It's not necessarily evidence in favor of intelligent design, it's an illustration of an apparent anomaly in the evolutionary process.

[ConsistentLibertarian]

Unless given evolutionary theory it's more probable than not that you'd have several or many species who can show emotion, etc. this "anomaly" isn't evidence against the theory. Not, however, that you think the more complex life is the better the evidence for an intelligent designer. So on your view, the less complex life is, the worse the evidence. And it sounds like your complaining that complexity isn't broadly distributed across species.
