Explanation / Answer
What is systematics? how is it different from taxonomy?
Systematics deal with the evolutionary relationships between organisms. Systematists try to determine which organisms share a recent ancestry with others. Systematists are concerned about the amount of evolutionary changes that may have occurred between ancestries. Taxonomy deals with classifying and naming organisms. Darwin proposed that all organisms on Earth share a common ancestor. Taxonomists make sure that organisms that do not share a common ancestor are not classified in the same group.
What is the purpose of binominal nomenclature?
There are several purposes served by binomial nomenclature.
Technically, the nomenclature includes every level of taxonomic designation, but genus and species are the only ones that really matter when you're talking to someone about something. So that's why it's binomial instead of nonnomial (for the 9 levels of classification). If you're talking about a groundhog, it can be assumed that it's an animal, a vertebrate, a mammal, etc.
The reason for not just going by species alone is that the genus kind of sets you up for what you're talking about. It's like the title page of a book or a thesis statement in a scientific paper. If you're in the field and working with groundhogs, it might not be all that important to keep saying "Marmota", but the genus does become incredibly important in other fields such as macroinvertebrate studies. When you're counting hundreds of bugs and dealing with several different genera of insects, it becomes very relevant to list both the genus and species. Saying the genus would indicate that you're dealing with mayflies instead of something like mosquitoes. Naming the species would tell you exactly which kind of mayfly it is, which can be significant in determining the health of a waterway (different bugs have different tolerances for pollution and other things affecting watershed health).
Think of it like a person's first and last name, just in different order. If someone just said "Zane", that could be any number of people. If someone said "That guy in the Magnuson family", that could also be a bunch of different people. But if someone says "Zane Magnuson", you can be pretty certain that they're talking about me. And if they are, let me know what they say.
What are the eight mandatory ranks?
Domain, kingdom, phylum, class, order, family, genus, and species.

For example, bowfin, grindle, cypress trout, and choupique are common names for the same fish, Amia calva. Cougar, mountain lion, puma catamount,
and panther describe Puma concolor formerly Felis concolor. Liriodendron tulipifera is called the tuliptree, tulip poplar, American tulip tree, tuliptree magnolia, canoe wood, and yellow poplar.
Name the six kingdoms and give example of each?
The Six Kingdoms:
What are the two major steps in buological classification?
What did linnaeus contrubute to taxonomy?
He wrote and organized descriptions of organisms in group based on their phenotype from general to specific and devise the naming system -binomial nomenclature.
How are scientific names derived?
Some organisms are named after their founder or a name sake.These names are called eponyms. As examples, the rhea Rhea darwinii is named after Charles Darwin and the southern magnolia Magnolia grandiflora is named after Pierre Magnole.
-Some scientific names relate the organism to a geographical region, such as the American alligator Alligator mississippiensis, the white-tailed deer Odocoileus virginianus, and the eastern hemlock Tsuga canadensis.
-Other scientific names are descriptive in nature, such as the mockingbird Mimus polyglottis, the flying squirrel Glaucomys volans, and the red maple Acer rubrum.
-Several scientific names are based in Greek mythology, such as the Louisiana flag iris Iris versicolor, named after Iris, the Goddess of the Rainbow.
-Some scientific names are based on word play, puns, and humor, such as a dung beetle named Ytu brutus, a rhinoceros beetle named Enema pan, a yaupon tree named Ilex vomitoria, and a spider named Darthvaderum greensladeae.
If you want to identify the various species of birds in your backyard, what sources could you use to find their scientific names?
Many useful sources: field guides, natural history book, or biological keys for organisms that are harder to identify.
How does the cladistics system of taxonomy differ from the hierarchical system of classification?
One relatively new theme that you will discover in evolutionary taxonomy is termed cladistics, or phylogenetic systematics.This basically is a system of arranging taxa by analysis of primitive and derived characteristics so their arrangement will reflect phylogenetic relationships.
