Tree of life

Family trees are often used to depict or represent the evolutionary divergence of living creatures.  


Heritage is our legacy from the past, what we live with today, and what we pass on to future generations. It is scientifically accepted that all humankind originated in Africa.


Our tree represents the fact that, regardless of where people come from now, regardless of the language they speak, the colour of their skin, the shape of their noses, the texture of their hair, they can all trace their heritage back to the African continent.


"From the first growth of the tree, many a limb and branch has decayed and dropped off; and these fallen branches of various sizes may represent those whole orders, families, and genera which have now no living representatives, and which are known to us only in a fossil state. As we here and there see a thin, straggling branch springing from a fork low down in a tree, and which by some chance has been favoured and is still alive on its summit, so we occasionally see an animal like the Ornithorhynchus (Platypus) or Lepidosiren (South American lungfish) which in some small degree connects by its affinities two large branches of life, and which has apparently been saved from fatal competition by having inhabited a protected station. As buds give rise by growth to fresh buds, and these, if vigorous, branch out and overtop on all sides many a feebler branch, so by generation I believe it has been with the great Tree of Life, which fills with its dead and broken branches the crust of the earth, and covers the surface with its ever-branching and beautiful ramifications." 
Charles Darwin, On the Origin of Species.
