Let me quote some more Wikipedia at you.
Here is a discussion of feather evolution, with a phylogeny of dinosaurs that indicates the feather types known to be present in each group. You, sir, are wrong again.
Yes, they are classified as dinosaurs. They weren't in the old rank-based system, but the old system is really bad at dealing with evolution.
Therefore, by definition, we are animals.
(By the way, being an animal is not about sharing "whatever single process" with at least one animal. It's about sharing a particular
set of characteristics with most* other animals. Well, more precisely it's about descending from a particular ancestor, but I don't think "animal" has a proper phylogenetic definition yet)
*I can't say "all", because it's possible to lose some defining characteristics of a group and still remain a member of that group. I can't think of an animal example off hand, but several parasitic plants do not photosynthesise at all - nevertheless, we still call them plants, because their ancestors were plants (and they are plants in every
other respect than photosynthesis).
Nah.
Originally, it means nothing more than: find bushfire > pull out some burning stuff > take it home > feed the fire.
But come on. Why single out fire?
Probably because all sorts of other toolmaking is rampant among apes and birds? And as I said, this is backward logic. If we went hunting for unique properties as grounds for exclusion, we could probably find something in most animals. The only thing that makes fire different is that it was stumbled upon by your favourite species.
Where do you think brains capable of figuring it out come from?
