Classification of living beings- Introduction

    Look around you. What do you see? A classmate, a brother or sister? Now, look out the window, or go for a walk. You will see trees, grass, plants, dogs, cats, bugs, and many other forms of life. Now, think about this. Life extends much further than what you can see. In fact, you can find billions and billions of tiny microscopic lifeforms. And all these kinds of living things have to be identified, grouped and organized, that is, classificated in order to be identified by ourselves. The science which study the classification of living beings is the taxonomy.

    Now, discover who was the first person that thought up the taxonomy of organisms by copying this link in a new tab. Watch the video (a transcription is appeared below the video). Next, answer the questions in your notebook.

      a) Which two contributions did Linneaus to the taxonomy?

      b) Video mentions that there are two different classifications, the current one and the old one. What differences they have?

   

   As you can watch in the video, living beings are classificated by levels. Watch this video about this levels in order to understand how the classification is carried out.  

 

    Now, look the following animals up online and write their kingdom, phylum, class, order, family, genus and specie in your notebook.

lion  tiger  horse  

bear  bat  elephant

 

Do they belong to the same family? How many animals belongs to the same order? And the same class? And the same class? Why do some of them belong to the same taxon?
