Human
social cohesion is supported by subtle biological processes and feedback
mechanisms. Like trees that communicate through their root systems, human
beings have developed elaborate mechanisms to connect and share with one
another. Our nervous systems learned to treat our social connections as
existentially important — life or death.
Threats to our relationships are processed by the same part of the brain that
processes physical pain. Social losses, such as the death of a loved one, divorce,
or expulsion from a social group, are experienced as acutely as a broken leg. (Team Human By Douglas Rushkoff; pp.

SOURCE 1 The above picture was taken in 1953 when James Watson (left) and Francis Crick presented their model of a DNA molecule ( deoxyribonucleic acid model ). They had pieced together pieces of a scientific puzzle that scientists had been working on for many years. With the discovery of this model a new way of understanding life began -- humans could understand the basic building blocks of life for the first time in history. 2 Image Source 3 DNA is a double-stranded molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. 4 3,000,000 species share this genetic code. The DNA alphabet consists of four letters that represent the four chemical bases that make up the rungs of the DNA – A, T, G & C . ● A - adenine ● G - guanine ● C - cytosine ● T - thymine Be sure to note that rungs are made of combinations of “ A and T ” or “ C and G .” The h...
