The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q1264048. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1910, 1927, 1956 and 1980.
