Most likely is the postulation that larger plankton developed, whose corpses and droppings were large enough to actually make it to the sea floor. This opened up the mid-ocean and ocean bottom to new life forms that could take advantage of the new nutrient sources.

What caused the end of the Archean Eon?
Nothing at all. Paeleontologists chose a time where significant numbers of hard-shelled animal fossils first appeared in rocks. It was initially believed that these were evidence of the first life on earth. As such it was decided by stratigraphers that this was a sensible point in time to create a boundary between the pre-cambrian and the newly named eon (which we are still in) - the phanerozoic, which literally means "new life".

According to the fossil record how many years ago did life first seem to appear on Earth?
The Cambrian Explosion, a period between about 540 and 530 million years ago when many major animal groups appeared in the fossil record. This is when animals first developed hard shells and skeletons, so they became much more easily fossilised. Nobody is quite sure what caused the Cambrian Explosion, but increased oxygen levels in the air after the melting of a huge ice age around 600 million years ago may have led to an increase in the size of animals in the oceans; in turn they developed skeletons and shells to support their larger bodies. The evolution of predators may have inspired prey animals to develop shells, as well. We do have fossils before the Cambrian Explosion, but these are simple, soft-bodied, small and rare, so the origins of animals are still shrouded in mystery.

When gas and fire come together what makes the explosion?
An explosion is caused by fuel burning very rapidly. The products of combustion expand rapidly and with extreme force, and the result is what we call an explosion. So...if you put gasoline on a fire and it explodes, as it will, the explosion was caused by the fire.
