There was lava everywhere, and there were a lot of rain. It was very hot, with an extremely high amount of carbon dioxide in the air. In a way, it looked like the sun, but much smaller. The lava gradually started to cool down and turned into solid land as time ticked down toward the Cambrian period. At the beginning, there were near-boiling point hot spring that housed our ancestors, the archeobacteria (i think), which could survive the heat.

What were the dominant animals in the preCambrian era?
The dominant organisms during the Precambrian include the proarticulatans, such as Dickinsonia, Yorgia, and Praecambridium which were a group of "air-mattress" organisms possibly related to modern day placozoans, rangeomorphs, such as Rangea, and Charnia, which were frond-shaped organisms that had bilateral to radial symmetries, and the trilobozoans, like Tribrachidium, which were disk-like organisms with a tri-radial symmetry, possibly related to cnidarians.The ancestral mollusk, Kimberellia, is found throughout Precambrian strata of the world.There were also sponges, and what have been interpreted as the polyps and medusae of cnidarians during the Precambrian, as well. Very primitive worms and arthropods appear at the very end of the Precambrian, as it transitions into the Cambrian period.

Was a bee present in the precambrian era?
There were no bees in the Precambrian Super-Eon. In fact there were no insects of any kind in the Precambrian. It is possible that arthropods (the phylum that now includes spiders, insects, centipedes etc) evolved in the Ediacaran Period, the last geological period prior to the end of the Precambrian but these were not insects. The 1st evidence for insects comes from about 396 million years ago during the Devonian Period some 146 million years after the end Precambrian. It was not until 350 million years ago during the Carboniferous Period that there is any evidence of insect flight. The 1st evidence for bees in the fossil record come from the early Cretaceous Period about 100 million years ago. Bees, like ants are specialised wasps. Bees evolved from wasps of the family Crabrondae to specialise in eating pollen and nectar from flowers. The 1st flowers appeared in the fossil record about 140 million years ago but became widespread about 100 million years ago.
