The renowned British biologist John Sulston made important advances in our knowledge of cellular biology and genetics. In scientific communities, his quote is frequently brought up when talking about specialization and expertise.

Throughout his career, Sulston studied the development of cells from embryos, with a special emphasis on the roundworm *Caenorhabditis elegans*. Because it made it possible for researchers to map out each cell division in a multicellular organism for the first time, his work was revolutionary. This accomplishment laid the groundwork for comprehending more intricate biological processes and illnesses.

Even though these topics are closely related, Sulston's quote captures the typical experience of experts being asked to comment on topics outside of their immediate area of expertise. It would be equivalent to expecting a French chef with extensive training to cook Italian food simply because they are highly skilled in the art of cooking. The particulars of every culinary tradition call for distinct abilities and in-depth knowledge, even though there may be some overlap and general knowledge that could be useful.

This quotation emphasizes how expectations that are too high for a single scientist can occasionally result from having a narrowly defined area of expertise. It also emphasizes how important it is to respect specialized knowledge while acknowledging its limitations.
