Animal diversity

 Biodiversity is one of the factors that affect our planet. Therefore, knowing how many species there are on Earth, is one of the simplest but most difficult questions in all of science. However, the answer to this question is not yet clear, as the biodiversity effort (cbd) is limited to date.


Moreover, precise numbers are difficult to come by, for many species have not been described, and since the earliest estimates have been based on speculative evidence. The high classification of tax types (e.g., type of grant, category, order, family and type) has a consistent and predictable approach, so that the total number of species in each tax group can be estimated.


The total number of species on earth is estimated at 3 million to 100 million. According to the most recent estimates the total number of living things on earth is 8.7 million, 6.5 million of them live on earth and 2.2 million (about 25% of the total) live deep in the oceans. About 86% of the world's species and 91% of marine species are yet to be identified, described and listed.

All 1.72 million species have been identified, about 63861 are vertebrates, 3,674,000 plants, and 1,000 000 (57.86%) are insects.

Introduction to zoology

    What is zoology ?                                  Zoology is the branch of biology  that deals with the study of animals. With the invention of microscope Darwin developed the theory of evolution which has shown the relationship between animals and human beings.  Zoology is divided into many other  branches like cell biology which deals with the structure and function of cells. Physiology deals with various reactions of the cells in the body for example respiration circulation etc. Evolution is the step by step development of a higher organisms from loyal organism. Ecology:This branch deals with habitat.In zoology we study about the animals .We study about all the processes of animals including feeding and reproduction etc.

zoology branches

  today we will see different sub branches of zoology  we   will cover the first dozen sub branches basically did you already involved the study of all the aspects of animal life from the unicellular mo beer to be change in defense and Rhino or the mighty tiger in the line and even and it even includes the study of the changes of the past ages the dinosaurs eat different tranches are as follows the first one is histology it involves the study of various tissues that form the different organs of the animals the second one is embroiled it is the study of the reproductive system animals related to the development of the Andreo that is sex organs formation of gametes that fusion and the development of families the third one cytology it deals with the study of the structure of themselves especially animal cells and they parts a fourth one cell biology it is the branch of geology that deals with all the aspects of and  cells organs cells organelles that is the study o...
