Not sure how but the recipe ("1 pentapod egg" > 3 "Zirconia") is unlocked at the start of the game as well as that the tech "biochamber". It's not hand craftable but is biochamber craftable. biochambers are craftable with the tech "biochamber".
While not exatly a problem its more clutter at the start of the game for no real benefit or reason.
