Forum:KB:Definition of humanoid

As some of you may have noticed, I've decided to give the Human article a major overhaul, starting with the biology section. However, I'm experiencing trouble finding a source that actually defines the term humanoid, and more specifically a source I could use as reference for the following statement: "Other sentient species with a body type roughly similar to Humans were often referred to as humanoids, since Humans were the most common example." Until now, my research hasn't been very successful. Maybe there's a related statement in The New Essential Guide to Alien Species, but I don't own that book. Could someone help me out there? Thanks in advance. --LelalMekha (talk) 12:19, September 28, 2013 (UTC)
