birds are a kind, fish are a kind,....
Suggesting that hummingbirds and ostriches can interbreed? That whale sharks, hagfish, candiru, and sardines share a common, recent ancestor?
You might want to put a little more thought into that, ICANT. You are currently operating on a system like that my two-year-old grandson uses: "Fishy!" "Horsy!"
