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.
