My favourite subject

the subject that I like was zoology  , first because I love biology and for me is very interesting study  the anatomy of all the species (their tissues, their organs ..etc), second because through zoology you can  understand how the animals biology's sistems had been evoluted  to provide a better adaptation to their owners ( since a little worm to a big lion ) and I think that is amazing  that all the adaptations that you read in a book in 30 seconds  last more than 2000 years  to happen ,for example  the  many adaptations like changes in the muscles ,  respiratory sistem  and the skeleton     that the acquatics organism had to do  for live in earth , this fact was one of the most difficult in the evolution and one of my favourites topics too , or know that the birds had in theirs lungs gas baggs that permit their fly , and finally  because since I was in school I wanted to study this subject .
I like in specially the practises seasons because you can see in front of your eyes all the thinks that you read in books , in specially  organs that have very strange names .(Is very unhappy that some people think that this  class were against animals , because finally if one vet didn't knew well the innard anatomy of the animals ,how this vet could  do good surgeries in the future?)
