Question

Which of the following are recent observations that have challenged Tutt's hypothesis about peppered moths?

A In some areas, evidence suggests that moths rest on leaves in the treetops, not trunks.
B Light moths in some areas increased in frequency long before lichens re-appeared.
C In some areas, lichens never changed even though dark moths became predominant
D All of these

Answer 1

The correct option is D). The recent observations that have challenged Tutt's hypothesis are that moths may rest on leaves, not trunks, light moths increased before lichens reappeared, and lichens did not change in some areas even though dark moths became predominant.

Step-by-step explanation:

Recent observations have challenged J.W. Tutt's hypothesis about the peppered moths (Biston betularia). The correct answer to the question is D, all of these observations:

• (A) In some areas, evidence suggests that moths rest on leaves in the treetops, not trunks, contradicting the hypothesis that moths became more or less visible to predators depending on their coloration in relation to the color of tree trunks.
• (B) Light moths in some areas increased in frequency long before lichens reappeared, suggesting other factors may have influenced their survival rather than just the presence of lichens on trees.
• (C) In some areas, lichens never changed even though dark moths became predominant, indicating that the change in moth coloration could not be solely attributed to the presence or absence of lichens as presumed by the original hypothesis.
