@brianjakub,
Evolution does not have to be guided by "intelligence"... and it does not have to be random either.
It can be guided by gravity and magnetism, take for instance sex. Not all sex is guided by intelligence; contrarily, it is guided by magnetism and gravity. Not all pretty people are smart.
Bio diversity implies or can be construed to mean that it somehow just popped into existence...
Evolution started with chemicals that through magnetism and gravity formed into compounds and then into structures, just like words start with syllables and then form sentences, paragraphs then entire books. Not all books require intelligence, some of them are pretty trashy and they are written completely by an animalistic urge and blind compunction.
Words are perhaps even a product of numbers.
Magnetic waves have patterns with which to "over time" organize elements into intricate forms.
And before spoken words there were mere thoughts and intentions.
Things evolve, they do not just pop into existence already fully grown and diverse. Nearly all languages evolve and take years before they are ever written.
Music is comprised of waves and vibrations at certain frequencies. Through gravity, time and tempo and ideas driven by harmonic and magnetic patterns, these waves form tones and a spectrum of instruments are devised to play them. Then composers write, and musicians practice and "over time" a performance is accomplished.
Songs just do not pop into existence all on their own without the process of music's "evolution". (if so, a lot of sound engineers would be out of a job.)
Not all music requires intelligence, sometimes it only needs a beat and an attraction to a certain melodic phrase or cadence. Time signatures are merely a form of gravity.
It is not like the body of the world's music all was "created" at the exact same moment. That is just as preposterous as believing in creationism.
Each instrument was designed at different times and each style has different eras.
Bio diversity was not created all at once but it evolved. Bio diversity is the produce of evolution and to dumb down that truth is not an act of "intelligence". No creator is needed for evolution to occur, only gravity and magnetism which the Earth has plenty of.
Bio diversity is a product of our Earth and if that is intelligent design, well then, the Earth must be pretty smart.
