative the Black Bear, have white fur A genetic mutation has changed the gene that codes for fur color This change in fur color has allowed this species to migrate to more northern re where it was camouftaged in the snow Based on this example, which of the following most appropriately describes genetic mutations? Mutations are unnatural processes that reduce genetic diversity O Mutations are natural processes that can increase genetic diversity O Mutations are unnatural processes that are always harmful to genetic diversity O Mutations are natural processes that always affect the physical traits of organisms
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?

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?
