New species

Here’s the teaser from the article on newly discovered species:

“Animals found nowhere else on the planet live near deep-sea vents and get energy from breaking down chemicals such as hydrogen sulphide—not the sun.”

I have to wonder if they aren’t all congregated down there scheming for when we finally spoil our earth so badly that the human race disappears and they take over. Twenty million years from now, will these creatures be finding old MacDonald’s boxes and trying to piece together the story of those who came before them using the occasional odd find from our time?
