The heirarchy consists of: domain, kingdom, phylum, class, order, family, genus, species.

There are 6 kingdoms; animals,plants,fungi, protists, archaebacteria and eubacteria.

Someone out there imagine you are a scientist trying to determin the evolutionary relationship between 2 different groups of snakes. 1st group lives in N. Ameria, the 2nd lives in Africa. The 2 groups are very stucturally similar, although the N. American ones are brown and white and the African ones are green. The 2 groups have nearly the same number of chromosome structures.
Would they share a same ancestory?
Could you classify the them as the same species?

It sounds likely that they share a quite common ancestory. If they are capable of interbreeding successfully it could be said that they are the same species. If not, one would attempt to place each in its part of the evolutionary tree through their phylogenetic characteristics.

Archeabacteria are chemosynthetic prokaryotes that live in some kind of harsh environment.
Eubacteria are groups of prokaryotes with strong cell walls and a variety of structures.
Is that right?

Yes, in the five kingdoms classification the two together are defined as monera

I tried to look up "monea" in my text book but there was nothing on it, it just listed the two seperatly.

Since wasps are multicellular consumers with complex organ systems would they belong in the "anthropod" kingdom?

Sorry im asking all these questions, im doing a test and i dont really understand alot of it, im home schooling so i dont really have a teacher to help explain things to me, so thanks for putting up with me :?

I think you mean the animal kingdom (not arthropod as that's a phylum, of which wasps also belong to)

Nathalia: I'm happy i'm helping :)

oh ok my bad.... so what kingdom do they belong to then?
So if something has a complex organ system or lacks a complex organ system how would you classify them........ would it be depending on their enviroments, or...... something else?

One must understand the properties of each kingdom. We know wasps are in the kingdom animalia (animals) for they are eukaryotic,multicellular, have nervous coordination, organ systems, are mobile etc

So then Amoebas which are unicellular consumers that lack complex orgen systems and are usually found in damp areas would belong to the Protists Kingdom, correct/
