Dark matter is 'just right' for life

According to this article:

A new model by a scientist has determined that the amount of dark matter in our Universe is 'just right' for life to emerge.

Gee, how long did it take scientists to figure this out? Duh! If the amount of dark matter were wrong, we wouldn't be here. Might as well say "Scientists determine we do exist" or "Scientists determine we will live until we die."

But, seriously, scientists are great. In reality, last night I was up late worrying that the amount of dark matter was wrong and that life hadn't emerged. I was so confused!
