Our evo begins in the benthic landscape. The sea floor is littered with scraps of Biometal.

Here, we find our starters.

1) has a Bilaterally Symmetrical body plan and can produce vibrations that disturb the Biometal on the sea floor. They are then able to absorb this Biometal through their skin in order to power their metabolic processes. It seems that their ability to produce vibrations grants them a form of movement, though they can't control the direction. They are called Boomers due to their ability to produce vibrations and are about 1 mm in size.

2) has a Radially Symmetrical body plan, insomuch as a flat circle can have Radial Symmetry. They have a flat magnetic plate on their tops that attract metal debris disturbed by Boomers. They absorb biometal through this magnetic plate. Unlike the Boomers, they are unable to move except when acted upon by the waves. However being moved this way also risks them being turned over and becoming unable to feed. Because of their magnetic abilities, they are called Magners. They are about 1mm in diameter.
