While researching a topic, a student takes the following notes:In 2014, Mikkel Schubert and Hákon Jónsson compared DNA from ancient horse bones found in Taymyr, Russia; the DNA of modern domestic horses; and the DNA of Prezwalki’s horse, which has never been domesticated. Comparative DNA analysis revealed that ancient horses and modern domestic horses shared 125 genes that Prezwalki’s horse did not. The fact that related populations of ancient and modern domestic horses share these genes, while Prezwalki’s horse does not, is evidence that those 125 genes were selected for in the process of domestication.The student wants to present Schubert and Jónsson’s study and its conclusions. Which choice most effectively uses relevant information from the notes to accomplish this goal?A 2014 study of horse domestication suggests that modern domestic horses are not descended from Prezwalki’s horses.eliminateAs part of a 2014 study of horse domestication, scientists compared the DNA of ancient horses with that of domestic and Prezwalki’s horses to find 125 genes potentially related to domestication.eliminateIn 2014, scientists studied the genetic relationship between ancient horses and domestic horses and found 125 common genes.eliminateAncient horse bones that came from Taymyr, Russia may have belonged to the ancestors of domestic horses.

Estimates of How Long Ago Dogs were DomesticatedStudy Year Subject of Analysis Approximate number of years ago dogs were domesticated Druzhkova et al. 2013 fossil remains 33,000Freeman et al. 2014 genome sequencing 11,000-16,000Perri et al. 2021 ancient/modern DNA 23,000Thalmann et al. 2014 mitochondrial DNA 18,000-32,000There is much debate in the scientific community over when exactly humans first domesticated dogs. Most researchers agree it was at least 10,000 years ago, before or coinciding with the agricultural revolution wherein ancient humans began to expend significant energy on the domestication of plants and animals. Despite this, scientists disagree about many aspects of dog domestication including when and where the first dogs were domesticated, or if they originated in one place and spread to others or were domesticated in many regions simultaneously. A student researching dog domestication hypothesizes that estimates about how long ago the first dogs were domesticated may be significantly influenced by what exactly was analyzed by the researchers in order to generate that estimate. Which choice best describes data from the table that support the student's hypothesis? The study by Thalmann et al. produced the lowest estimated minimum of how many years ago dogs were domesticated, and it was the only study which utilized whole genome sequencing to arrive at its conclusions. eliminateThe study by Druzhkova et al. analyzed fossilized remains and produced the highest estimation for how many years ago the first dogs were domesticated, while the study by Freeman et al. utilized genome sequencing and produced the lowest estimated minimum.eliminateIn their study, Perri et al. compared ancient and modern DNA from dogs, wolves, and humans, and determined that dogs were likely domesticated approximately 23,000 years ago in Siberia. eliminateThe estimated range of when dogs were domesticated suggested by Thalmann et al. contains the estimate suggested by Perri et al., while both differ significantly from the range suggested by Freeman et al.

The domestic dog (Canis lupus familiaris) originates from a wild species native to Eurasia. It also appears in the art and archaeology of ancient Egypt, where evidence verifies that Egyptians and other indigenous peoples were domesticating the creature centuries before intercontinental trade commenced over the vast land separating them from Eurasia. To decipher how the domestic dog first emerged in ancient Egypt, zoologist Sarah Petrucci and her colleagues examined the DNA of numerous ancient canine specimens, deducing that Egyptian varieties diverged from Eurasian ones over 15,000 years ago. Considering that Egypt was populated only in the last ten thousand years, the team concluded that ______13 Mark For Review13Which choice most logically completes the text?A) the domestication of dogs in ancient Egypt likely predates its domestication in Eurasia. B) Egyptian peoples likely acquired dogs from Eurasian peoples only within the last ten thousand years. C) human activity likely played no role in the introduction of dogs in ancient Egypt. D) Egyptian dog varieties likely descend from a single Eurasian variety that was domesticated, not wild.
