Currently, scientists have defined 5 Kingdoms:
To date, our database contains information on only one these Kingdoms: Animalia
At least one and a half million species of animals have been classified and there are estimates that there may be as many as 30 million species. Of course, most of these are invertebrates - insects, mites, ticks, centipedes, crustaceans, molluscs etc. For biologists to order this mass of information, a scientific system called taxonomy was introduced.
The basic idea is to group species with similar characteristics together. Within each group, the species that share more characteristics in common are further grouped together, and so on and so on. To this end, the taxonomic categories were devised, and they create the taxonomic hierarchy. The hierarchy goes as follows: (with an example of a lizard):
Many organisms have common names, but these are often confusing as the same organism can be known in different parts of the world by many various different common names. Likewise the same common name can be applied to different species, depending on the geographical area.
There is an alternative system for categorising organisms - cladistics. This system uses the idea of ancestry as it's basis for dividing organisms into clades.
