Absolutely the development of language, tool use, cooking are all interesting. But they're all pretty easily tied to fitness in a straight forward way. Aesthetic appreciation isn't. Sure, when I encounter a flower in the wild. I appreciate it. I grow flowers and visit gardens. But those are as much statements about me as they are about flowers. We could have had minds which are drawn to different things. You treat it as obvious and uninteresting that humans became fixated on part of another kingdom of life reproducing. I also asked a question in a public and undirected way. "IDK but it's a boring question IMO" is both not an answer, not constructive, and kinda missing the point.
