Claim CB601.1:
Peppered moths do not normally rest on tree trunks. In decades of field work, only one peppered moth was found resting on a tree trunk in the wild. Kettlewell released his moths near the ground in the morning, which would have caused the moths to land on the trunks unnaturally. Pictures showing moths on trunks were staged. This invalidates the research that was based on the assumption that they normally rested on trunks.
オオシモフリエダシャクは通常は、樹の幹の上には止まらない。数十年御フィールドワークで、自然界では、たった1回しか、オオシモフリエダシャクが幹の上にとまっているのを見たことがない。Kettlewellはオオシモフリエダシャクを朝に地上近くで放っており、それにより、オオシモフリエダシャクが不自然に樹の幹の上にとまったと考えられる。幹の上のオオシモフリエダシャクの絵は演出されたものである。樹の幹の上にオオシモフリエダシャクが止まるという仮定の上に行われた研究は無効である。
