**Gattusa** (Rattus but with a G for germ, and with an A on the end because A) is one of the Basal Clades of Hume III, **Gattusa** is a clade that evolved from the class Grouraia, but would give rise to at least ten other classes. It started on Secundoterra, with the first species of **Gattusa** Geotoma sorgoi, which lived on Secundoterra, until it found it's way onto the other continents by rafting over to them. In the first rafting event one group of Geotoma sorgoi would raft down to Quintusterram, Ericka, and Georgia. The second rafting event another group of Geotoma sorgoi would raft East towards North Primaterra. Then a third rafting event would send another group of Geotoma sorgoi to the West toward Quartoterra. After these three events the different groups would evolved into new species, Geotoma notos on Quintusterram, and the two subcontinents, Ericka, and Georgia, Geotoma anatoli on North Primaterra, and Geotoma dytika on Quartoterra, and on Secundoterra the original species Geotoma sorgoi would evolved in the species Geotoma voreios. After all that another rafting event would send a group of Geotoma notos to South Primaterra, this group would evolve into Geotoma este. Another rafting event sended a group of Geotoma dytika more West to Terratertius, this group would evolve into Geotoma oeste. And finally one last rafting event would send a group of an unidentified species (possibly Geotoma este or Geotoma oeste) to the Cyan Islands, which at the time was the continent known as Sextusterram, this group would evolve into the species known as Geotoma sureste. These species with then go on to evolve into different tribes, Geotoma voreios would evolve into the tribe Secundoterrini, Geotoma notos would evolve into the tribe Quintusterraini, Geotoma anatoli would evolve into the tribe Voreiaprimaterrini, Geotoma dytika would evolve into the tribe Quartoterrini, Geotoma este evolved into two tribes, Notiaprimaterrini and Gattini, Geotoma oeste would evolve into the tribe Terratertini, and Geotoma sureste would evolve in the tribe Sextusterraini.

## The Extinction

After The End Of Times, Notiaprimaterrini, Terratertini, and Sextusterraini went completely extinct, Quintusterraini survived with only ten species left, and while every other tribe survived with only one species left. The Surviving Tribes would go on to evolve into more tribes, and later on would evolve into more Families, Orders, and even new Classes. The reason why so many Quintusterrainis survived is because at the time before THE END OF TIMES Quintusterram was already mostly desert, so they had a head start when it came to adapting to the new desert-like environment that the whole planet was going through.

## Evolution

On Quintusterram, the Vaktiriopodia would overthrow Skoulikigis as the dominant superclass of Quintusterram, and those surviving ten species would go on to give rise to most of the classes under Vaktiriopodia, while on the other continents the survivors wouldn't be so lucky as they couldn't overthrow the dominant superclass of each continent, so they lived in the shadow of the other superclasses. A few of the survivors from South Primaterra, and Quartoterra would end up rafting over to Terratertius, and the Cyan Islands, and after they got there they begin to evolve into new Species, Genera, Tribes, Families, Orders, and even new Classes, only one for each. South Primaterra and Secundoterra only got new classes.

Four classes of Vaktiriopodia evolved outside of Quintusterram, that's like if a group of Synapsids got cut off from the main group and survived either on an island or on another continent on the other side of the planet, and while the main group mostly died out with the few survivors becoming Mammals, the cut off group also evolved into a mammal-like form completely independently, with the only way to tell them apart being a DNA test. Or the cut off group would only look like mammals on the outside but are completely different on the inside, like msybe they don't produce milk or they are cold blooded. This is kinda what happened with Vaktiriopodia, with the Secundoterren class Anfimales (Amphimals) starting out life in the water like an Amphibian but when it is fully grown it develops a fur-like covering and doesn't need to return to the water again. The South Primaterren class Mamtiles have scaly skin like a reptiles, but produce milk like mammals do, and even has a mammalian like brain. The Terratertien class Repmals has a fur like integument but does not produce milk and has a brain similar to that of a reptile. And the Cyan Islands class Pennapiso (meaning quill back in Greek) is one of three classes on Hume III that are completely covered in quills. Anfimales has only one order alive today, Mamtiles has only one family alive today, Repmals only one genus alive today, and Pennapiso has only one species alive today.
