Index fossils :)
One Certain Protists live in colonies which can appear to be a single organism, however they show no differentiation into tissues.
they are the last organisms to appear.
One theory is that comets that struck the Earth billions of years ago contained bacteria that survived and evolved on early Earth. The evidence for this is that some microscopic images of ancient comets have what appear to be fossils of bacteria-like organisms on/in them. This is a controversial idea that is not accepted by all scientists. Some think that the fossils are actually fossils of pockets of gasses or liquid in the comet.
In the north America

That is correct. The fossil record shows that human fossils appear in Africa long before they appear anywhere else.
Fossil records are not complete. By some estimates, less than 1% of organisms that have lived appear in the fossil record.
Early humans first appeared in Africa. The oldest known fossils of early human ancestors, such as Ardipithecus and Australopithecus, have been found in East Africa, indicating that Africa is the continent where early humans originated.
545 millions years ago
That is because it is actually one continent.
reward will appear by itself once all of the skull fossils are found.
