Are humans animals?
We're in the Kingdom Animalia, but are we animals? Or does the Animalia Kingdom include humans and animals?

Scientific? Sure, see above
Everyday language? Usually not. Oh, and to avoid a common misconception: |

Are humans animals?
animals are "metazoa": muilticellular eukaryote creatures with connective tissues. Bacteria and archea are not animals as they are single-celled. Furthermore, animals must be heterotrophic, which means they don't use carbon as part of their digestion process (this excludes plants). Fungi are also heterotrophic, but there's a further distinguishing feature of metazoa: they don't have cell walls. Finally, a cherry on top, animals are mobile: they can move around. I'm not sure how sponges fit into this, so maybe they're an exception, but their look-alike ancestors are also one of the first animals.
Humans conform to all of the classifications of metazoa, so yes, they are animals. |

Dunno about you, Dremmer, but I sure am. And a mammal, and even a primate at that. Woop woop!

just look at basic characterstics common to members of kingdom Animalia. We satisfy all of them...

Humans are quite anthropocentric, they usually consider themselves as a superior being, but we're biologically animals and should be considered animals at all biological circumstances.
