The living world is very diverse. There are millions of different organisms that have been discovered, and it is estimated there are millions more yet to be found. If science did not have some kind of organized way of keeping track of all these critters, it would be very difficult to conduct any research, and information about particular creatures would never pass around the scientific community.
Just like books in the library, living things are grouped according to similar characteristics. These may be physical, behavioral, or genetic. Phylum is one of the eight major categories that can be used to organize the relationships between organisms. In order, they are: domain, kingdom, phylum, class, order, family, genus, and species.
In Ancient Greece, a man named Aristotle was one of the first to classify organisms. He put all living things within two main groups - plants and animals. He then put each of these into a smaller group depending upon where the creature lived.
It wasn't until the 18th century, when a botanist named Carl von Linné developed a system still used today. He was frustrated by the fact that some organisms had several descriptive names and others had none. He also realized that certain organisms are found all over the world, which caused them to have multiple common names. So Linné designed a system using Latin names that removed the confusion. He assigned a hierarchical classification scheme for all living things that gave each organism a two-word Latin name that was unique to it. This system of classification is called binomial nomenclature.
Taxonomy is the classification of organisms. The advent of genetic technology and DNA fingerprinting has allowed for a much more accurate and complete analysis of how organisms are related. Modern taxonomists have found that organisms that were once thought to be related are not connected at all, and others that show no external similarities are actually very similar genetically.
There are over 30 animal phyla
