Answer:
The most recent eon is subdivided into three eras and eleven periods.
Explanation:
The geological time scale has been constructed so that it can help in better research and understanding of the past, as well as making it easier to distinguish the past and its characteristics at a certain time. There are larger and smaller divisions in the geologic time scale, with the eon being the largest unit, followed by era, and then period.
The most recent eon is the Paherozoic, starting from 542 million years ago and still going on. It is subdivided into three eras and eleven periods so far. The three eras are:
- Paleozoic
- Mesozoic
- Cenozoic
The eleven periods are:
- Cambrian
- Ordovician
- Silurian
- Devonian
- Carboniferous
- Permian
- Triassic
- Jurassic
- Cretaceous
- Tertiary
- Quaternary

The tribal and national identity in Africa are a big problem. Lots of the people from certain tribes identify them selves as by the tribal identity first, and secondary by the national identity. The problem emerges when one group of people do not recognize the other group of people as part of the national identity because they differ in culture, religion, language. So this very often creates conflicts that last for years, on multiple occasions even genocides have been performed, and some tribes do not allow members of other rival tribes on the territory where they are dominant. So all in all, the national identity suffers, the people suffer, and the governments haven't been able to find a solution yet.
