User Guide

Okapiland Wildlife is an interactive evolutionary tree of mammal, reptile, dinosaur, amphibia, bird and fish. It is a javascript web application to display all the tree and navigate the species on the tree. The tree of life is displayed in two windows. The left window contains the kingdom, phylum, class, order and family. The right window contains the family, genus and species.

  1. Scroll the windows
    When one window is scrolled, another window is synchronized to show the tree structure. The followings are scrolling the windows.
    1. Scrollbar
    2. Home/PageUp/PageDn/End key
    3. Dragging the mouse (moving the mouse with left button pushed)
  2. Keyword Search
    The keyword search showes the list of classification. The classification clicked in the list is displayed, and another window is synchronized to show the tree structure.
  3. Synchronize the left and the right manually
      button to synchronize the left and the right.
  4. Command Button (left-bottom in the window)
