What inspired Eric Mueller to start photographing related people for his book Family Resemblance?
- The complex interplay of genes in shaping facial structures.
- The striking resemblance he saw between himself and his birth mother. (correct)
- The noticeable diversity in facial genetics among families.
- The desire to prove a strong genetic influence on facial features.
Based on the text, why do researchers like Benedikt Hallgrímsson believe gene-level explanations might not be sufficient to understand facial features?
Based on the text, why do researchers like Benedikt Hallgrímsson believe gene-level explanations might not be sufficient to understand facial features?
- Because facial genetics are too complex to rely on individual gene analysis. (correct)
- Due to the limited number of genes influencing facial shape.
- To highlight the predictability of genetic influences on faces.
- As a way to simplify the study of facial development.
What does the text suggest about predicting a person's face based on individual genes?
What does the text suggest about predicting a person's face based on individual genes?
- It is nearly impossible due to the subtle effects of each gene. (correct)
- It requires examining genes in isolation from each other.
- It is quite easy due to the significant impact of each gene.
- It involves analyzing only a few key genes.
