Introduction The science and study of animal behavior involve an enormous array of complicated factors. For instance, stereotyped responses are unlearned behavioral reactions to some environmental stimulus predicated upon an organism relationship to its physical environment and anatomy. This obviously begs the question; is the observ ...

  • Biology And Human Evolution - 1,381 words
    Biology And Human Evolution Human Biology and Evolution Humans are Alive The earliest human life form can be traced back more than 3.5 billion years ago. Humans are said to be descendants of a single celled ancestor. Although they are different in size and shape all basic functions are alike. The more complex the organization of the cell became the more successful and developed it became. As these single celled organisms developed they became known as pre-humans. We share many characteristics with these pre-humans. Some of these characteristics include the masters of heredity DNA and RNA as well as proteins composed of amino acids, membranes or bound cells and lastly controlled cell division ...

That fine day was February 22, 1997. A team from the Roslin Institute which was lead by Dr. Ian Wilmut changed the face of history forever by revealing what looked like an average sheep. That sheep was what was going to be one of the most famous if not the most famous sheep in modern day. Dolly was this seven month old Trojan lambs name and Dolly was the first ever clone of a mammal.
