Do you know what this information is based on?

Or what kind of life is being wiped out at the high-points? Plants? Animals? Insects?

It's a fairly vague graph. I clicked the link to go back to the article but the link is based on internet history... do you have the link to the article that the graph is related to?

From what i can tell, every thing. ill look for the link now

There is some bias to the data. It starts 250 million years ago, at the beginning of the Permian/Cretaceous extinction and includes several minor extinctions. It also appears to have lumped a few events.

A much better graph is given on Wikpedia:

...and there isn't a star called "Nemesis" that shows up on a regular basis. Stars (even brown dwarfs) shine rather brightly and we'd have seen the thing in our sky, even without the help of telescopes since it would be part of our solar system. It would outshine Jupiter and even outshine Sirius and the other bright stars of the sky.
