Recent archaeological findings suggest that the traditional view of early human migration out of Africa, often depicted as a single, rapid dispersal event, may be overly simplistic. Evidence from ancient tools and genetic markers increasingly points to multiple waves of migration over tens of thousands of years, with various groups taking different routes and interacting with local populations in complex ways. This new understanding challenges the long-held linear model, calling for a more nuanced interpretation of our ancestors' journeys. What is the author's primary purpose in the passage?

The correct answer to the question "Recent archaeological findings suggest that the traditional view of early human migration out of Africa, often depicted as a single, rapid dispersal event, may be overly simplistic. Evidence from ancient tools and genetic markers increasingly points to multiple waves of migration over tens of thousands of years, with various groups taking different routes and interacting with local populations in complex ways. This new understanding challenges the long-held linear model, calling for a more nuanced interpretation of our ancestors' journeys. What is the author's primary purpose in the passage?" is Option C: To challenge a long-standing theory about human migration with new evidence..

The other options — A) To advocate for increased funding for archaeological digs in Africa., B) To describe the various routes taken by early human migrants out of Africa., D) To compare the effectiveness of genetic markers versus ancient tools in studying migration. — are incorrect for this GMAT Exam Prep question. As explained above: The passage highlights new evidence ('Recent archaeological findings,' 'genetic markers') that 'challenges the long-held linear model' of human migration, arguing for a 'more nuanced interpretation.'
