I like C.G.P. Grey's channel. Unlike cdk007's channel - which was almost exclusively about evolution - C.G.P. Grey's channel is about a whole bunch more, including points about history and some social constructions that may seem bizarre to us if we (a) happen to not be from the society that uses that particular social construction or (b) we actually stop and think about them in the first place.
Anyway, this one is about 8 misconceptions about animals. He doesn't actually go into where all of these misconceptions come from, nor does he necessarily explain them all away, but he does highlight them.
Note... if you don't agree with the "daddy long legs aren't spiders" claim, check out C.G.P. Grey's commentary about "Are Daddy Longlegs Spiders"? Short version: "daddy longlegs" is a name given to different organisms, depending on which English speaking country you call home, and only the Australian daddy longlegs is actually a spider - the US and UK ones aren't. (Ahh... language. Don't you love it?)
