A causality paradox doesn't necessarily result in eliminating a species. By definition, 'cause and effect' initiates a paradox, which could, in a most unfortunate situation cause the elimination of a species, but could also describe altering something completely insignificant. For instance, a person named 'Adam' spelled 'Atom' takes an interest in science and later develops a means of going back in time and influencing a change in how his own name was spelled...

There are definitions on the web which I feel most appropriately describe it as an event that alters the possibility of its own occurrence, or basically, An effect that prevents the cause.

What matters here is how it was described in the resources that are acceptable here. 31dot (talk) 19:39, May 27, 2013 (UTC)
