The Kingdom of life Biologists undertake studies on living organisms in their ecosystems and classify them based on different features and the study is referred to as taxonomy. They hierarchically group the living organisms into different taxa from species, genera, families, orders, classes, phyla and kingdoms. For instance, the human taxon is classified hierarchically as follows. The species is sapiens, the genus is Homo, the family is hoinoidea, the order is primates, the class is mammalian, the sub phylum is vertebrata, the phylum is dochordata and finally the kingdom is animalia (Margulis and Chapman 8).
