Explanation
A. This option discusses cut marks on bones which suggests tool use for butchering but does not directly support the claim about the impact of cooking on evolution.
B. (Correct Response) This statement provides a direct comparison to the time frame required for biological adaptation to a dietary change, which is relevant to the discussion about the impact of cooking on human evolution. It supports the claim by showing that biological adaptation can occur within a time frame that is significantly shorter than the practice of cooking, suggesting that the latter could have indeed influenced evolutionary changes.
C. The adoption of fire use and climatic changes are not related to the claim about the biological impact of cooking on human evolution.
D. Strontium quantities in bones are related to diet but do not provide direct evidence of the evolutionary impact of cooking.
E. While brain volume changes are important, this option does not address the specific evolutionary impact of cooking practices which is the focus of the claim in the passage.
The evidence of biological adaptation to milk consumption within a relatively short time span supports the authors' argument that cooking, which has been practiced for a much longer time, could have significantly impacted human evolution, as indicated by the sentence preceding the parenthetical remark in the first paragraph.
