Text 1: Geneticist Park argues that humans are still evolving rapidly. Recent studies have detected selection pressure on genes related to diet, altitude, and disease resistance over the past few thousand years. Human evolution did not stop with the Pleistocene, she contends; it continues whenever environments change.
Text 2: Geneticist Hu accepts the evidence for recent selection but cautions against the implication that humans are evolving toward any new "type." Most detected signals are mild, regional, and at risk of being swamped by global migration and technology. Evolution continues in technical sense, but humans are not visibly differentiating into new forms.
Based on the texts, how would Hu (Text 2) most likely respond to Park's claim that humans are "still evolving rapidly"?
- A
He would say humans are differentiating into clearly distinct types.
- B
He would deny that any selection has occurred recently.
- Ccheck_circle
He would accept the evidence while questioning what rapidly implies in practice.
- D
He would argue that human evolution stopped with the Pleistocene.
Explanation
Hu accepts the data but qualifies the rhetorical framing. B captures this. A and C contradict him; D reverses his view.
