whether or not one is in possession of evidence adequate to justify a claim

So the definiton you refer to does NOT say 'with little or no evidence.' Thank you.

[Dante Alighieri]

That's the logical, consequence of it. A belief remains a belief *unless* it becomes justified - thereupon, it becomes knowledge. Evolution is justified by evidence. Therefore, it becomes knowledge. Your statement is fallacious.
