Animals is rather broad term. Humans are a part of the "Animal Kingdom" and both animals and humans fall under the class "mammals".
Perhaps, your youtube channel could be called:
The Mammalian Channel
It has a certain ring to it. But, this question is rather opinion-based, so whatever youtube channel name suits you is best. Perhaps try to be specific, is your youtube channel going to only look at specific animals and humans? "Humans" also has certain implications to coin videos of people, it almost sounds as if you're conducting experiments on them! Context is key.
