Evolution is the framework within which these topics can be discussed. In addition, evolution applies to all life forms, not just some. It is the scientific institution's responsibility to the public not to negate pertinent information on the basis that it may not be acceptable to all. If an institution is bound by censorship of topics fundamental to its work, it is of little use in either the educational or the scientific arena. If instead, the bounds of censorship are lifted, the quality of information that can be provided to the public becomes unlimited.
Evolution is fundamental in the scientific discussion of life on earth and of the earth itself.
An institution owes its staff clear guidelines on controversial topics so that they may convey the institution's position. However, it must also respect the rights of its staff to live by whatever ideology or doctrine they choose. An institutional policy statement does not prevent controversy, but since front line staff are the ones most likely to encounter difficulties, institutional support will aid in their handling of situations that arise. Staff are not required to agree with evolution, but they are expected to be able to provide direct answers to the public as to why the institution supports evolution. Staff should not be expected to defend their personal beliefs to visitors.
