TAXOCOMY

STUDY AND cataloging species

By: Valdemir Mota de Menezes, the Scribe

INTRODUCTION
Monalisa Professor in Biological Sciences course in the Department of Zoology posed the following question in the forum :
" Why is it important to study and catalog these species ? "
TAXONOMY
First we must remember that part of biology which classifies animals called TAXONOMY , word of Greek origin , moreover , the junction of two words : " Taxis" which means order, and the Greek word , " nomos " meaning law. In the eighteenth century lived Carl Von Linne , Swedish botanist and zoologist who created a classification system to group living .
In the current nomenclature of classification, we have seven categories are: kingdom, phylum, order, family , genus and species .
Living beings are considered the same species when they have similarities between themselves and are able to produce fertile children . This is the basis of the hierarchy of life .
Today there are approximately 1.7 million described species , but it is estimated that the world there are over 5 million species , therefore the majority not yet been classified .
EARTH , A WORLD UNKNOWN
Two reasons come for us to emphasize the need to continue cataloging the living beings . First , because we need to classify them in order to study them , and secondly , in possession of the classification of living things , can preserve them .
Now in July 2012 , the Official Hawaii News Now reported that millions of strange animals suddenly appeared on the island of Hawaii , several scholars have captured these animals that are being researched and cataloged , wildlife experts still argue about the origin of these animals and how they suddenly appeared on the island . Experts from the Waikiki Aquarium are eager to see these crabs grow to see how they will . Below is a picture of the animals found . The Waikiki Aquarium staff suspect they are the crab " 7-11 " , but only when these animals become adults may conclude is that if this is the same species.

CONCLUSION
End this reflection with the words of those who understand the subject:
" How can we talk about maintaining biodiversity if we do not know how many species are there? " ( scientist Edward O. Wilson )
