"Evolution" is sung by Dr. Gross in the episode "Preboot." The song is about the hybrids that Dr. Gross has kept in her menagerie. It is the final song of Season 7.


Dr. Gross: Evolution's a natural process,
But it's not exactly the fastest.
You can reach your potential with just a little help.
Get some light surgery and shake off the anesthesia,
And you'll see that science has made you more special,
With just a little help.
Step into my menagerie,
One look at my lab and you'll see,
The opposite of extinction, nature leveled up.
Finn: [talking] Wow, these dudes look mad advanced.
Jake: [talking] They're mash ups, bro.
Dr. Gross: A shark that breathes air and likes to eat cheese,
Susan: [gasps]
Dr. Gross: A really fast chick with wasp wings.
Jake: [talking] Click!
Dr. Gross: An electric eel powered by wind,
When it's dark, that eel's ideal.
And one of my best hybrids, a guy that knows what time it is.


  • This song is likely an homage to Gene Wilder's "Pure Imagination" from the 1971 movie, Willy Wonka and the Chocolate Factory.
