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.
It is unlikely that bees, as we know them today, were present in the Precambrian era. Bees, which are a type of insect, only evolved around 130 million years ago during the Cretaceous period. In the Precambrian era, which began around 4.6 billion years ago and ended around 541 million years ago, the Earth's early life forms were primarily simple, single-celled organisms.

What era featured the longest periods with no life forms on Earth.?
Precambrian
What era is furthest in the past?
Precambrian !!!
What is a division on the geologic time scale?
The divisions of the geologic time scale are divided into four eras. from earliest to closer to the present is the Precambrian, Paleozoic, Mesozoic, Cenozoic. During these time periods, there were several major evolutionary events. Most commonly known are the dinosaurs and humans. Hope that helped :)
Which era spans the greatest number of years in earths geological history?
The pre-Cambrian period which is a little over 630 million years ago. Before this era, there were no biota which leave a decent fossil impression - mainly soft-bodied forms. But see Ediacara in Wikipedia for more information.The earth by comparison is about 4.5 billion years since formation in roughly its present form. [So 630/4.5 000 ]
What are the four geologic time scale eras from oldest to most recent?
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
During the Precambrian era what dinosaurs were present?
a qualiopticindofsaurus
What is the era with little or no life?
The Precambrian Era. Basically, the only life present in Earth was that of single-celled bacteria.
When was the Founding Era?
the Precambrian era
Historians know least about era do?
**Precambrian**
What are two subdivisions of the Precambrian Era called?
The two subdivisions of the Precambrian Era are the Hadean and the Archean Eons.
What else besides seeweed were plants in the precambrian Era?
Seaweeds were not present in the Precambrian, The first plants were simple single celled algae or colonial varieties which formed stromatolites. There were no land plants.
What geological era do we have the least information on?
The Cenozoic, which began 65 million years ago, and includes the present times.
There was no life on land during this era?
Precambrian Era
What are some important events that happened during the Precambrian era?
It is very empty and only single-celled organisms were present in the Precambrian era. No animals were living on land because of the poisonous gas in the air.
Did the precambrian era occur first?
Yes, the Precambrian era is the earliest part of Earth's history, spanning from about 4.6 billion years ago to 541 million years ago. It is followed by the Paleozoic era.
What are the chracteristics of the geological era and the definition of precambrian Cenozoic mesozoic and paleozoic?
Precambrian
What era featured the longest periods with no life forms on Earth.?
Precambrian
