Vital articles in ToL
The vital articles project on English Wikipedia began in 2004 when an editor transferred a list from Meta-Wiki: List of articles every Wikipedia should have. The first incarnation of the list became what is now level 3. As of 2019, there are 5 levels of vital articles:
 * Level 1: the 10 most vital articles (2009)
 * Level 2: the 100 most vital articles (2009)
 * Level 3: the 1,000 most vital articles (2004)
 * Level 4: the 10,000 most vital articles (2006)
 * Level 5: the 50,000 most vital articles (2017)

Each level is inclusive of all previous levels, meaning that the 1,000 Level 3 articles include those listed on Levels 2 and 1.

Level 5 Animals (1,148 designated out of 2,400)

Plants, fungi, and other organisms (510 out of 1,200)
