This category lumps organisms of uncertain relationship. It suggests that what is categorized here somehow belongs together. This is a misconception. You can have an ape of uncertain affinity, but it needs to be categorized as an ape, or a mammal of uncertain affinity, but it needs to be categorized as a mammal, a vertebrate of uncertain affinity, and it needs to be categorized as a vertebrate, or a deuterostomate, or an animal. -Dwergenpaartje (talk) 23:03, 28 December 2013 (UTC)[reply]
