(I value a cat much more than a bat)

<nitpick level="extreme">Bats are no longer thought to be that closely related to us. In particular, cats and bats are both Laurasiathera, whereas we are Euarchontoglires. On the other hand, mice are Euarchontoglires too.</nitpick>

Apart from the nonexistence of humans, who are unique in their intelligence/self-consciousness/tool-use/etc., life on Earth was apparently just as diverse and grand and beautiful hundreds of millions of years ago as it is today.

<nitpick level="even more extreme">You might want to reduce that number by an order of magnitude. See http://en.wikipedia.org/wiki/Timeline_of_evolutionary_history_of_life </nitpick>

Bats are no longer thought to be that closely related to us.

Thanks! I appreciate this updating of my trivial knowledge.

Will change to: I value a cat much more than a rat.

You might want to reduce that number by an order of magnitude.

I meant times as old as, say, 200-300 Mya. The End-Permian extinction sits rather unfortunately right in the middle of that, but I think both before it and after sufficient recovery (say 200 Mya) there was plenty of diversity of beauty around.

No cats, though.

Yeah, it hadn't occurred to me to try and preserve the rhyme! :-)

Is there a blog or other net news source you'd recommend for learning about changes like "we're no longer closely related to bats, we're really something-something-glires"? They seem to be coming more and more frequently lately.

I just browse aimlessly around Wikipedia when I'm bored, and a couple months ago I ended up reading about the taxonomy of pretty much any major vertebrate group. (I've also stumbled upon http://3lbmonkeybrain.blogspot.it/, but it doesn't seem to be updated terribly often these days.)
