Biologists insist that we humans share a common ancestry with all animals, and that humans are simply one very special animal which has evolved physical and cultural behavior that makes humans unique ’as the dominant animal on the Earth.
    Do you know that humans and apes have a genetic structure, in their DNA hereditary material which is more than 98% the same? This should not be misunderstood as a negative comment about humans, but as a positive comment a bout the other animals with which we share our world. Even simpler animals have many of the same genetic sequences of DNA, which permit them to carry on many of the same chemical activities in their body cells as we humans do. The process of energy production in human—technically called respiration—is nearly identical to that of tigers and birds!
    Do animals have a culture? Yes, even scholars in the social sciences now insist that animals do have cultures, each type of animal having its unique cultural characteristics.
    As part of their culture, we now recognize that some animals make and use tools, some animals can clearly share knowledge with one another, and some animals have some sort of language with which they can communicate. While these animal cultures have their limitation, it is possible to share our cultures with one another, and this has been done for many centuries. From the time that primitive man domesticated animals we have shared cultures with these animals. Sharing common resources as well as in related behavior, man is not alone in his environment.
