Feel free to substitute "scientific idea" with "idea within the scientific community". Challenges to any strictly "scientific idea" as you are thinking of them

Feel free to substitute "scientific idea" with "idea within the scientific community". Challenges to any strictly "scientific idea" as you are thinking of them are not going to come in this form of article. They will come in the form of scholarly papers and studies published in major journals. They won't be prompted by these sort of fluff questions for celebrity scientists, they will naturally arise through research. Dawkin's answer was not off; your expectations for what this question was asking and how it could be answered were off.
